  • The Second Unifier – Toyotomi Hideyoshi. Part Three.

    The Second Unifier – Toyotomi Hideyoshi. Part Three.

    Hideyoshi’s victory over Nobunaga’s killer, Akechi Mitsuhide, left him in a strong, but far from unchallenged position. Though Hideyoshi was arguably the strongest of Nobunaga’s remaining supporters, his power was not so great that he could overcome the others on the battlefield.

    Instead, a conference was called at Kiyosu Castle on July 16th, 1582. Historians still debate exactly what Nobunaga’s plans had been for his succession, given that his second son, and most obvious heir, Nobutada, had been amongst the dead at the Honnoji Incident. Two camps quickly emerged: Hideyoshi, supporting Nobutada’s son, Hidenobu, and Shibata Katsuie, who supported Nobunaga’s third surviving son, Nobutaka.

    The exact course of the meeting isn’t clear, but by the end of it, Hideyoshi’s faction was in the ascendancy, and Hidenobu, at just two years old, was declared Nobunaga’s heir, with Nobutaka officially acting as his guardian. There was an attempt to mollify Katsuie by having him marry Nobunaga’s sister, Oichi, a woman of impeccable rank, but the seeds of conflict had already been sown.

    In October 1582, Hideyoshi held Nobunaga’s formal funeral, and played a central, highly visible role in the ceremony, cementing his position as chief amongst Nobunaga’s retainers. Not long after this, Katsuie, supported by Nobutaka, issued letters of impeachment against Hideyoshi, who responded by demanding that Nobutaka, who had custody of the ‘heir’, Hidenobu, return him to Azuchi, as per the Kiyosu Agreement.

    Oda Nobutaka

    When Nobutaka refused, Hideyoshi used this as justification to renounce the agreement and raise an army against him. Katsuie, trapped in the north by snows and the ongoing war with the Uesugi, was unable to send help, and in a short, sharp campaign, Hideyoshi raised an army of some 50,000, forced Nobutaka to retreat, and eventually surrender, handing over Hidenobu and sending his mother and daughter as hostages to secure the peace.

    This victory did not end the war, however, and shortly after the New Year, Takigawa Kazumasu (also known as Sakon) launched successful attacks in Ise Province. Hideyoshi responded with counterattacks against Kuwana and Nagashima Castles, but the attacks failed, and he was forced to withdraw, despite an overall advantage in numbers, leaving northern Ise Province (temporarily) in the hands of his enemies.

    The situation got worse for Hideyoshi when Katsuie himself led an army of 30,000 into Omi Province, whilst Nobutaka raised another army at Gifu Castle. Katsuie also made contact with Mori Terumoto, hoping to secure his support in the battle to come. The Mori never outright refused, but instead adopted a ‘wait and see’ approach, as it was not immediately clear which side would win.

    Throughout spring and early summer, the two sides clashed in skirmishes in Ise, Mino, and Omi Provinces, and the momentum would swing back and forth for some time until a decisive engagement near the fortress at Shizugatake. Hideyoshi’s forces were aided by the timely arrival of reinforcements from across Lake Biwa, and the betrayal of Maeda Toshiie, one of Katsuie’s most important generals, who switched to Hideyoshi’s side, for reasons that are still debated.

    By all accounts, Katsuie and his army forced tenaciously, but with Toshiie’s betrayal, they were outflanked and outnumbered, and Katsuie was forced to retreat. He got as far as Kitanosho Castle, in modern Fukui, where Hideyoshi’s forces laid siege.

    The night before the final assault, Katsuie held a final banquet with his close family and retainers, whilst his wife, Oichi, made arrangements for her three daughters to be protected by Hideyoshi and avoid what was to come. Despite pleas to save herself, Oichi refused to leave her husband’s side.

    A later depiction of Shibata Katsuie preparing for battle, with Oichi beside him.

    The attack started at dawn, and despite stiff resistance, by midday, the battle was clearly lost, and Katsuie retreated to the main castle, where he and 80 members of his family, including Oichi, killed themselves. Calling it ‘suicide’ is perhaps a bit generous, as the records suggest that a large number of the dead were children. When it was over, Katsuie’s forces ignited a store of gunpowder, blowing the tower apart and bringing a spectacular end to the Shibata Line.

    “Katsuie, a martial artist, fought seven times but was unable to defend himself. He climbed to the ninth floor, the highest level of the main tower, and addressed the entire group, loudly proclaiming, “Watch Shuri’s hara-kiri and learn from it.” The samurai, with their hearts in tears, wet their armor sleeves. As everyone fell silent, Katsuie stabbed his wife, children, and others to death, then committed seppuku with 80 others. It was the hour of the tiger (5:00 PM).”

    Hideyoshi’s letter to Kobayakawa Takakage dated May 15, 1583,

    Just a side note, the actual record of Katsuie’s suicide is pretty harrowing stuff, and it’s always difficult to read about the death of women and children who weren’t guilty of anything other than being related to the losers. This kind of thing was expected, though; even children weren’t generally shown mercy, and though there are notable examples (Oichi’s daughters, for instance), if a child was caught in a siege, they generally died in the same manner as their parents.

    With Katsuie crushed, Hideyoshi was able to extend his direct control over the northern provinces of Koto, Noto, and Echizen, and when Nobutaka committed seppuku, and Kazumasu surrendered, Hideyoshi had established himself as the most powerful man in the realm and while Hidenobu (still just an infant) remained as the nominal ‘heir’ there was no no doubt that Hideyoshi was in charge.

    In 1583, construction began on Osaka Castle, built on the former site of the Ishiyama Hongan-ji Temple complex. It would eventually become Hideyoshi’s base and was widely considered one of Japan’s finest castles. Meanwhile, in the Kanto, a marriage alliance between the Tokugawa and Hojo presented a clear threat to Hideyoshi’s power.

    In early 1584, Oda Nobukatsu, another son of Nobunaga, rebelled against Hideyoshi, quickly gaining the support of Tokugawa Ieyasu and Chosokabe Motochika, who raised armies of their own in opposition to Hideyoshi. Despite a huge advantage in manpower (some sources say 3-to-1), Hideyoshi struggled to achieve a decisive victory.

    Tokugawa Ieyasu

    Some initial success in Ise Province was followed by a defeat at the Battle of Haguro Castle, after which Hideyoshi, who had been waiting at Osaka Castle, took the field himself, meeting Ieyasu near Komaki (near the modern city of the same name). Again, despite a significant manpower imbalance, Ieyasu’s strong position meant that Hideyoshi was unable to force a decisive engagement, and both sides focused on reinforcing castles and constructing new earthworks in anticipation of the fight to come.

    The campaign that followed is often called the Battle of Komaki and Nagakute, after its two most decisive engagements, but there were actually a series of sieges, counterattacks, and skirmishes over the summer and early autumn of 1584. The fighting would result in a tactical victory for the Tokugawa, as they would arguably have the best of the fighting. On the other hand, the strategic situation favoured Hideyoshi, and he would ultimately be able to secure control over his new territory and the power that went along with it.

    In the end, both sides had bigger problems. Ieyasu’s domains were under severe economic strain from the war, and a series of floods, combined with the burden of having a large number of peasants away at war, drained his treasury and threatened famine (this was before a serious earthquake in 1586 compounded his problems).

    For his part, Hideyoshi’s position was not as strong as it appeared. Though he had the advantage in men, he also had powerful enemies elsewhere, enemies that were arguably more pressing problems than Ieyasu, who had proven he could hold Hideyoshi off, but not that he could mount a serious attack of his own.

    Despite his inability to defeat Ieyasu, by the dawn of 1585, Hideyoshi was effectively the ruler of Japan, already on the verge of surpassing his nominal masters (the Oda), and about to launch the campaigns that would finally bring an end to the centuries of bloodshed.

  • The Second Unifier – Toyotomi Hideyoshi. Part Two.

    The Second Unifier – Toyotomi Hideyoshi. Part Two.

    In 1577, a dispute between Toyotomi Hideyoshi and Shibata Katsuie led to Hideyoshi taking his army home, and leaving Katsuie to battle the mighty Uesugi Kenshin alone, a battle he lost. In the aftermath, Hideyoshi had every reason to fear the wrath of his master, Oda Nobunaga, and he was arguably lucky to keep his head, let alone his position.

    A 19th-century depiction of Hideyoshi in Nobunaga’s service.

    Nobunaga was well known for his ferocity, but he recognised capable subordinates. Hideyoshi had been reckless, but he had also earned a reputation as a good administrator and leader of men, and it wasn’t long before he was back in the Great Lord’s good books. In late 1577, he was dispatched west to contend with the powerful Mori Clan and by the end of the year, he was in control of Harima Province and advancing into neighbouring Tajima.

    During this period, Hideyoshi made the famous Himeji Castle his base and used it as a springboard for a series of successful campaigns against the Mori over the next few years. By late 1578, he had subjugated (either through conquest or submission) Bizen and Mimasaka Provinces, in addition to his earlier conquests, and he was poised to advance further when the Araki Clan, based at Arioka Castle, rebelled, obliging him to redeploy his forces to put them down.

    Able to resume his advance in 1580, Hideyoshi secured Tajima Province, bringing the once-mighty Yamana Clan under his control and incorporating many of their former vassals and members of the clan itself into the new administration, a policy widely praised as the reason that Tajima was swiftly pacified.

    By 1581, he had advanced into Bitchu Province and secured Awaji Island for his master, utilising slow but effective siege tactics, starving his enemies into submission, a time-consuming but strength-preserving strategy. One disadvantage, though, was that it meant you were easy to find should your enemy have sufficient strength elsewhere.

    The area that Hideyoshi either conquered or was fighting in during this period.

    In Spring 1582, Hideyoshi led an army of some 30,000 to besiege the mighty fortress at Takamatsu. Strategically vital for control of Bitchu Province, the castle was defended by 3,000 Mori warriors, who quickly called for aid. Mori Terumoto responded and began mustering an army that would eventually number over 50,000. Hideyoshi now faced a problem: already outnumbered, if he tried to take the formidable fortress by storm, he’d deplete his forces further. On the other hand, trying to starve the garrison, who knew help was on the way, would take too long and risk trapping his army between the walls of the fortress and the vengeful spears of the Mori.

    Hideyoshi responded in a typically inventive fashion. Unable to take the castle by storm, he ordered a levee built and the nearby river dammed, diverting water into Takamatsu itself, flooding the castle to such an extent that the garrison’s food supplies were almost completely ruined and they were reduced to communicating by boat.

    A later depiction of the Siege of Takamatsu Castle. The tower to the left is Hideyoshi’s observation post, and you can see the castle itself flooded in the background.

