  • 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.

  • Lords of the East, Part 3

    Lords of the East, Part 3

    First post of 2026, so Happy New Year and thanks for sticking with me!

    The situation in 1560. The Hojo are in Green.
    By Alvin Lee – Own work, CC BY-SA 4.0, https://commons.wikimedia.org/w/index.php?curid=39200926

    By 1560, the Hojo were masters of much of the Kanto. A series of successful military campaigns over the previous decades had given them control over much of the area that now comprises modern-day Tokyo, Yokohama, and Chiba. Unlike today, when these areas are among the world’s most densely populated megacities, in the 16th century they were largely agricultural, with a few castle towns surrounded by vast expanses of farmland.

    It is also true that economic productivity, such as it was, was measured in rice production, with land being valued according to predicted rice output, though not necessarily actual output. In short, despite being a period of incredible violence, Japanese society relied almost entirely on rice production to function. Famine was a constant problem, and in 1560, the Hojo, despite controlling vast tracts of land, were experiencing just how bad a failed harvest could be.

    The so-called Eiroku Famine (named after the era) left the Hojo with no food or money, and military operations largely ground to a halt. It was a real blow then, when Uesugi Kenshin, at the head of an army of 8000 men, crossed the mountains in the North of the Kanto and invaded Hojo territory. Though the Uesugi army was relatively small, the Kanto region had been ruled by them for decades prior to the Hojo conquests, and when Kenshin appeared, dozens of local clans switched sides and flocked to the Uesugi banner.

    Uesugi Kenshin.

    Kenshin swept all before him; the Hojo lost castles in Kozuke, Shimosa, and Musashi, and by early 1561, the Uesugi had taken Kamakura. Then, at the head of an army that was reported to be 100,000 strong, Kenshin laid siege to Odawara, the Hojo capital. At this point, the Hojo were in real trouble, but fate was on their side. Ironically, the same famine that had left them seriously weakened now proved to be their saviour. An army of that size needs supplies, and there were few enough to be had in the Kanto, so it wasn’t long before the Uesugi began to melt away.

    The fortress of Odawara was one of the strongest in the realm, and with his army already shrinking, Kenshin faced a difficult choice. A long siege might fatally weaken his army, and even a successful assault could prove hugely costly. Then news arrived that his old enemy, Takeda Shingen, had invaded his home province, at the same time as stirring up a rebellion amongst the Ikko-Ikki, forcing Kenshin to return home post-haste.

    The Hojo had been saved by a combination of good luck and excellent timing on the part of Takeda Shingen, and despite their weakened state, Ujiyasu wasted no time in taking advantage of the reprieve. No sooner had Kenshin returned north than Hojo forces began the process of reconquering their lost territory. Most of the smaller clans that had joined the Uesugi now switched their loyalties back to the Hojo. This was a fairly common practice at the time; there were dozens, if not hundreds, of minor clans all over Japan who could never muster the strength to assert themselves against the power of a Daimyo, so their loyalty often proved to be a fickle thing, prioritising flexibility and survival rather than unquestioned loyalty.

    Takeda Shingen

    Not all the clans welcome the return of the Hojo, however, and Ujiyasu was obliged to dispatch armies to retake several castles in northern Musashi, and he won a decisive victory at the Battle of Mt Ikuno in November 1561, reestablishing the line of control along the mountains in the northern Kanto. Over the next two years, two sides form: a Hojo-Takeda Alliance on one side and a Uesugi-Satomi alliance on the other.

    The Hojo would generally have the better of the fighting in the Kanto, but would prove to be unable to advance further north, whilst the Uesugi would be a constant problem, but would struggle to make advances into the Kanto proper. By 1564, the conflict had largely become a stalemate, so Ujiyasu turned his attention to the East and the Satomi, whom he believed to be a weak link in the alliance.

    Though it might have been true that the Satomi were weaker than the Uesugi, they were no soft touch. When the Hojo crossed the Edogawa River on the way to invading Satomi territory, they were ambushed at the second Battle of Konodai and driven back with heavy losses. You may remember in the last post that the lord of the Satomi, Yoshiaki, had avoided the first Battle of Konodai by correctly identifying the weak position of his allies, retreating with his army intact.