    Despite this, the castle still held out, and when news arrived that Terumoto was on the march, Hideyoshi sent a message to Azuchi, requesting immediate reinforcement from Nobunaga. Sensing an opportunity to catch the powerful Mori clan in open battle, where they could be destroyed, Nobunaga quickly dispatched Akechi Mitsuhide to reinforce Hideyoshi, while he went to Kyoto to make arrangements for a larger force that would be sent to finish the job.

    As we already know, Mitsuhide never arrived; instead, he turned his forces around and attacked Nobunaga at his base at Honnoji, killing him and his heir. Hideyoshi was well placed to respond to this betrayal, and he swiftly concluded a peace treaty with the Mori (who were apparently initially unaware of Nobunaga’s death). Some have speculated that his rapid reaction is evidence of his involvement, or at least foreknowledge of the plot, though there’s nothing concrete to suggest that he was anything other than in the right place at the right time.

    More to the point, Hideyoshi was far from the only player on the board. Hideyoshi’s former rival, Shibata Katsuie, was to the north, with an army facing the Uesugi, while in the Kanto, Takigawa Kazumasu (sometimes called Sakon) had a large army intended to monitor the Hojo. Nobunaga’s son and heir had been killed during the Honno-ji Incident, but his third son, Nobukatsu, had gathered a force at Sakai (modern Osaka) to conquer Shikoku.

    Any one of these forces could have been the one to avenge Nobunaga’s death and put an abrupt end to Akechi Mitsuhide’s ambitions. Even Tokugawa Ieyasu was a potential avenger, making his famed escape from mortal danger with the (supposed) help of the famous Ninja of Iga. Ieyasu would return to his home in Mikawa and gather his forces, but events would move quickly, and though all parties moved against Mitsuhide, it was Hideyoshi who struck first.

    Tokugawa Ieyasu as he appeared in later life. He was close to Kyoto during the Honnoji Incident and was forced to make a dramatic escape back to Mikawa. Hideyoshi would prove to be faster, but Ieyasu’s time would come.

    In the days following the Honnoji Incident, Mitsuhide moved to consolidate his position. Unfortunately for him, he faced harsh military and political opposition. On the one hand, Nobunaga’s body had not been recovered from the flames, and rumours abounded that he was still alive. Even among those who may have believed Nobunaga was dead, Mitsuhide commanded little respect. He was a traitor, after all, and surrounded by enemies who wished to avenge Nobunaga and take power for themselves.

    Militarily, Mitsuhide was too weak to assert effective control over much territory. He had between 13,000 and 15,000 men, but was obliged to capture and garrison several important castles, whittling his already limited forces down still further. Then there was the speed at which Hideyoshi moved. Mitushide arguably did what he could, and with the limited communications and transportation available at the time, it’s hard to see how he could have moved faster, but Hideyoshi was faster still, and on July 2nd, 1582, just 12 days after Honnoji, the two sides clashed at the Battle of Yamazaki, to the south-east of Kyoto.

    Akechi Mitsuhide. Historians debate why he decided to betray Nobunaga, but within two weeks of the incident, he’d be dead.

    The numbers vary by source, but Hideyoshi is said to have had between 20 and 40,000 men, while Mitsuihides had 10 to 16,000. Despite the long odds, Mitsuhide’s army was well-positioned, and the ground around Yamazaki was boggy, limiting movement and reducing Hideyoshi’s advantage in numbers.

    Mitsuhide probably understood that a defensive victory against difficult odds would have greatly enhanced his prestige, and for most of the day, Hideyoshi’s army took heavy losses in vicious frontal assaults. Around 4pm, however, reinforcements arrived for Hideyoshi, outflanking Mitsuhide’s position, and causing his army to fall back. As the battle moved to higher and drier ground, Mitsuhide’s force was gradually surrounded and forced back.

    The battlefield of Yamazaki as it appears today. Historians believe the heaviest fighting took place around the bypass that can be seen in the centre.

    Later sources suggest that the casualties were about the same (around 3,000 each), but under attack from three sides, the morale of Mitushide’s army broke first, and by sunset, their retreat became a rout. When the battle was over, it is said that Mitsuhide had just 700 men remaining. His exact fate isn’t clear; some say he was wounded and committed seppuku, while others suggest he was killed by vengeful peasants or bandits. Either way, his head was brought to Hideyoshi the day after the battle, and then displayed at Honnoji, a powerful statement confirming Hideyoshi as Nobunaga’s ‘avenger’ and giving an enormous boost to his credibility.

    Hideyoshi would spend a few weeks stamping out the last embers of Mitushide’s rebellion, but despite his military successes, he was not unchallenged as Nobunaga’s successor. The other players, who had all been poised to strike, still remained in the field, and each had their own ambition to rule, either directly or through one of Nobunaga’s other sons.

    This would result in the Kiyosu Conference, but we’ll cover that and its consequences next time.

  • The Second Unifier – Toyotomi Hideyoshi. Part One.

    The Second Unifier – Toyotomi Hideyoshi. Part One.

    If the bird will not sing, make it sing.

    Oda Nobunaga’s death in June 1582 left a power vacuum that was ultimately filled by Toyotomi Hideyoshi (then using the family name Hashiba). Hideyoshi’s tale is remarkable even by the standards of the time: from peasant footsoldier to master of the realm, he epitomised the danger and opportunity of the Sengoku Jidai and would be the man most responsible for bringing it to an end.

    Hideyoshi’s origins are suitably mysterious and have been subject to a fair bit of speculation and mythologising, mostly by the man himself. After his rise to power, he is supposed to have spread the rumour that he was a secret bastard of the Emperor, stating that his mother had been a maid in the Imperial Palace and had “grown close to the Emperor’s Body”, which is quite the thing to say about your own mother.

    Hideyoshi’s mother. She is often called Omandokoro, though this is the name she took after becoming a nun, and most sources think her birth name was Naka.

    Less mum-shaming sources suggest that Hideyoshi was born in 1536 or 37 in Owari Province, now part of the modern city of Nagoya. His father, usually recorded as Kinoshita Yaemon, is a similarly mysterious figure, but historians generally agree he was probably of the lower classes, most likely a peasant soldier (Ashigaru). Hideyoshi’s childhood is also poorly recorded, with some sources suggesting his father died when he was 7, after which Hideyoshi entered a monastery, though he left shortly afterwards.

    At the age of 15, he received part of his inheritance and left home to become a wanderer. Sometime later (the dates are unclear), he is recorded as Kinoshita Hideyoshi in the service of the Iio Clan, which, in turn, was a vassal of the Imagawa Clan. It’s not certain exactly when he came into the service of the Oda Clan, but it appears to have been before 1554, when he was serving at Kiyosu Castle (under Oda control) in charge of the kitchens, and in some kind of role in construction or maintenance.

    Kiyosu Castle as it appears today.

    Even this is a matter of some debate, though, as other sources state he didn’t join the Oda until 1558 (though they agree he served at Kiyosu Castle), and a common origin story in English language sources is that he was Nobunaga’s sandal bearer, a story which possibly reflects his role as a kind of ‘military servant’ which might explain how he was able to gain recognition from Nobunaga.

    Even the matter of Hideyoshi’s marriage is subject to debate; it is certain that he married Nene, but her origins and even the year of the marriage aren’t totally clear. Some sources say the marriage took place in 1561, when Nene was 12 or 13, and Hideyoshi was in his 20s. This earlier date is controversial because even though 13 was the age at which girls became adults (legally speaking), it was still considered unusual for a girl to marry as soon as she came of age.

    Hideyoshi’s wife, Nene, who also became a Nun, is often recorded as Kodai-in as a result.

    Another theory is that the marriage took place in 1565, when Nene was 16 or 17, still young by modern standards, but a far more acceptable age at the time. Nene’s adoptive father was Asano Nagakatsu, who would later receive a stipend of 300 Koku from Nobunaga and served as one of his bodyguards. This status suggests that Nagakatsu was of sufficient rank, and the marriage to Nene is often cited as evidence that Hideyoshi was already moving up in the world by the mid-1560s.

    As well as his marriage, further evidence of his rise in Nobunaga’s service appears in 1565 when his name appears as the co-signer on documents assigning fiefs, suggesting he was already one of Nobunaga’s most important vassals. Throughout the back half of the decade, he is recorded as having taken part in several of Nobunaga’s campaigns, notably taking Mitsukuri Castle during the Omi Campaign in 1568.

    In 1569, in support of the Mori Clan (who were his temporary allies), Nobunaga dispatched a force of some 20,000 to support them against a rebellion, whilst the bulk of the Mori forces were in Kyushu fighting the Otomo clan. This army, led by Hideyoshi, was, by all accounts, a phenomenal success, capturing no fewer than 18 castles in just 12 days and ending the rebellion swiftly.

    A year later, he was part of Nobunaga’s campaign against the Asakura Clan of Echizen Province, which ended when Nobunaga’s brother-in-law, Azai Nagamasa, switched sides, threatening to cut off Nobunaga’s retreat. Though the exact scale of the threat is debated (as I mentioned in my posts on Nobunaga himself), what is certain is that Hideyoshi led the rearguard and was instrumental in ensuring that his master was able to escape.

    Azai Nagamasa, Nobunaga’s brother-in-law, whose betrayal nearly spelt disaster for his campaign.

    After the Battle of Anegawa, in which Nobunaga avenged himself on the Azai-Asakura forces, Hideyoshi was appointed castellan of the strategically important Yokoyama Fortress, from which he would be tasked with keeping up the pressure on the remnants of the Azai-Asakura until their final destruction in 1573.

    I’ve previously mentioned the tradition of changing names among Samurai and how it often leads to confusion when you’re trying to source information about specific figures who may have had several names. While Hideyoshi is generally remembered as “Toyotomi Hideyoshi” in English-language sources, this wasn’t his name until much later. His peasant origins mean that he likely didn’t have a surname at all, and the names he was known by later were either taken from places or bestowed by others.

    Shibata Katsuie
    Niwa Nagahide

    In 1573, Hideyoshi adopted the name Hashiba. The origins of this name are somewhat unclear; a common theory is that he took one character each from Shibata Katsuie and Niwa Nagahide (the Japanese character ‘wa’ can also be pronounced ‘ha’), though this is disputed.

    Along with a name change, the fall of the Azai Clan in 1573 resulted in Hideyoshi receiving their former lands around the shores of Lake Biwa. He based himself at Imahama, which is promptly renamed Nagahama, after Nobunaga. This was not some unique quirk of his, by the way, the ‘giving’ of character from prestigious names was a common occurrence, and was generally treated as a respectful and honoured thing to do.

    He continued to play a significant role in Nobunaga’s military expansion, serving at the decisive Battle of Nagashino in 1575, and capturing Kiriyama Castle from the powerful Kitabatake Clan of Ise Province the next year. In 1577, Hideyoshi’s star seemed to be on an inexorable rise, but personal rivalries would get in the way.