    A later depiction of the area around Konodai.

    At the second battle, however, the command fell to Yoshiaki’s son, Yoshihiro, and he decided to celebrate his victory by distributing wine to his men. A party is a common way to celebrate any success, and the Satomi had successfully driven the Hojo back. The problem was that ‘driven back’ does not mean ‘defeated’; the Hojo regrouped and advanced again in the early hours of the following day.

    The Satomi army, now thoroughly inebriated, was no match for them, and Hojo forces forced the Satomi into a chaotic retreat that didn’t end until the Hojo banner was once again flying over most of Kasuza Province. Shortly after this campaign, Ujiyasu, who had already technically retired as lord of the Hojo in 1559, announced that he had fought his last campaign.

    After this, Ujiyasu seems to have largely limited himself to administration, leaving the business of war to his sons, though he would continue to play an important role in his clan’s future. In 1560, the Imagawa, one part of the triple Takeda-Hojo-Imagawa alliance, had been seriously weakened by the defeat at the Battle of Okehazama in 1560. By 1568, they were on their last legs, and Takeda Shingen, despite being a nominal ally, invaded the Imagawa’s home province of Suruga, aiming to take it for himself.

    Suruga Province

    The Hojo, seeking to support the Imagawa and prevent encirclement by a now hostile Takeda, dispatched an army under Hojo Ujimasa to relieve Suruga. At the same time, Ujiyasu engaged in diplomacy with the Tokugawa Clan, who had lands on the other side of Imagawa territory, and had poor relations with the Takeda. A joint attack by the Hojo and Tokugawa convinced Shingen that holding Suruga was impossible in the short term, and he retreated, with the Hojo moving in and taking large parts of eastern Suruga for themselves.

    Despite this success, the Hojo once again found themselves surrounded on three sides by hostile powers: the Takeda to the West, the Uesugi to the North, and the Satomi to the East. Ujiyasu correctly recognised that if he moved to deal with one threat, the other two would take advantage, and the Hojo did not have the strength for a three-front war. Therefore, he decided to make a formal peace with the Uesugi.

    This was unpopular on both sides because the Uesugi had been enemies of the Hojo more or less from the start, and that kind of bad blood isn’t easily forgotten. However, both sides had bigger problems, namely, Takeda Shingen. Though a ceasefire was agreed upon and the border between the two sides set, the consequences for the Uesugi were that many former allies in the Kanto, like the Satomi, felt betrayed and switched to supporting Takeda Shingen.

    This might not have been such a serious problem for the Hojo, because they were going to have fight the Satomi anyway, but in early 1569, the strategic situation shifted again, when the Takeda and Uesugi made a peace between themselves, meaning that Shingen could now focus his entire strength on the Hojo, whilst also relying on support from the Satomi, and other Kanto clans.

    An image depicting the legendary rivalry between Uesugi Kenshin and Takeda Shingen. Despite this, a peace between the two allowed Shingen to focus on the Hojo.

    Later that year, Shingen invaded Musashi Province and advanced south towards Odawara, the capital of the Hojo. Though they were able to lay siege to the mighty fortress, the chances of taking it were slim. The castle was one of the strongest in the realm, and Ujiyasu had made sure it was as well-defended as possible. Shingen likely understood that taking the castle would have been enormously costly, and he had better uses for his army, so he contented himself with burning the town around Odawara and retreating.

    Ujiyasu ordered his son, Ujimasa, to pursue the retreating Takeda, hoping to trap them before they could return to Kai Province. The plan failed, however, as the Takeda moved faster than expected and the ambush was discovered. At the ensuing Battle of Mimasu Pass, the Takeda successfully fended off the Hojo and returned to Kai.

    Some scholars believe that the whole attempt at Odawara had been an elaborate show of force, meant to impress Shingen’s new allies in the Kanto, or that it was a strategic move to keep the Hojo off balance whilst Takeda forces reinvaded Suruga. Either way, there doesn’t seem to have been much enthusiasm amongst either the Hojo or Takeda to continue the war, and some sources suggest that, shortly before his death, Ujiyasu told his son, Ujimasa, that he should return to a state of peace with the Takeda and make war on their traditional enemy, the Uesugi.