    Nobunaga dispatched an army under Shibata Katsuie to face Uesugi Kenshin in the north. Now, you may remember from my post about him, but Kenshin was a formidable opponent, a rival to both Hojo Ujiyasu and Takeda Shingen; he was certainly not a man to take lightly. Nobunaga obviously understood this and dispatched reinforcements commanded by Hideyoshi.

    Uesugi Kenshin

    At this point, a simmering feud between Hideyoshi and Katsuie exploded. The exact nature of the argument isn’t recorded in contemporary sources, and later writers could only speculate; however, it is known that Hideyoshi literally took his army and went home. This open defiance of Nobunaga’s orders would have been bad enough, but when Katsuie was defeated shortly afterwards at the Battle of Tedorigawa, Nobunaga was furious.

    Hideyoshi was arguably lucky to keep his head after that, and he would spend some time in the political wilderness. His time would come again, however, and we’ll talk about that next week.

  • The Honnoji Incident – Oda Nobunaga. Part Four.

    The Honnoji Incident – Oda Nobunaga. Part Four.

    “The enemy is at Honnoji” – Akechi Mitsuhide

    By 1582, Oda Nobunaga was the most powerful man in the realm; in fact, it could be argued that he was the most powerful man Japan had seen in centuries. A combination of ruthless political manoeuvring and brutal military campaigns had left him on the verge of finally reuniting the nation and ending the Sengoku Jidai.

    Only the Mori Clan still had the strength to stifle Nobunaga’s ambitions, and in May 1582, he announced his intention to march against them with all his might. The catalyst for this next campaign was a message from Hashiba Hideyoshi, who was besieging Takamatsu Castle (in modern-day Okayama). The message read that Mori Terumoto was marching to relieve the siege, presenting Nobunaga with an opportunity to meet the Mori in open battle and crush them.

    A scene from the Battle of Takamatsu Castle. Hideyoshi attempted to end the siege by flooding the castle, a tactic that was ultimately unsuccessful.

    It is generally accepted by historians that Nobunaga intended not only to defeat the Mori but also subjugate Shikoku and, eventually, Kyushu as well, viewing the campaign against the Mori as part of a wider strategy to bring the entire nation under his command. In preparation for this, he dispatched several generals to support Hideyoshi, most notably Akechi Mitsuhide.

    In the days that followed, Nobunaga was seen to be in good spirits and laid on lavish entertainment for those who came to visit him, including Tokugawa Ieyasu, who departed Azuchi on June 21st, embarking on a tour of Kyoto, Osaka, and the surrounding region. On the same day, Nobunaga’s son and heir, Nobutada, arrived in Kyoto for reasons that aren’t entirely clear (some speculate he meant to accompany Ieyasu). Whatever his purpose, his arrival in the capital meant that when Nobunaga himself departed Azuchi for Kyoto on June 29th, father and son would be in the same place, at the same time.

    Azuchi Castle, Nobunaga’s base, as it appeared around 1582.

    Exactly why Nobunaga went to Kyoto first is debated, with some suggesting he planned to attack Shikoku first, going via Kyoto and the port at Sakai (modern Osaka). Other sources say he went to deal with negotiations at the Imperial Court, and others still suggest he wanted to show off a new tea set he had recently acquired. (This may sound a touch comical to a modern audience, but the tea ceremony was a serious matter in Japan at the time.)

    On June 30th, Nobunaga held said tea ceremony, which was followed by a drinking party, during which Nobunaga’s son, Nobutada, arrived, and father and son drank and talked together, little knowing that it would be their last meeting. Sources tell us that the party ended late, and Nobutada returned to his accommodation at nearby Myokakuji Temple, and Nobunaga retired for the night shortly afterwards.

    Oda Nobutada, Nobunaga’s son and heir.

    Though Honnoji was a temple, as the primary residence of Nobunaga in Kyoto, it wasn’t undefended. Excavations in 2007 found evidence of a moat and some earthworks, suggesting that the site had been partially fortified, though it was far from a fortress, and Nobunaga was protected by only a few dozen servants and his personal entourage.

    Nobunaga clearly didn’t expect to be attacked, and why should he have? He was the most powerful man in the realm, in the heart of the capital city, with hundreds of thousands of warriors at his command. His enemies were far away, and even in the unlikely event that the army under Hideyoshi was defeated, he could call on other, just as formidable forces.

    Honnoji as it appears today. The current temple is located at a different site from that in 1582; after being rebuilt by Hideyoshi in 1592, it was destroyed by fire in 1788 and 1864, and then underwent further renovation in 1928.

    One of these was a force of around 13,000 men under Akechi Mitsuhide. In the afternoon of June 30th, Mitsuhide claimed to have received a message from Nobunaga, instructing him to bring his force to Kyoto for review. The letter, if it existed at all, was certainly a forgery, but by that evening, Mitsuhide had arrived at Kameyama (modern Kameoka), north of Kyoto. By the next morning, they had reached the Katsura River, and at this point, it is unclear if Mitsuhide’s army understood their objective.

    Sources from men serving in this force suggest they believed that they were going to attack Tokugawa Ieyasu, nominally on the orders of Nobunaga himself. This is supported by the semi-contemporary “History of Japan”, written by the Jesuit, Luis Frois, which suggests that Mitsuhide’s army believed they were acting under Nobunaga’s secret order, at least initially.

    Akechi Mitsuhide, the man behind the Honnoji Incident.

    At this point, Mitsuhide is supposed to have uttered the famous phrase “The Enemy is a Honnoji” announcing his rebellious intention (as everyone knew that was Nobunaga’s base.) Unfortunately, as dramatic as that scene might have been, the first source for it doesn’t appear until 1641, nearly 60 years after the event, and there are no contemporary sources that tell us what Mitsuhide might or might not have said.

    What we know is that by dawn, Mitsuhides forces had surrounded Honnoji. What followed was a bloody, but ultimately one-sided fight. All sides agree that Nobunaga and his pages fought bravely, but they were hopelessly outnumbered, and the fighting was over by around 8am. We don’t know exactly how Nobunaga died, but the sources agree that he fought with a bow, and then a spear, before suffering some kind of injury (the sources differ) and retreating into the already burning Honnoji, where he presumably committed seppuku.

    A 19th-century depiction of Nobunaga’s last stand. Though we don’t know exactly how he died, sources agree he fought bravely until an injury forced him to retreat.

    Nobunaga’s son, Nobutada, had, upon hearing that Honnoji was under attack, rushed to help, only to be overwhelmed and forced back to his own accommodations at Myokakuji Temple, where he too was forced to commit seppuku as the temple burned around him, his body consumed by the flames.

    Rumours of their survival sprang up almost immediately. Since neither body was ever identified (this being before DNA or dental records), Mitsuhide could not prove the deed was done, and any hope he had of securing support went up in the same smoke that Nobunaga and his son had.

    Another 19th-century depiction of Nobunaga’s end. Though heavily stylised, it displays the flames that would ultimately consume Nobunaga’s body.

    Whatever his actual motivation (which we’ll look at in a moment), Mitsuhide’s triumph would be short-lived. Though his forces had successfully killed Nobunaga, his son, Nobutada, and most of his inner circle, and secured Kyoto, the same forces that Nobunaga might have called on to defend him were now focused on avenging him.

    Mitsuhide swiftly withdrew to Azuchi Castle, from where he tried to rally support, and wrote to the Imperial Court, seeking to legitimise his position. There are no records of any response, and he soon ran out of time. Hashiba Hideyoshi had made peace with the Mori (who were apparently initially unaware of Nobunaga’s death) and was now marching against him.

    The site of the Battle of Yamazaki as it appears today, seen from Mt Tenno, from which the battle is sometimes called The Battle of Tennozan.

    Mitsuhide was outnumbered two or three to one, and at the Battle of Yamazaki on July 12th, he was decisively defeated. Although losses were similar on both sides (about 3000), Mitsuhide’s army suffered from serious morale problems and disintegrated as the battle went against them, leaving Mitsuhide with just 700 warriors at day’s end.

    Mitsuhide himself survived the battle, but he was either killed in the aftermath (possibly by bandits or opportunistic peasants) or else committed suicide due to injuries sustained on the battlefield. Whatever his end, he was definitely dead by the time his head was displayed outside the burned remains of Honnoji Temple, on or around July 17th.

    Akechi Mitsuhide’s grave at Saikyoji Temple in Kyoto.

    No sooner was Mitsuhide dead than questions were raised about why he had betrayed his lord. Though Samurai overthrowing their overlords was nothing new, Nobunaga was uncommonly powerful, and his death threatened to unravel the fragile peace he had secured, especially in light of Mitushide’s failure to secure support or legitimacy in its aftermath.

    Contemporary scholars and modern historians continue to debate exactly why Mitsuhide betrayed Nobunaga. He was certainly mistreated and often humiliated, sometimes even being publicly beaten by Nobunaga himself, so simple revenge is a possible motive. Other sources suggest it was to avenge his mother, who had served as a hostage to secure a truce years earlier, only for Nobunaga to break it, resulting in the poor woman being executed.

    Mitsuhide’s mother hangs from a tree in consequence of Nobunaga breaking the truce that her life was the guarantee of.

    If public humiliation and the death of his mother weren’t reason enough, some suggest it was pure ambition; Mitsuhide may simply have wanted the power for himself, and he certainly wouldn’t have been the first to try it. Indeed, some historians speculate that if he had been able to prove that Nobunaga was actually dead, he might have gained some support, and the outcome could have been different.

    Others suggest that Mitsuhide was a partisan of the Shogun, or possibly the Imperial Court, and overthrew Nobunaga in order to restore one or the other to power, though these ideas only emerged in the 20th century, and there’s little contemporary information to go on.

    Nobunaga publicly beats Mitsuhide. Quite why Nobunaga treated him so poorly isn’t clear, but the humiliation almost certainly contributed to his decision to rebel.

    There’s also the speculation that Mitsuhide was working with one of Nobunaga’s other vassals. Some historians argue that Hashiba Hideyoshi was able to turn his army against Mitsuhide very quickly, leading to speculation that he knew the attack was coming. Historians have never conclusively dismissed this, though it has been pointed out that only the fastest of Hideyoshi’s troops actually made it to the Battle of Yamazaki, meaning that the quick turnaround might not have been that quick after all.

    Other theories blame the Imperial Court, or the Mori Clan, for conspiring against a man who had proven to be an existential threat, as well as the Buddhist Clergy, who had plenty of reason to want vengeance on Nobunaga.

    A contemporary depiction of Mass. Though largely dismissed by historians, the possibility that the Jesuits feared Nobunaga would turn on them contributed to the theory that they were involved in his death.

    Another possibility is the Jesuits, who are suggested to have feared that Nobunaga might move against them, though there’s little evidence that he intended to (as he valued foreign trade), and Hideyoshi, his ultimate successor, would prove to be a far greater threat to Christianity in Japan.

    Ultimately, most of this speculation comes from later sources, and there’s no way to know what Mitsuhide intended, only that his plans fell apart before being decisively ended on the battlefield at Yamazaki.

    Hashiba (later Toyotomi) Hideyoshi. His victory at Yamazaki did not make him Nobunaga’s successor, but it did wonders for his prestige.

    Hashiba Hideyoshi’s victory did not mean he inherited Nobunaga’s power, however, and the power struggle that followed threatened to undo the Great Lord’s work, but that’s a story for another time.

  • The First Unifier – Oda Nobunaga. Part Three.

    The First Unifier – Oda Nobunaga. Part Three.

    By 1573, Oda Nobunaga was arguably the strongest warlord of his day, controlling a large territory that dominated central Japan. He had taken control of Kyoto and brought about the end of the Ashikaga Shogunate (though he would never take the title for himself), and with the death of Takeda Shingen, his most dangerous rival had been removed.

    You probably know by now that even a strong position was never completely unchallenged during the Sengoku Jidai, and Nobunaga still had enemies to deal with. In the summer of 1573, he launched a campaign against the Azai-Asakura alliance, whom he had defeated at the Battle of Anegawa in 1570 and now meant to finish off.

    Nobunaga’s forces laid siege to the formidable Odani Castle. When Azai-Asakura forces marched to relieve it, they were ambushed and forced to retreat to Ichijodani Castle with Nobunaga in hot pursuit. The Azai-Asakura were then decisively defeated at the Battle of Tonezaka and tried to retreat again; however, a series of defeats, betrayals, and suicides put an end to the alliance and then to the clans themselves.

    A side note to these events is the end of the marriage between Nobunaga’s sister, Oichi, and Azai Nagamasa, lord of the Azai Clan. When Nagamasa betrayed Nobunaga, Oichi remained faithful and was by his side as Odani Castle came under siege. Some sources say that Oichi gave birth to her third daughter during the siege (though others disagree). There is also debate over how she escaped, with some saying she was aided by a loyal retainer, and others stating that Nobunaga and Nagamasa agreed to let Oichi and her daughters go, a tale often romanticised as demonstrating the love both men had for her.

    Romantic stories aside, with the end of the Azai-Asakura threat, Nobunaga turned his attention to the peasant rebellion in Ise Province (the so-called Nagashima Ikko-Ikki), which had resulted in the death of his younger brother, Nobuoki. The campaign was successful at first, with several outlying forts being taken, but an attempt to secure the rebels’ main fortress at Nagashima failed, and Nobunaga was obliged to fall back after an ambush threatened to cut him off.

    A 19th-century depiction of the fighting in Nagashima.

    The year would end on a more positive note for him, however, as Ashikaga Yoshiaki, who was still claiming the title of Shogun, was forced to flee Wakae Castle (in modern Osaka) and retreat to Kii Province. In December, Nobunaga’s forces captured the important and wealthy Tamonyama Castle (modern Nara), further securing his territory in central Japan.

    1574 would bring new problems, starting with another peasant rebellion (the Echizen Ikko-Ikki) in territory that Nobunaga had only recently taken from the Azai-Asakura. Shortly after that, a renewed attack by the Takeda, now led by Shingen’s son, Katsuyori, invaded Mino Province. Nobunaga marched to meet them, but the border castles fell before he could arrive, and so he withdrew, avoiding a decisive clash with the Takeda for now.

    Takeda Katsuyori

    With crises in all directions, Nobunaga was stretched to his limit, but it was in moments like this where he showed his brilliance and his brutality. The Ikko-Ikki fortress at Nagashima had been a thorn in his side for years, and he set out to remove it in the summer of 1574, surrounding the fortress from land and sea and starving the defenders into surrender by September.

    It is said that some attempted to flee by boat, but Nobunaga stopped them with a volley of gunfire. Suitably provoked, the Ikko-Ikki launched a counterattack that ultimately failed, but killed Nobunaga’s half-brother. In response, Nobunaga had the remaining 20,000 defenders, including women and children, locked up inside the castle, which he then ordered burned.

    With Nagashima subdued, Nobunaga turned his attention to the Takeda, who had launched a series of relatively small-scale invasions throughout 1574, and by April 1575, were besieging the Tokugawa-controlled fortress at Nagashino. What followed was one of the most heavily mythologised battles of the era, and even today, many of the details are open to debate, but what is not in doubt is that the Battle of Nagashino inflicted a mortal wound on the Takeda. They never again posed a serious strategic threat to Nobunaga’s ambitions.

    One of his other long-term enemies was the Temple of Hongan-ji, the spiritual centre of the widespread Ikko-Ikki movement. The movement had been severely weakened by the loss of Nagashima, and in late Summer 1575, Nobunaga crushed the Echizen Ikko-Ikki, further weakening Hongan-ji’s power. This turn of events allowed Nobunaga to establish a short-lived peace in the territory he controlled.

    Emperor Ogimachi (r 1557-1586) was Emperor for most of Nobunaga’s rise to power.

    In November 1575, Nobunaga was appointed Dainagon, and Ukone no Taisho, Chief Councillor, and General of the Right, respectively, positions in the Imperial court which established his position, and right to rule the country (in the Emperor’s name, of course) Around this time Nobunaga also began distributing territory and other titles to his followers on behalf of the Emperor, and it is from this point that historians generally agree that Nobunaga gave up the pretence of supporting the Ashikaga, and began eyeing the position for himself. In light of this, he officially recognised his son, Nobutada, as his heir and gave orders for the construction of a new fortress at Azuchi.

    It couldn’t last, however, and in Spring 1576 Ishiyama Hongan-ji was in arms against him again, supported by a loose coalition of powerful clans, and at least nominally acting on behalf of the exiled Shogun, Yoshiaki. Initial attempts by Oda forces to subdue Hongan-ji failed, but when Nobunaga himself arrived, he won a decisive victory at the Battle of Tennoji, and subsequently laid siege to the vast Ishiyama temple complex.

    This modern recreation shows that the Ishiyama Hongan-ji complex was more akin to a fortified town than a temple.

    Nobunaga might have hoped to repeat his success at Nagashima, but those hopes were to be dashed when a fleet from the Mori Clan destroyed the Oda blockade at the Battle of Kizugawaguchi in August 1576, ensuring that, for the time being, supplies would continue to flow into Ishiyama, and the siege would drag on.

    Meanwhile, in 1577, Nobunaga led an army into Kii Province and forced the surrender of the Saika Clan before withdrawing, only to then have to face a rebellion from the Matsunaga Clan in Ise Province, which was put down in characteristically brutal fashion, with the castle burned, and its occupants forced to commit Seppuku.

    This image depicts Matsunaga Hisahide at the moment of his death. The story goes that Nobunaga offered to spare him in exchange for a rare tea kettle. In response, Hisahide is supposed to have smashed the kettle to pieces before killing himself.

    From 1578 to 1580, Nobunaga was forced to contend with the powerful Mori Clan and their allies for control of Harima Province. Meanwhile, his vassal, Akechi Mitsuhide, successfully subdued the provinces of Tamba and Tango. In late 1580, Nobunaga forced the surrender of Arioka and Miki Castles, bringing the whole of Harima under his control.

    Meanwhile, the Second Battle of Kizugawaguchi in December 1578 reversed the strategic situation in the seas around Ishiyama (Osaka Bay), when the rebuilt Oda navy inflicted a decisive defeat on the Mori fleet, finally cutting Ishiyama off completely. The siege would last until 1580, however, and it would eventually take an Imperial Order to convince the leadership to surrender, in exchange for being allowed to leave.

    A semi-contemporary image of Ishiyama Hongan-ji during the siege.

    War was never far away, but as 1581 dawned, Nobunaga was stronger than any Daimyo had ever been, and it was seriously possible that if anyone were to bring an end to the Sengoku Jidai and reunite the country, it would be him. However, he still had a few more rivals to overcome first.

    The Battle of Nagashino had been a death blow to the Takeda, but as late as 1582, they were still clinging on, and now Nobunaga made the decision to end them once and for all. Gathering a force of some 100,000 and supported by his ally Tokugawa Ieyasu, Nobunaga invaded Takeda territory in early 1582. The campaign was almost too easy, as Takeda resistance crumbled almost immediately, forts often surrendered without a fight, or after only a token display of defiance, and many former Takeda retainers simply switched sides, or else ran away from the advancing Oda.

    A heavily stylised (and much later) depiction of the end of Takeda Katsuyori, whose death would signal the end of his clan.

    The Takeda eventually stood their ground at the formidable Takato Castle, but, despite its reputation, it was taken quickly, and what remained of the Takeda began to melt away. Eventually, Takeda Katsuyori and his son Nobukatsu were trapped at Tano (modern Tsuru, Yamanashi Prefecture) and forced to commit Seppuku, bringing an end to the Takeda line and any hope of resistance to Nobunaga.

    With the Takeda gone, Nobunaga took some time to reorganise the newly conquered territories, and then headed home through the lands of his ally Tokugawa Ieyasu, who laid on entertainments, refreshments, and accommodation, all purpose-built for Nobunaga’s visit.

    By Spring, Nobunaga was back at his base at Azuchi, from where he made plans to invite the Emperor for a formal visit, and rumours began that the court was about to appoint him Shogun, or else some other senior position. The exact nature of this appointment and Nobunaga’s receptiveness to it are unclear, as the sources don’t agree on whether anything was offered at all, let alone what Nobunaga said about it. The Imperial visit was supposedly arranged for the following year, but again, the sources are scant.

    During this brief period of peace, Nobunaga is supposed to have announced his plans to conquer Shikoku from the Chosokabe. One of his retainers, Akechi Mitsuhide, was apparently unhappy about this, as he had previously acted as an intermediary between Nobunaga and the Chosokabe. Mitsuhide was further agrieved when Nobunaga ordered him to provide entertainment for the visiting Tokugawa Ieyasu. The story goes that Nobunaga accused Mitsuhide of doing a poor job (rightly or not) and launched into a public dressing-down of Mitsuhide that ended (according to some sources) with a literal kick in the backside.

    A 19th-century imagining of Nobunaga publicly chastising Mitsuhide.

    Given the importance of public image in Japan, it is easy to see why Mitsuhide might have felt a genuine grievance over this treatment. There is also a story that Mitsuhide’s mother had once served as a hostage for a truce that Nobunaga had gone on to break, resulting in the poor woman’s death. Whilst some of these stories are poorly sourced at best, what is known is that by the summer of 1582, Akechi Mitsuhide had had enough.

    The First Unifier – Oda Nobunaga. Part Two.

    In June 1565, the powerful Miyoshi Clan launched a coup against the Shogun, Ashikaga Yoshiteru. In the Eiroku Incident (named for the era), the Miyoshi successfully killed Yoshiteru, and his brother, Yoshiaki, a rival claimant to the throne, fled the capital, seeking support from regional warlords.