    Hojo Ujimasa

    Ujiyasu himself is supposed to have suffered a stroke in the summer of 1570. Sources from the time speak of him slurring his words or being unable to speak at all, and although he rallied briefly around the New Year in 1571, he would begin to decline again shortly afterwards. There are no official documents bearing his seal after May, and he would eventually pass away in October that year.

    Lords of the East, Part 2

    In 1537, Hojo Ujitsuna launched a successful invasion of Suruga Province, establishing the frontier at the Fuji River and ending the threat from the Imagawa-Takeda alliance, at least for now. Shortly after this news broke that (Ogigayatsu) Uesugi Tomoaki had died. Tomoaki had been an implacable foe of the Hojo, and his death severely weakened his clan, which was now led by the 12-year-old Tomosada.

    The Fuji River as it appears today, in modern Shizuoka Prefecture.

    It wasn’t all good news, however. With the bulk of the Hojo forces focused in Suruga against the Imagawa, forces of the Satomi Clan moved to expel the Hojo from the Boso Peninsula (modern Chiba), quickly establishing control and forcing the remaining Hojo loyalists to flee. There was little Ujitsuna could do about that in the short term, but in the summer of 1537, he gathered 15,000 men at Edo Castle before dispatching his son, Ujiyasu, to take the Uesugi stronghold at Kawagoe.

    The castle was taken undamaged after a surprise attack, and when the Uesugi tried to recapture it on New Year’s Day 1538, they were defeated. With his northern flank secure, Ujitsuna launched a campaign to reestablish control over the Boso Peninsula. Though they were initially successful, the attack clashed with the plans of the Koga Kubo, Ashikaga Yoshiaki.

    You may remember from earlier posts that the position of Kubo was the Shogun’s deputy in a given area. In decades past, the centre of the Kubo‘s power had been Kamakura, but the catastrophic decline of Shogunate power meant that the Kubo was eventually obliged to leave Kamakura (which was now under Hojo control) and take up residence at Koga, in Shimosa Province (modern Ibaraki).

    Yoshiaki had the long-term objective of reestablishing the Kubos’ preeminent position over the whole Kanto, and the Hojo stood in direct opposition to this. Both sides were about equal in strength, but while the Hojo were united behind Ujitsuna, Yoshiaki’s forces were united in opposition to the Hojo, but not necessarily in support of the Kubo.

    Though Yoshiaki’s forces agreed to challenge the Hojo at the Edogawa River, they couldn’t decide on a strategy. Yoshiaki’s allies suggested attacking the Hojo as they crossed the river, but sources say that Yoshiaki, proud of his illustrious Ashikaga name, refused such a strategy, deciding that he would march out in person and face the Hojo in the field, once the bulk of their forces were already across the river.

    Satomi Yoshitaka, once a supporter of the Hojo but now serving under Yoshiaki, recognised that the strategy robbed them of the advantage of the river and was reluctant to commit his forces to open battle with the Hojo, where victory was far from certain. Yoshitaka also recognised that if Yoshiaki were defeated, a large expanse of territory would become available; thus, he positioned his forces away from what he assumed would be the main battlefield, ready to retreat quickly if things looked to be going badly.

    Though heavily built up today, this hill was the site of some of the fiercest fighting at the Battle of Konodai.

    What became known as the Battle of Konodai began on the morning of November 8th, when the Hojo forces crossed the river. Initially, Yoshiaki’s forces had the advantage, but throughout the day, more Hojo forces arrived, and the tide of battle turned. When news came that Yoshiaki’s brother and son had been killed, he flew into a rage and charged the Hojo himself, only to be struck down by an arrow and killed. Seeing this, Satomi Yoshitaka withdrew his unengaged army, and shortly afterwards, the remaining forces began a retreat that swiftly turned into a rout.

    The Hojo used the momentum of victory to advance into Kazusa and Shimosa Provinces, whilst Yoshitaka, with his army still intact, would be able to take control of almost the entire Boso Peninsula, where he would continue to resist the Hojo, beginning a feud that would last decades.