    Miyoshi Yoshitsugu, one of the main leaders in the Eiroku Incident.

    Nobunaga was initially enthusiastic about supporting Yoshiaki and the Shogunate more generally. Sources aren’t clear about Nobunaga’s ambitions at this point, with some arguing he genuinely wanted to restore the Ashikaga, whilst others portray it as cynical politicking, with Nobunaga intending to replace the Miyoshi’s puppet Shogun with his own.

    Regardless, in the short term, military defeat limited Nobunaga’s practical aid, and it wasn’t until September 1568 that he formally recognised Yoshiaki as Shogun and dispatched an army to Kyoto to secure his accession to the throne. There was some resistance, but Nobunaga’s forces would prove triumphant, and Ashikaga Yoshiaki was installed as the 15th (and final) Ashikaga Shogun. It seems that Yoshiaki wanted to install Nobunaga as kanrei, or deputy, but he refused. Moreover, at this point, the Kyoto political community seemed to have viewed Nobunaga as little more than Yoshiaki’s general, rather than a political force in his own right.

    Ashikaga Yoshiaki

    In early 1569, Nobunaga once again proved his worth to the Shogunate by putting down an attempt by the Miyoshi Clan to restore their position in the capital. Shortly after that, Nobunaga issued the denchuonokite, or “Rules of the Palace”, which were a set of nine (with seven more added later) rules for the management of the Shogun’s court. For a long time, it was believed that these rules were the first clear example of Nobunaga imposing his will on the Shogunate, though later research suggests that Yoshiaki agreed to the rules, and it was only later that the relationship between the two men began to break down.

    Nobunaga seems to have intended to return to his own territories after the restoration, serving as a sort of enforcer for the Shogun. However, by this point, the Shogunate was at such a low ebb that he found himself obliged to become closely involved in the running of the government. It has been suggested that the issuing of the “Palace Rules” was part of wider efforts by Nobunaga to reinforce the Shogunate, whilst also reining in the tendency of the Shogun to use his remaining power arbitrarily, favouring his own supporters at the expense of powerful clans elsewhere, who, Nobunaga (rightly) worried, would then become enemies of the Shogun, and be extension, himself.

    Part of the original Palace Rules.

    It was not as though Nobunaga had any trouble finding enemies of his own. In the late 1560s, his forces invaded Ise Province, and in 1570, he led an army north to Wakasa Province to subjugate the Asakura Clan, who had defied him. The invasion went well, but when word reached Nobunaga that the Azai Clan, led by his brother-in-law, had betrayed him, he was forced to retreat.

    The reasons for this sudden betrayal have been much romanticised, with Azai Nagamasa sometimes portrayed as a principled opponent of Nobunaga’s tyranny, or else bound by a close alliance to the Asakura that trumped his loyalty to the Oda. Historians are still divided on the exact cause, but the betrayal was likely a combination of opportunism and genuine fear about Nobunaga’s intentions.

    Nobunaga’s army was defeated at the Battle of Kanegasaki, with Nobunaga himself forced to flee the field. It is said that he was only able to escape because of the rearguard action led by Kinoshita Tōkichirō, who would later be known as Toyotomi Hideyoshi, and who was rewarded with gold by Nobunaga upon his return to Kyoto.

    A later depiction of Hideyoshi in Nobunaga’s service. He first appears in records from the early 1560s, and by the time of Kanegasaki, he had earned a reputation as one of Nobunaga’s most capable subordinates.

    Sources disagree on exactly how severe the defeat was; some state that Nobunaga returned to Kyoto with just ten men, whilst others put his army’s losses at fewer than 1300, out of a total of 30,000. Both numbers may be true, and it would certainly explain why Nobunaga himself seems to have remained calm in the wake of the defeat, inspecting the Imperial Palace the day after he returned to Kyoto.

    Whilst Nobunaga had certainly been forced to retreat, the case for his army remaining largely intact is made by the fact that just a few months after Kanegasaki, he, along with his ally, Tokugawa Ieyasu, led a force of up to 40,000 men in a campaign against the Azai-Asakura, culminating in the Battle of Anegawa, which Nobunaga won, though he was unable to finish either the Azai or Asakura off, despite inflicting heavy casualties on both.

    Nobunaga was prevented from pressing his advantage by events elsewhere. In August, the Miyoshi raised an army in Settsu Province (modern Osaka). Around the same time, the Ishiyama Hongan-ji Temple (on the site of modern Osaka Castle), fearing Nobunaga’s expansionist ambitions, raised an army of its own.

    All this was combined with the ongoing conflict with the Azai-Asakura alliance, and in September, supporters of Ishiyama Hongan-ji launched a rebellion in Ise Province in which Nobunaga’s younger brother, Nobuoki, was killed (or forced to commit seppuku) Faced with all this, Nobunaga chose to leverage his power at court, and in December, an Imperial decree was issued, ordering all sides to stop fighting, which they duly did, saving Nobunaga in the short-term.

    Peace in the Age of the Country at War was only ever a fleeting thing, however. In February 1571, Nobunaga led an army of some 50,000 against the forces of Ishiyama Hongan-ji, resulting in one of his most controversial acts, the burning of Mt Hiei.

    A semi-contemporary image of the burning of Mt Hiei, showing Nobunaga’s forces cutting people down as they try to flee the flames.

    Mt Hiei is one of the most sacred sites in Japanese Buddhism, and in the late 16th Century, its monks were major political players in their own right, with influence at both the Imperial and Shogunate court, and an army of warrior monks to defend their interests. Nobunaga’s attack should be seen in this context, but it was also an incredibly shocking act, which outraged a Japanese political class that took its religion very seriously. One particularly outraged player was Takeda Shingen, who denounced Nobunaga and began a campaign against his ally, the Tokugawa.

    Whilst historians suggest that Shingen’s outrage over Mt Hiei was just a pretext, the invasion of the Tokugawa home province of Mikawa was a serious threat to Nobunaga’s position. Shingen was arguably the most formidable warlord of his time, and may well have proved more than a match for Nobunaga. He was certainly too much for Tokugawa Ieyasu, who was obliged to retreat and call on Nobunaga for help.

    Nobunaga dispatched a force of 3000 men to help, but they, along with the Tokugawa, were decisively defeated at the Battle of Mikatagahara in January 1573. Ieyasu himself barely managed to escape the disaster. In the aftermath, Nobunaga appeared vulnerable, so vulnerable that Ashikaga Yoshiaki, who had begun to chafe under Nobunaga’s regime, raised an army in opposition to him, presumably in the hope that Takeda Shingen was on his way.

    A 19th-century depiction of the Battle of Mikatagahara. If Takeda Shingen had lived long enough to take advantage of the victory, the outcome of the Sengoku Jidai might have been very different.

    Unfortunately for Yoshiaki, Shingen was dead. Though the circumstances of his death are still murky, it ended a serious threat to Nobunaga, perhaps the most serious threat, and he was able to focus his forces on Kyoto, where he swiftly forced Yoshiaki to make peace and resume his position firmly under Nobunaga’s thumb.

    Yoshiaski refused to learn his lesson, however, and a second rebellion broke out not long after, with Shogunate loyalists barricading themselves inside Makishima Castle, which Nobunaga swiftly took, sending Yoshiaki into exile, and effectively bringing an end to the Ashikaga Shogunate, once and for all. Historians debate whether the Shogunate actually ended at this time, as Yoshiaki continued to use the title, and would spend the next few years roaming Japan seeking support to overthrow Nobunaga.

    What is true, though, is that the Ashikaga, long in decline, would never rule from Kyoto again. There had been strongmen before, of course, but they had always ruled through puppet Shoguns, and the institution had remained largely intact. Nobunaga did away with that; though he would never take the title of Shogun for himself, from 1573 until his death, Nobunaga sat at the top of a very precarious pile.

    Nobunaga’s territory is in red, in the centre, surrounded by enemies, or opportunities, depending on your perspective.

  • Lords of the East, Part 4

    Lords of the East, Part 4

    Hojo Ujiyasu died in 1571, having lived a life in which he had seen the fortunes of his clan rise, fall, and then rise again. His son, Ujimasa, inherited a strong but still dangerous position. Almost as soon as his father had passed, Ujimasa sought to end the war with Takeda Shingen and reestablish an alliance against their mutual enemy, Uesugi Kenshin.

    Hojo Ujimasa

    Shingen, by now in control of Suruga and stronger than ever, agreed, and it didn’t take long for the Hojo and Uesugi to be at each other’s throats again. In 1574, Kenshin invaded the Kanto, but his attention was focused mostly on his conflict with the Takeda, closer to home, and this round of Uesugi-Hojo fighting ended after an indecisive battle at the Tone River.

    With Kenshin busy elsewhere, Ujimasa turned his attention back to the Hojo’s old enemy, the Satomi, invading Shimotsuke in 1576, and advancing deep into Kazusa the next year. The Hojo clearly had the military advantage, with a vastly superior army and much larger territory. Despite this, the terrain of Kazusa and Awa Province (in the south of modern Chiba) is difficult for military operations, and Hojo supply lines relied either on ships crossing Tokyo Bay, which was difficult even in good weather, or on taking the long way around through Musashi Province (modern Tokyo).

    Neither of these options was particularly appealing, and what was more, the number of troops that the Hojo would have needed to commit to ending the war decisively would have left their other frontiers unacceptably vulnerable. So, in late 1577, a peace agreement (the Boso Ichiwa) was reached, establishing the border between the two factions and arranging a marriage to seal the deal.

    Although the marriage would end within a few years, with the death of Ujimasa’s daughter, the peace held (more or less). This is demonstrated by the fact that when civil war broke out among the Satomi following Yoshihiro’s death in 1578, the Hojo did not intervene, even though it would have been to their advantage to do so. The peace would eventually come to an end in 1590, but we’re getting ahead of ourselves.

    Uesugi Kenshin, one of the Hojo’s most dangerous foes, also died in 1578, and Uesugi, much like the Satomi, quickly fell into infighting over who would succeed him. This time, the Hojo made some attempts to intervene, as Uesugi Kagetora, one of the candidates, was Ujimasa’s younger brother, who had been adopted by Kenshin as part of the earlier peace deal. Ujimasa’s support for his one-time brother seems to have been quite limited, however, as Hojo forces contented themselves with securing control over Kozuke Province before withdrawing.

    Takeda Shingen had died in 1573, and with the Uesugi and Satomi tearing themselves apart over succession, by 1578, Ujimasa might have been forgiven for thinking that he’d ‘won’ in the Kanto. Unfortunately for him, Shingen’s death led to the disastrous Battle of Nagashino in 1575, in which the Takeda clan’s power was broken, leaving the western approaches to the Kanto open to a new, and far more dangerous, player.

    Oda Nobunaga.

    Oda Nobunaga had risen from obscure origins in Owari Province (around modern Nagoya) to become the preeminent lord in the realm. Though his power was not yet completely unchallenged, by 1578, he was best placed to be the man who would unite the realm and end the Sengoku Jidai. With that in mind, Ujimasa reached out diplomatically, seeking to gain Nobunaga’s favour and perhaps arrange a marriage between the Oda and Hojo. Around this time, he also seems to have ‘retired’ and given control of the clan to his son, Ujinao, whilst in reality retaining actual power for himself.

    For his part, Nobunaga seems to have had little interest in a rapprochement with the Hojo, though his exact plans aren’t clear; it’s reasonable to assume that, much like the Takeda, Nobunaga viewed the Hojo as a rival to eventually be crushed. However, in the short term, he had more pressing concerns in the West, dealing with the powerful Mori Clan, and for now, the Hojo were left alone.

    With Nobunaga’s death in June 1582, everything changed. Taking advantage of the chaos, Ujimasa launched an attack against former Oda loyalists in the Kanto, securing control of the whole of Kozuke Province, and advancing into Kai, where he was met by another power seeking to take advantage of Nobunaga’s death, Tokugawa Ieyasu.

    Tokugawa Ieyasu

    The fighting didn’t go well for the Hojo, but neither side was committed to all-out war, so a peace was agreed upon, which saw Ujimasa’s son, Ujinao, marry Ieyasu’s daughter, Tokuhime. In 1583, following the death of the last Ashikaga Kanto kubo, Ujimasa took the title for himself, positioning the Hojo at the very top of the hierarchy in the Kanto.

    Not long after that, a successful campaign in support of allies in Shimotsuke Province brought the southern half of that province under his control, and Hojo territory reached its greatest extent. By some later estimates, the territory was valued at 2.4 Million Koku, and with control of several key rivers and coastal areas, the Hojo now dominated the political, military, and economic spheres within the Kanto.

    In 1587, the chaos that had followed Nobunaga’s death had come to an end, with Toyotomi Hideyoshi emerging as the ultimate winner. That year, he issued the Soubujirei or “General Peace Order” commanding that all Daimyo cease private wars, essentially bringing an end to the Sengoku Jidai, at least on paper.

    Toyotomi Hideyoshi

    The Hojo agreed to abide by this order, but there was one outstanding issue. During the fighting in Kai Province in 1582, the Numata Domain, territory of the Sanada Clan, had defied Hojo attempts to conquer it. Though the fighting had largely come to an end, the border remained undefined, and so Hideyoshi dispatched vassals to settle the issue.

    Hideyoshi’s decision was that two-thirds of the territory would go to the Hojo, and the remaining third would remain in Sanada hands. To confirm the arrangement, the powerful Numata Castle was handed over to the Hojo and peace was apparently agreed. However, shortly after this, the new lord of Numata arranged for the defection of nearby Nagurumi Castle, on the Sanada side of the border.

    The plot succeeded, and Nagurumi was handed over to Hojo forces without a fight. The problem was that this was a clear violation of the peace deal, and things only got worse when Ujinao denied any knowledge of the plot in a letter to Hideyoshi, attempting to present the capture of the castle as a fait accompli.
    Hideyoshi wasn’t about to accept that, and demanded that Ujimasa (retired, but still effective head of the clan) come to Kyoto to explain his clan’s actions.

    Ujimasa refused, and Hideyoshi took this as an act of open rebellion. In 1589, he ordered all lords to attack the Hojo as punishment for their defiance. Initial attacks from the Sanada clan were repelled by Hojo forces, but Hideyoshi was able to muster a force in excess of 200,000 men, and when the main attack began, it would be a fight to the death.

    The Odawara Campaign is deserving of a post of its own, I think, so we’ll leave it there for now.

  • (No longer) Lords of the Four Provinces

    (No longer) Lords of the Four Provinces

    Last time, we looked at how the Chosokabe rose from barely holding a single castle to becoming effective masters of the whole of Shikoku. In 1582, it had looked like they were about to be invaded and (probably) conquered by Oda Nobunaga, but his sudden death at the Honnoji Incident in June 1582 granted the Chosokabe a brief reprieve.

    Between 1582 and 1585, they completed their conquest of Shikoku, although exactly how much control they really exerted is still debated by historians, with some suggesting that Shikoku was conquered and pacified, but others making the case that Chosokabe control outside of Tosa Province was tenuous.

    Regardless of the nature of Chosokabe’s control of Shikoku, it would prove to be brief. In the spring of 1585, Hashiba Hideyoshi, fresh from defeating the last of his rivals to the mantle of Nobunaga’s successor, turned his attention to Shikoku. Hideyoshi ordered the Chosokabe to hand over Iyo and Sanuki Provinces, effectively ceding the northern half of Shikoku to him.

    Toyotomi Hideyoshi, who would eventually become master of Japan.

    The Lord of the Chosokabe, Motochika, tried to negotiate, offering just Iyo Province. Hideyoshi was not a man to be bargained with, however, and in response to what he saw as Chosokabe’s defiance, he dispatched an army of some 100,000 men under the overall command of his brother, Hidenaga.

    Shikoku was attacked from three sides: Sanuki and Awa by Hidenaga’s army, and Iyo by the Mori who had recently submitted to Hideyoshi and were keen for a chance to prove their loyalty. Attacked on multiple fronts and facing overwhelming numbers, the Chosokabe did not resist for long. At the end of July, after already having lost Awa Province, Motochika surrendered.

    The terms were harsh, but not as bad as they might have been. Hideyoshi allowed the Chosokabe to keep control of Tosa Province, but the other three were divided amongst Hideyoshi’s vassals. In 1586, the Chosokabe would join Hideyoshi’s invasion of Kyushu, and though the campaign itself would be successful, Motochika’s heir, Nobuchika, was killed in battle.

    Overcome with grief, Motochika is supposed to have tried to kill himself, only being dissuaded at the last minute by his vassals. Not long after this, he relocated the base of the clan to what is now Kochi Castle, and in 1588, he named his fourth son, Morichika, as the new heir.

    In 1590, the Chosokabe again went to war in the service of Hideyoshi, this time dispatching naval forces to attack the Hojo Castle at Shimoda with 10,000 men. The garrison of 500 held out for nearly two months, but it was eventually taken, and with it, the Chosokabe contribution to the wider Odawara Campaign came to an end.

    In 1591, Motochika moved his base from Kochi Castle to a position at Urado (still within the modern city of Kochi). Some sources say this was because of the unfavourable location of the first castle (it was prone to flooding), whilst others suggest it was a strategic move, with Urado serving as the main base of the Chosokabe Navy, which took part in Hideyoshi’s long and ultimately unsuccessful invasions of Korea from 1592-1598.

    In 1596, the San Felipe Incident occurred when a Spanish Galleon (the San Felipe, hence the name) was shipwrecked off the coast of Tosa and brought into the harbour at Urado. We’ll focus on this incident specifically in a later post, but the short version is that Motochika confiscated the remaining cargo of the Galleon, and when officials from Hideyoshi arrived in Kochi to take possession of the goods, the captain of the Galleon heavily implied that the presence of Christians in Japan was the precursor to a Spanish Invasion, explaining that that was how the Spanish had managed to conquer such a large part of the globe.

    Hideyoshi had initially issued orders expelling Christian priests from Japan in 1586, but it had been unenforced before now. When news of the supposed Spanish invasion reached him, Hideyoshi was horrified, and in 1597, he had 26 Christians (including one passenger from the San Felipe) marched from Kyoto to Nagasaki (the centre of Christianity in Japan) and had all 26 crucified on a hill overlooking the city.

    A 19th Century depiction of the executions. The Japanese are wrongly portrayed with Chinese clothing and weapons.

    Motochika’s role in the persecution that followed is not clear, though Christianity had never been particularly strong on Shikoku, as the Chosokabe were largely opposed to foreigners in Japan, so it’s not hard to imagine he would have had no qualms about expelling them from his territory, even if he was not actively involved in the wider campaign.

    Hideyoshi’s death in 1598 would threaten the fragile peace he had forged, as his son and heir was just a boy, and a council of five regents was appointed to rule in his stead. Though Motochika was not a member of the council, he was still a man of influence, and in 1599, he was in Kyoto for an audience with Toyotomi Hideyori (Hideyoshi’s son) when he fell seriously ill.

    When it became clear that he wasn’t going to get better, he made his will, leaving control of the Chosokabe to his son Morichika, before he passed away in May that year. Morichika’s accession was far from smooth; he was unpopular amongst some of the Chosokabe’s retainers (apparently due to his arrogance and short temper), and the Toyotomi, de facto masters of Japan, didn’t recognise him as the new head of the clan.

    An early 20th century depiction of Chosokabe Morichika.

    Morichika would try to make good on his appointment by joining the Western Army (the pro-Toyotomi side) at the Battle of Sekigahara in 1600. This would prove to be an unwise choice in the end, as the Western Army was defeated by the Eastern Army under Tokugawa Ieyasu. Although the Chosokabe had not actually been involved in the final battle, they had chosen a side and would not escape the consequences.

    Morichika was punished by having Tosa taken from him. Though there would be some protest, the decision proved to be final, and the Chosokabe’s time as feudal lords was over. Motochika would campaign to have his territory restored until around 1605. In 1610, he supposedly became a monk, and although his movements around this time are unclear, by 1612, he was under direct surveillance from the new Tokugawa Shogunate.

    The new Shogun was right to suspect him, as, during the Osaka Campaign in 1615, he sided with the Toyotomi, hoping to secure the restoration of Chosokabe lands in Tosa. In the event, the Tokugawa would be victorious in that campaign, snuffing out the last of the Toyotomi Clan, and securing their rule.

    A contemporary kawaraban, a kind of early newspaper, depicting the fall of Osaka Castle.

    Morichika is reported to have fought bravely, leading an attack on the Tokugawa’s main camp that was ultimately unsuccessful, but which managed to inflict serious casualties on the Tokugawa army before being forced to withdraw. With Osaka Castle eventually falling to the Tokugawa, Morichika initially fled, but he was discovered and then humiliated by being paraded around Kyoto before being beheaded.

    Morichika’s death brought an end to the Chosokabe. Some sources state he had as many as five sons, all of whom died premature and violent deaths. Some other sources, however, suggest that he had just two children, a girl and a boy, one who married a local retainer, and the other who was whisked away after the Siege of Osaka and raised elsewhere. Unfortunately, in both cases, reliable sources are hard to come by, and the truth appears to be that the Chosokabe died with Morichika.

    The Chosokabe name would be revived in later years by descendants of Motochika’s brother, Chikafusa, who had been adopted into the Shima Clan years earlier and thus survived the end of the Chosokabe. The family survived in this form until March 2025, when the last head of the family, Chosokabe Tomochika, passed away childless, aged 82.