    Although the exact date is unclear, after the victory at Konodai, Ujitsuna wouldn’t lead another campaign, and scholars agree that he retired as head of the clan sometime in 1539, when his son, Ujiyasu, completed the conquest of Shimosa and Kazusa Provinces. In late 1540, the reconstruction of Tsurugaoka Hachiman Shrine was completed, and Ujitsuna held a celebration there in which he was recognised as Kanto Kanrei, the Shogun’s official deputy in the Kanto, a title that reflected his preeminent position in the region.

    Hojo Ujiyasu.

    Ujitsuna would eventually pass away in August 1541, and his son, Ujiyasu, lord now in fact as well as name, inherited a strong but dangerous position. Successful campaigns in the east had extended Hojo control to Shimosa province. To the north, the Ogigayatsu-Uesugi plotted revenge and the return of Kawagoe Castle, whilst to the east, the conflict with the Imagawa dragged on, despite a strong frontier on the Fuji River.

    A famine in 1540-41 precluded an immediate campaign, and in 1542 Ujiyasu ordered a land survey, which enabled him to adjust and reform taxation in his territory (which was largely based on rice production) and to ensure a strong economic base for what was to come next. In 1545, the Imagawa sent out peace feelers, but no agreement could be reached, and the Imagawa joined forces with the Uesugi, with both agreeing to attack the Hojo from east and west.

    Ujiyasu rushed forces to the east, but a combined Imagawa-Takeda army proved too strong, and Ujiyasu was eventually obliged to conclude a disadvantageous peace, which saw him cede all the territory the Hojo had controlled in Suruga back to the Imagawa. Though the new border would remain tense, the peace held, and all three sides would eventually conclude an alliance in 1554, though we’re getting ahead of ourselves.

    A later image of Kawagoe Castle.

    Meanwhile, the Uesugi and their allies had massed a force of some 80,000 men around Kawagoe Castle, and with Ujiyasu busy in Surugu, the castle would endure a 6-month siege. Even after the Hojo had secured peace with the Imagawa, Ujiyasu could only muster 10,000 men, and what happened next is a matter of some debate.

    The most common telling is that Ujiyasu, in concert with the garrison inside the castle, organised a night attack on the Uesugi that caught them completely by surprise and routed them in a victory so complete that the Uesugi were destroyed as a serious force in the Kanto. The problem with this version of events is that the only sources describing the battle in that way come from the Edo Period, nearly 100 years after the events.

    Scholars debate the accuracy of those reports, and some suggest that the Battle of Kawagoe Castle happened in a very different way, or may never have happened at all, but what is certain is that the siege was lifted and either during the lifting, or shortly afterwards, the lord of the Uesugi, Tomosada, was killed, and the rest of the clan was forced north, leaving Musashi Province in Hojo hands.

    The remains of Hirai Castle.

    The war against the Uesugi would continue, however. In 1550, an attack on Hirai Castle was repulsed, only for a second attempt the next year to succeed, driving Uesugi Norimasa further north, where he sought refuge with Nagao Kagetora (better known to history as Uesugi Kenshin). In the east, too, the Hojo would advance, marching into Hitachi and Shimotsuke Province, and continuing the war against the Satomi of Kazusa Province to their southeast, conquering Kanaya Castle in 1555 and establishing Hojo control over almost the whole of the western Boso Peninsula.

    These conquests in the east were possible because of the peace established on the Hojo’s western borders. Though there was no actual fighting, the border remained very tense until the establishment of a triple alliance between the Imagawa, Takeda, and Hojo. This alliance was established over the period 1551-1554, as a series of marriages was arranged among all three parties, culminating in 1554, when Ujiyasu’s eldest daughter married Imagawa Yoshimoto’s eldest son, whilst Ujiyasu’s heir, Ujimasa, married the daughter of Takeda Shingen.

    This alliance secured the Hojo’s western border, and in 1559, Ujiyasu retired as head of the clan, handing formal power to his son Ujimasa while retaining actual control himself. That same year, he focused his full attention on pushing the last of the Uesugi clan out of Kozuke Province and established a strong presence at Numata to check any further Uesugi attempts to invade the Kanto.

    In 1560, the Imagawa suffered a serious and surprising defeat at the hands of Oda Nobunaga at the Battle of Okehazama, leaving the clan weak and the Hojo’s western flank reliant on the goodwill of the Takeda. During the same year, another outbreak of famine ravaged Hojo territory, severely weakening their economic power and food supply.

    The timing couldn’t have been much worse, because soon, the Uesugi, now led by Kenshin, would return to the Kanto, and the Hojo would face another serious crisis.

  • The Dragon of Echigo

    The Dragon of Echigo

    Much like Takeda Shingen, Kenshin’s real name wasn’t Kenshin, but Kagetora, with Kenshin being a religious name given in later life. However, as this is the name he is best known by, we will be referring to him as it throughout.

    Uesugi Kenshin, the Dragon of Echigo and the topic of this post.

    If you live your life in such a way that you earn the nickname ‘Dragon of something’ and have followers who think of you as an avatar of the God of War, then I’d say you’ve done pretty well for yourself. By this standard, our subject for today, Uesugi Kenshin, is a historical figure worthy of a closer look.

    Confusingly enough, Uesugi Kenshin wasn’t actually a member of the Uesugi family to begin with. He was a scion of the Nagao family, a strong clan who were vassals of the Yamanouchi branch of the Uesugi Clan, based in Echigo Province, in what is now Niigata Prefecture.

    Born in 1530, it is quite likely that Kenshin’s mother was a concubine, and what’s more, the boy himself was the second son. He was never intended to inherit control of the Nagao Clan, and he entered the temple at Risenji at age 11, apparently set on a life as a monk.

    He doesn’t seem to have stayed at Risenji for long, however, as when his father died in 1542, just a year later, he was at the funeral with armour and sword at his side, and shortly after that, he was at Tochio Castle when a rebellion against Kenshin’s brother (the new Lord Nagao) broke out. Despite being just 14, Kenshin is supposed to have led the defence of the castle and won his first victory.

    At the time, though the Uesugi were nominally the lords of the region, the Nagao served as deputy (and de facto) governors in their place. After the death of Kenshin’s father, it was his elder brother, Harukage, who inherited this position. The brothers don’t seem to have gotten along very well, however, and in the late 1540s, a movement emerged within the Nagao clan that sought to replace Harukage with Kenshin as head of the clan.

    Exactly why the clan was so against Harukage isn’t clear, but their efforts were ultimately successful. In 1548, under mediation from Uesugi Sadazane (their nominal overlord), Harukage agreed to adopt Kenshin, then retire as head of the clan, clearing the way for Kenshin to become head of the Nagao Clan aged just 18 or 19 (depending on the source).

    In 1550, Sadazane died without an heir, leaving Echigo Province without a lord. At this point, Shogun Ashikaga Yoshiteru instructed Kenshin to take the position of shugo of the province, effectively making him the new lord. Shogunate recognition was not quite the prestigious thing it had once been, however, and not long after this, supporters of Kenshin’s brother rose up in rebellion against him.

    Kenshin quickly bottled up the rebels at Sakado Castle, when the castle fell, the leader of the rebels was spared because he was Kenshin’s brother-in-law, and following this, Kenshin, still aged just 22 had established effectively control over the whole of Echigo Province.

    Looking back for a moment, five years earlier, the Uesugi Clan (or more accurately, the Ogigayatsu branch of the clan) had been defeated at the Battle of Kawagoe by the new rising star of the Kanto, the Hojo Clan. The Ogigayatsu-Uesugi were wiped out after this battle, leaving only the Yamanouchi Branch of the clan. In 1552, Uesugi Norimasa, who was, on paper, the Kanto Kanrei (Shogun’s deputy) was finally driven out of the Kanto entirely and sought refuge with Kenshin.

    A later depiction of Kawagoe Castle.

    Unsurprisingly, harbouring their enemies didn’t do much for the relationship between Kenshin and the Hojo, and Kenshin would send an army to oppose the Hojo’s invasion of Kozuke Province (modern Gunma Prefecture), capturing Numata Castle, and forcing the Hojo to retreat.