    「今は個人の時代。家を背負う時代ではありません。逆にこれからの世代が、自分の思いで新しい歴史を作っていくのも立派なことじゃないかと思いますね」

    “We are now in the age of the individual. It is no longer the age to shoulder the burden of a family. On the contrary, I think it is admirable for future generations to create a new history based on their own ideas.” – Chosokabe Tomochika

  • Memento Mori, Part 3

    Memento Mori, Part 3

    Last time, we looked at how the relationship between Mori Terumoto and Oda Nobunaga broke down, leaving both sides on the verge of conflict. After Terumoto declared for the Shogun, Ashikaga Yoshiaki (the last Ashikaga Shogun) declared that Terumoto would serve as ‘Vice Shogun’, a slightly ambiguous position which was rendered largely moot in practice, as the Shogun relied almost entirely on Mori’s strength of arms, reducing him to little more than a figurehead.

    Ashikaga Yoshiaki, the last of the Ashikaga Shoguns, and little more than a figurehead.

    The first action of this new ‘Shogunate’ (read: Mori) army was supporting the besieged warrior monks of Ishiyama Hongan-ji. You may recall in the post about the Ikko-Ikki, we mentioned Nobunaga’s campaigns against Hongan-ji, which ultimately lasted more than a decade, and left the temple a charred ruin.

    The Mori, possessing one of the most powerful navies amongst the Sengoku Daimyo, dispatched a fleet which made short work of the Oda forces in Osaka Bay, opening the way for supplies to be delivered to Hongan-ji. This victory prolonged the siege and gave the Mori unchallenged control of the Seto Inland Sea in the short term.

    Later that year, Nobunaga sought to restore the Amago Clan (long-time enemies of the Mori) to a position of strength, putting up Amago Katsuhisa, the last Amago ‘lord’ at Kozuki Castle, in Harima Province, hoping to attract Amago loyalists and any other opponents of the Mori, and make life difficult for Terumoto.

    A later image of Amago Katsuhisa, the last ‘lord’ of the Amago Clan.

    In response, Terumoto himself led an army to lay siege to Kozuki, and when a relief force, led by Hashiba (later Toyotomi) Hideyoshi, arrived, Terumoto handily defeated it, driving the Oda out of Harima Province, taking Kozuki Castle, and obliging the remaining Amago partisans to commit seppuku, which isn’t bad for a day’s work.

    Not long after this success, Terumoto would expand his influence in Harima still further, convincing several lords to defect to the Mori, and bottling up Nobunaga’s remaining loyalists in the province. After this series of successes, Terumoto had Nobunaga on the back foot, and in response, he pressured the Imperial Court to issue an order that Hongan-ji make peace with Nobunaga. The monks of Hongan-ji expressed a desire to make peace, but not without Terumoto, to whom they owed a debt of gratitude. In response, Nobunaga agreed and began negotiations with Hongan-ji and the Mori.

    The strategic situation shifted considerably in the early winter, however, as a Mori fleet dispatched to deliver further supplies to Hongan-ji was defeated by new ironclad ships of the Oda Navy. The exact nature of these vessels isn’t clear; the word ‘ironclad’ is a direct translation from Japanese, implying the vessels were at least partially armoured, though the exact style and extent of armour isn’t clearly recorded.

    An example of the type of warship used by the Mori Navy.

    Shortly after this victory, which drove the Mori beyond Awaji Island and opened Osaka Bay to the Oda, Nobunaga swiftly called off negotiations and made plans to continue the war. Despite the defeat, the Mori were still in a very strong position, however, and at this point, Terumoto made plans to advance on Kyoto and take the fight to Nobunaga directly.

    Plans were laid, including negotiation with Takeda Katsuyori for a simultaneous attack on Nobunaga’s ally, Tokugawa Ieyasu, and Terumoto set the date of the start of the campaign for early 1579. However, early 1579 came and went, and the Mori did not march. A series of rebellions broke out around the same time, supposedly instigated by both Nobunaga and the Otomo Clan (rivals to the Mori on Kyushu), and Terumoto had his hands full.

    The situation went from bad to worse for the Mori throughout 1579, as several border clans, angered at what they saw as a ‘betrayal’ when Terumoto failed to march on Kyoto, defected to the Oda side, disrupting communications with troops on the front line, and opening several gaps in Mori defences. The Mori failure to march also resulted in no further attempts to relieve Hongan-ji, and it was forced to surrender in early 1580.

    Not long after that, Nobunaga was able to focus significant forces on the Mori, and an army led by Hashiba Hideyoshi took advantage of the Mori’s weak position and launched a series of successful attacks against them, capturing castle after castle. A counter-attack in February 1582 led to a brief reprieve, but news from elsewhere was bad.

    A later artistic depiction of Toyotomi Hideyoshi (then still called Hashiba) around 1582.

    The Takeda, with whom the Mori had allied against Nobunaga, were decisively defeated in early Spring, and with their removal, Nobunaga turned his entire attention to the Mori. The situation was dire. A little more than five years earlier, the Mori had been a match for Nobunaga; indeed, had Terumoto marched on Kyoto, he would have had a good chance of success.

    Now, however, Nobunaga was stronger than ever, and internal rebellion, defections, and military defeats meant that the Mori were far weaker in comparison. Had Nobunaga advanced, he almost certainly would have won.

    As is so often the case, however, fate intervened. Nobunaga was betrayed by one of his generals in June 1582 and killed. His supporters immediately turned on each other, with Hashiba Hideyoshi, the man who had been leading the charge against the Mori, wishing to establish himself as Nobunaga’s successor, and so he concluded a swift peace with the Mori. For his part, Terumoto was glad to accept, even though it meant sacrificing three provinces. When news of Nobunaga’s death broke, Ashikaga Yoshiaki, still with the Mori, ordered Terumoto to march on Kyoto and take advantage of the situation.

    A 19th century depiction of Oda Nobunaga’s final moments.

    Terumoto refused, still forced to deal with internal rebellion, and although there would be plenty of opportunities to involve himself in the chaotic fighting that followed Nobunaga’s betrayal, the Mori would not move, instead adopting a ‘wait and see’ approach, which, in hindsight was wise, as although history would record Hideyoshi as the ultimate victor, in the summer of 1582, that was far from certain.

    One thing that Terumoto did agree to, however, was refusing to accept the ceding of three provinces to Hideyoshi as part of their peace deal. No doubt the Mori felt that Hideyoshi had misled them (Terumoto hadn’t known about Nobunaga’s death before the agreement), and with Nobunaga’s successors tearing each other apart, the Mori were in a good position to keep hold of their territory.

    Negotiations dragged on, even after Hideyoshi was able to win a decisive victory at the Battle of Shizugatake in April 1583, and he began to lose patience, threatening a resumption of war if the Mori didn’t concede. It would not be until early 1585 that a peace was actually agreed, and it was achieved largely without fresh fighting. The Mori would be allowed to keep seven provinces, representing much of the territory that had been taken by Terumoto’s grandfather, Motonari. In exchange, the Mori agreed to support Hideyoshi’s campaigns to unite the realm, especially in Shikoku and Kyushu, which the Mori assisted in invading in May 1585 and August 1586, respectively.

    Finally, in the summer of 1586, Terumoto formally became a vassal of Hideyoshi (by now known as Toyotomi), ending decades of conflict and proving to be a significant step in bringing the Sengoku Jidai to an end more generally. A testament to the new trust placed in the Mori came in 1590, when Hideyoshi attacked the Hojo Clan, masters of the Kanto. Though the Mori did not join the campaign, Mori troops were entrusted with guarding the capital while Hideyoshi was away.

    Around this time, Terumoto completed his new base at Hiroshima Castle and would take part in Hideyoshi’s ill-fated invasion of Korea in 1592. We will go into more detail about the events that followed later, but after Hideyoshi’s death in 1598, Terumoto was named as one of five regents for his infant son, Hideyori.

    The five regents were meant to stabilise the realm until Hideyori came of age, but it didn’t work; Tokugawa Ieyasu was swiftly opposed by the other four as it was believed (rightly as it turned out) that he wished to overthrow the current government and make himself Shogun. The tension would eventually lead to a new outbreak of violence, and a brief campaign culminated in the decisive Battle of Sekigahara in 1600.

    Teruhito and the Mori Clan were officially in opposition to the victorious Ieyasu, but had dispatched only a small force to Sekigahara, keeping their main strength at Osaka Castle to guard the heir. This was the strongest castle in the realm, and Terumoto had tens of thousands of fresh troops with which to hold it. Ieyasu, apparently aware of this, dispatched a letter to Terumoto, expressing his desire for positive relations between the two, and hoping that the Mori would depart Osaka without further violence.

    The walls of Osaka Castle as they appeared in 1865.

    Terumoto agreed when Ieyasu confirmed that the Mori would lose no territory in the aftermath. However, Ieyasu would almost immediately go back on his word once Terumoto was safely away from Osaka. The Mori were reduced to just two provinces in the far west, Suo and Nagato, and almost all the territory taken by Motonari and Terumoto was lost.

    Terumoto himself would officially retire as head of the clan not long after Sekigahara and became a monk, though in reality, he would retain most of the actual authority within the clan. One challenge that came about almost immediately was the loss of income that came with the loss of territory. Before Sekigahara, the Mori had had an income of more than 1 million koku (a Koku being approximately how much rice one man needed for a year). After Sekigahara and the loss of five of their provinces, this income was down to less than 300,000.

    This loss in income led to a loss in strength, as many of the clan’s retainers found their stipends reduced or lost entirely, leading them to seek employment elsewhere (just in case you thought Samurai were all about unquestioned loyalty.) Terumoto rather astutely recognised that this reduction might actually benefit the clan long term, as disloyal vassals would leave quickly, and even those who remained could be chosen based on ability, leading to a reduction in the clan’s overall strength, but perhaps improving skill and efficiency, at least in theory.

    A 19th century photograph of Hagi Castle, where the Mori Clan were based after their forced relocation.

    This would prove a wise move, as a land survey in 1610 showed that the Mori’s financial situation was better than originally assumed, and the reduction in vassals and retainers had led to a leaner, more efficient administration.

    Peace in the realm would last a while under Tokugawa Ieyasu’s rule, but it was a fragile thing. In 1614, the now adult Toyotomi Hideyori (Hideyoshi’s heir) brought about a crisis when a new prayer bell was inscribed with language that was interpreted as calling for the overthrow of the Tokugawa. Hideyori holed up in Osaka Castle and called on all ‘loyal vassals’ to come to his aid. Most, including Terumoto, ignored him, and when Ieyasu marched on Osaka, he requested the Mori dispatch their navy in support, which they duly did.

    Terumoto also led an army to Osaka, though the Mori would ultimately play a relatively small role in the so-called Winter Siege of Osaka. The following year, during what is called the Summer Siege, Ieyasu attacked Osaka again, this time successfully, capturing and executing Hideyori, and bringing his line to an end.

    Tokugawa Ieyasu, the man who would ultimately bring the Sengoku Jidai to an end.

    The Mori were again asked to dispatch an army, but delays in orders and the length of the march meant they arrived only after Osaka had fallen. There was some concern that this delay might be interpreted as treachery by Ieyasu; however, even the savvy political operator, Ieyasu, chose to lay the blame on slow communication instead, sparing the blushes of the Mori.

    Terumoto, his health failing and age catching up with him, handed full control of the clan over to his heir, Hidenari, in 1621, and although a formal system of ‘dual leadership’ would continue, it was becoming increasingly clear that Terumoto’s time was running out.

    He would continue to play a role in the affairs of the Mori until his death in 1625, and his clan’s distant position from the new capital in Edo afforded them a certain degree of autonomy, at least with regard to internal affairs, in the years that followed.

    That would prove important in the 19th century, as the arrival of American ships in Edo Bay forced Japan to end its period of isolation. It would be the Mori Clan, based in what by then was called the Choshu Domain, who would lead the charge against the Tokugawa Shogunate, overthrowing it, and re-establishing Imperial Rule in the so-called Meiji Restoration, but we are getting way ahead of ourselves.

    Mori Terumoto is one of the giants of the Sengoku Era. Building on the successes of his grandfather, Motonari, he led the Mori to a position in which they may well have been able to take power for themselves, had things gone a little differently. Ultimately, despite never gaining ultimate power for themselves, Terumoto and his successors would prove to be one of the success stories of this period, surviving the turmoil and even thriving in the new Japan of the 19th Century.

  • Memento Mori, Part 2

    Memento Mori, Part 2

    Last time we looked at Mori Motonari, the lord who took his clan from struggling to hold onto their domains to controlling one of the largest territories of any clan during the Sengoku Period. Motonari’s son, Takamoto, died early, and so it would fall to his grandson, Terumoto, to lead the clan after Motonari himself passed in 1571.

    Mori Terumoto

    Terumoto was born in 1553, at a time when his clan, the Mori, were already on the rise. Under the leadership of Motonari, the clan had recently purged the Inoue, who had presented a serious internal threat, obliging Motonari to get rid of them. Shortly before Terumoto was born, the Ouchi, nominal overlords of the Mori, were seriously weakened by an internal coup, allowing Motonari to expand his clan’s power base still further, and not long after that, the Mori would win the decisive Battle of Itsukushima, establishing themselves as the (relatively) unchallenged power in the region.

    Throughout his early life, Terumoto hardly saw his father or grandfather, as both men were frequently on campaign, and the young boy, as the future leader of the Mori, was kept safe, far from the fighting. Takamoto was, by this point, technically the leader of the Mori (though Motonari would remain in control), and when he died suddenly in 1563, Terumoto, just 11 years old, became the nominal head of the clan. Due to his youth, however, Motonari agreed to serve as ‘co-leader’, whilst (again) retaining all the actual power.

    In 1565, as a sign of how far the Mori had risen, Terumoto’s coming-of-age ceremony was attended by an official representative of the Shogunate, lending formal (if only symbolic) prestige to the young man. After this, Terumoto, who was now legally an adult, became the official head of the clan, and from then on, most legal documents carried his signature, though he would continue to defer to his grandfather in practice.

    Later that year, Terumoto would join his grandfather in Izumo Province, taking part in the campaign against the Amago, who had once been strong enough to demand fealty from the Mori, but were now on their last legs. This final campaign against the Amago would be concluded successfully in late 1566, with the surrender of their last stronghold at Gassan-Toda Castle, signalling the end of the war and the Amago Clan.

    Despite this victory, an uprising of former Amago retainers would occur in June 1569, followed by a similar uprising amongst former Ouchi warriors in October. These twin uprisings were either instigated or supported after the fact by the Otomo, whom the Mori had been fighting for control of Northern Kyushu with.

    Mori control of Izumo, Suo, and Nagato provinces was suddenly under serious threat. Withdrawing forces from Kyushu allowed them to quickly deal with the Amago rebellion, but the Ouchi proved a much sterner test, and required the Mori to dedicate even more resources to putting them down. Though victorious in early 1570, the consequences were that the Mori lost all their influence in Kyushu and had to continue a long, bloody campaign, trying to stamp out the embers of the Amago.

    Around this time, wider events began to have an impact on the Mori as well, bringing them onto the main stage of events in and around Kyoto. Earlier, in 1565, Shogun Ashikaga Yoshiteru was assassinated in what became called the Eiroku Incident, and his replacement, Ashikaga Yoshiaki, went looking for support from the clans further away from the capital.

    In 1568, the new Shogun dispatched a request for aid to several powerful leaders, including Uesugi Kenshin, Oda Nobunaga, and Mori Motonari. The Uesugi and Mori refused, but Nobunaga, based closer to the capital and possessing uncommon ability and ambition, responded positively and dispatched forces to Kyoto.

    Ashikaga Yoshiaki, the last of the troubled Ashikaga Shoguns.

    Not long after that, the Oda and Mori began to cooperate against their common enemy, the Miyoshi (who also happened to be the clan behind the assassination of the previous Shogun, which was handy). Over the next few years, an alliance would be established, and Nobunaga would actually dispatch forces to help the Mori put down the Amago and Ouchi, but beyond that, there would be little direct cooperation.

    When Mori Motonari died in 1572, leaving Terumoto to lead the clan alone, relations with Nobunaga were already in decline. Previously, the Mori had sought to use the authority of the Shogun (by now under Nobunaga’s control) to advance their own goals, and for a time, Nobunaga was happy to acquiesce, but after 1572, it became clear that Nobunaga had plans of his own that didn’t necessarily involve the Mori.

    Though the Shogun had largely been under Nobunaga’s control since 1565, at first, it had been a subtle arrangement. Nobunaga was in charge, but Yoshiaki was permitted to still act like the Shogun, even if his commands and proclamations (such as they were) were increasingly screened and eventually written by Nobunaga.

    Oda Nobunaga.

    Yoshiaki didn’t passively accept this, however. His problem was that he had little military strength of his own (a problem for the Ashikaga Shoguns since the very start), and with Nobunaga’s pre-eminent military position, the Shogun needed help. He thought he might find it in the Mori, one of the few clans that had the strength to challenge Nobunaga directly.

    In 1573, at the recommendation of the Shogun, Terumoto was granted the title of Uma no Kami, which translates as “Master of Horse”. Though Imperial titles had long since become little more than baubles, they still carried prestige, and Yoshiaki almost certainly did it to butter the Mori up and bring them over to his side, against Nobunaga.

    Yoshiaki was desperate by this point. Earlier that year, Takeda Shingen, who had agreed to march on Kyoto at least nominally in support of the Shogun, had died suddenly, bringing an end to the prospect of Takeda support. In early Spring, Yoshiaki raised an army anyway, hoping to take advantage of Nobunaga being distracted elsewhere, but instead suffered a series of defeats, which culminated in the Battle of Makishima Castle in July, which saw Yoshiaki exiled from Kyoto.

    Shortly after this, Nobunaga, aware of his vulnerable position, wrote to Terumoto, assuring him that it was the actions of the Shogun that led to Oda troops formally occupying the capital, and that he would do everything he could to maintain peace in the realm. Given that there hadn’t been peace in the realm for more than a century at this point, it leads us to conclude Nobunaga was just being polite.

    Though Terumoto probably eyed Nobunaga’s expansionism warily, the alliance was, for now, convenient for both sides, as it largely secured the border between the two powerful clans and allowed them to carve up the territory of the smaller clans caught in the middle. Terumoto did continue to try to mediate a peace between Yoshiaki and Nobunaga, though neither side seems to have negotiated with much faith.

    Scholars speculate that both Terumoto and Nobunaga wanted to avoid a situation in which the Shogun would flee to Mori territory, Terumoto because had no interest in helping Yoshiaki, but couldn’t rely on some of his more tenuous vassals not making trouble, and Nobunaga for pretty much the same reason, the Mori were one of the few clans strong enough to oppose him, and if they backed the Shogun, Nobunaga might be in trouble.

    Though Nobunaga was allied with the Mori, he took other actions that would be considered unfriendly. On the Eastern borders of Mori territory (the West, as far as Nobunaga was concerned) lay the Urakami Clan, who dominated the three provinces of Bizen, Harima, and Mimasaka. The Mori and Urakami had engaged in a long war before the Urakami had agreed to submit to the Mori in exchange for recognition of this territory, terms to which the Mori agreed, effectively turning the Urakami into vassals.

    Bizen Province
    Harima Province
    Mimasaka Province

    However, Nobunaga issued a “Red Seal Letter” (an official, legally binding document named for its eponymous red seal), recognising the Urakami as lords of the three provinces. This was, in effect, simply making official something that was already a fact; however, when the Urakami accepted the letter, they effectively ceased to be Terumoto’s vassals, that is, if the Mori accepted the new situation.

    The Mori, not surprisingly, did not. In 1575, they attacked the Urakami, defeating them in a series of battles and essentially eliminating them as a power, taking direct control of the provinces. The Urakami had apparently expected Nobunaga to dispatch forces to aid them, but he had erred on the side of caution, deciding that the Urakami were an acceptable sacrifice for keeping the peace with the Mori, at least for now.

    An immediate consequence of this was that there were no more buffers between the Mori and Oda territories, which now shared a border. The relationship was already tense, and it only grew worse as both sides became involved in Tajima Province. Expecting that Nobunaga would seek to make the province part of his domain, Terumoto made an alliance with the province’s local power, the Yamana. You may remember that name from earlier posts, and well done if you did; the Yamana were still around at this point, though no longer the great clan they once were.

    Then in 1576, the Shogun, Ashikaga Yoshiaki, having been forced to flee Kyoto by Nobunaga, found himself in Bingo Province, controlled by the Mori. Terumoto was not happy about this. Although he had ostensibly supported the restoration of the Shogunate, he understood that the only way that could happen was through war with Nobunaga, which he had no interest in. When the Shogun showed up on his doorstep and formally asked the Mori to support him in returning to Kyoto, then Terumoto was in a tricky spot.

    The Mori had promised Nobunaga that they would not harbour the exiled Shogun. On the other hand, Nobunaga had taken actions that were widely seen as trying to undermine Mori power, and although he had attacked them directly, the damage had been done.

    Terumoto, for his part, took a long time making up his mind. We’ll never know exactly what he was thinking, but it’s easy to imagine that Terumoto had plenty of reason to be wary of Nobunaga, who had already meddled in Mori affairs and would probably do so again if given the chance. The Mori were also one of the few clans with the power to actually face Nobunaga directly, something that Terumoto must have been aware of.

    Terumoto would declare for the Shogun in May 1576, effectively ending his alliance with Nobunaga and setting the Mori on a collision course with the Oda, but more on that next time.