    A year later, Kenshin would face a new enemy, as Takeda Shingen’s long-running invasion of Shinano eventually obliged some of the clans there to flee and seek refuge with Kenshin in Echigo. Much like the Hojo, the Takeda didn’t take kindly to someone giving refuge to their enemies, and one of Japanese history’s most famous rivalries was born.

    In August 1553, an army led by Kenshin himself advanced against the Takeda in Shinan, defeating Shingen himself at the Battle of Fuse on August 30th, then again at Yuwata on September 1st. After this, Shingen adopted a strategy of avoiding direct battle with Kenshin, and the conflict settled into a stalemate that was later called the First Battle of Kawanakajima.

    In 1554-55, Kenshin was obliged to face a rebellion launched by treacherous vassals in league with Shingen. Putting down the rebellion quickly, Kenshin again marched into Shinano in April 1555 to face the advancing Takeda forces, again led by Shingen.

    At the Second Battle of Kawanakajima, the two sides faced each other in another stalemate, which dragged on for five months, before mediation from the Imagawa Clan led to both sides withdrawing after little actual fighting.

    In the following year, Kenshin apparently announced he would retire and become a monk, however, another outbreak of Takeda-backed rebellion forced him to change his plans, and after a period of peace, in 1557, Shingen again advanced against Kenshin’s allies in Shinano, forcing him to intervene and leading to the Third Battle of Kawanakajima, which, much like the previous two, swiftly settled into stalemate.

    A year later, Kenshin dispatched an army in an ultimately unsuccessful invasion of Kozuke Province and then in 1559 he was ‘invited’ for a meeting with the Shogun, Ashikaga Yoshiteru. Some sources say that Kenshin was granted the title of Kanto Kanrei at this time, the position traditionally held by the Uesugi Clan. He also apparently donated funds towards the maintenance and repair of the Imperial Palace.

    Swords supposedly gifted to Kenshin by the Emperor, photographed in 1928.

    It seems that Kenshin enjoyed good relations with the Shogunate, but the already well-established decline of the Shogun’s power is highlighted again when he asked Kenshin, Shingen, and the Hojo to make peace in order to combine their forces against the Shogun’s enemies. All three parties refused.

    In March 1560, the Imagawa Clan’s devastating defeat at Okehazama opened the way for Kenshin to intervene directly in the Kanto again, as the Imagawa had been allied to his enemies, the Hojo, and their defeat left the Hojo vulnerable. Later that year, Kenshin launched another large-scale invasion of Kozuke Province, driving the Hojo back and capturing several important castles before celebrating New Year at Maebashi Castle, the gateway to the Kanto Plain.

    In March 1561, Kenshin was formally adopted by the Yamanouchi-Uesugi Clan (the only remaining branch) and changed his surname to match. Though he would be known as Uesugi Kagetora from this point, we will continue to call him Kenshin to keep things simple.

    In August of that year, Kenshin led another large army into Shinano, and engaged the Takeda at the Fourth Battle of Kawanakajima. Unlike the previous three, this battle was not an extended stalemate, but a bloody one. Both sides suffered heavy casualties, with sources ranging from around 20% losses, to as high as 60 or 70%, and when the battle was over, the Takeda held the field, but made no attempt to intervene as the Uesugi withdrew, leading some to suggest the battle was a bloody draw.

    A legendary depiction of the Fourth Battle of Kawanakajima, depicting the (possibly apocryphal) moment that Uesugi Kenshin and Takeda Shingen met on the field.

    The Takeda and Hojo clans, recognising the Uesugi as their common enemy, renewed their combined efforts and launched a joint counter-attack in Musashi Province in late 1561. At first, Uesugi forces were successful against the alliance, even getting as far as besieging Odawara Castle, the Hojo’s main stronghold, before being forced to withdraw after allied counter-attacks in other parts of the Kanto.

    The strategic situation in the Kanto would ebb and flow over the following years, as Uesugi, Takeda, and Hojo armies advanced and retreated, and the local lords would switch sides depending on whoever appeared to be in the ascendancy.

    All three factions would be occupied with fighting each other, but also engaged in other battles and proxy wars with allies and supporters of each other’s enemies. For Kenshin, this meant being obliged to dispatch forces into neighbouring Etchu Province in 1568, to deal with Ikko Ikki forces nominally allied with Shingen.

    Etchu Province.

    Seeking to take advantage of this distraction, Takeda forces attacked in Shinano and were ultimately defeated, but a rebellion in Echigo (Kenshin’s home province) meant he was unable to take advantage of this victory in the short term.

    Later that year, the strategic situation would shift in Kenshin’s favour, however, as the long-term decline in Takeda-Imagawa relations finally led to open conflict between two of his main rivals. The Imagawa would request aid from both the Uesugi and the Hojo, and while Kenshin would refuse, the Hojo dispatched forces to oppose the Takeda, bringing an end to the alliance that had done so much to oppose Kenshin.

    However, years of expensive (and bloody) campaigns in the Kanto had left the Uesugi exhausted, and in 1569, Kenshin reluctantly agreed to a peace deal with the Hojo, which saw the Uesugi withdraw from Musashi Province (modern day Tokyo and Saitama) and the Hojo withdrew from Kozuke.

    With his borders with the Hojo (relatively) secure, Kenshin was able to focus on campaigning against the Takeda again. In 1570 and 1571, he would engage the Takeda and their allies in Etchu and Shinano Provinces, generally having the better of the fighting, but the situation would shift again in 1572 when the lord of the Hojo, Ujiyasu, passed away, and was replaced by Ujimasa, who made peace with the Takeda, turning on the Uesugi. At the same time, the Etchu Ikko Ikki launched a fresh attack, instigated by Takeda Shingen.

    Hojo Ujimasa, who reversed his father’s diplomatic policy.

    The Ikko Ikki would initially be successful against Kenshin, but by mid-1573, the momentum had shifted back in his favour, and several key fortresses within Etchu were taken. Also in that year, Kenshin’s long-time rival, Takeda Shingen, passed away, an event that apparently caused Kenshin to weep openly, but also significantly weakened the Takeda.

    Over the following two years, Kenshin was forced to split his focus between his ongoing campaign in Etchu and the situation in the Kanto. By the end of 1574, the Hojo had effectively ended any Uesugi presence in the region, and although Kenshin would launch counterattacks, the writing was on the wall for Uesugi power in the Kanto.

    In 1576, Kenshin would receive a request for aid from the Shogun, seeking support against Oda Nobunaga, who now dominated central Japan and had forced the Shogun into exile. In order to get to Kyoto, Kenshin was obliged to focus all his resources on securing Etchu and Noto Provinces. This campaign would drag on throughout 1576 and 1577, delayed by intervention from the Hojo and internal rebellion, but by November 1577, Kenshin had secured control of the provinces and was poised to strike at Kyoto itself.

    Mustering a large army, Kenshin would march out to meet a force led by Nobunaga’s generals, Shibata Katsuie and Hashiba Hideyoshi (better remembered to history as Toyotomi Hideyoshi), who were not fond of each other. A dispute led to Hideyoshi withdrawing his forces early, and when the two sides clashed at the Battle of the Tedori River on November 3rd, Kenshin would emerge victorious.

    The exact course of the battle, and even the size of the forces involved, is not clear from contemporary sources, but Kenshin would withdraw temporarily, issuing instructions for a renewed campaign to begin in the spring. The battle at the Tedori River had opened a strategic opportunity for Kenshin, and it has been speculated that he might have been able to complete his march on Kyoto.

    Much like his rival, Shingen, however, Kenshin would never make the march. In early March, Kenshin would collapse (allegedly whilst in the toilet) and fall into a coma from which he would never wake up; he died on March 13th, aged 49.

    Much like the Takeda after the death of Shingen, the Uesugi would be seriously weakened by Kenshin’s death. Though they had been a threat to Nobunaga, Kenshin’s death, and the ongoing effects of years of more or less constant conflict, rendered them powerless to stop the rise of Nobunaga, and after his death in 1582, the Uesugi would make their peace with his successors.

    Decisions made at the end of the Sengoku Jidai would see the clan’s star fall even further, though that is a story for another time.

  • The Kyotoku Rebellion

    The Kyotoku Rebellion

    Historians disagree on when the Sengoku Jidai actually began, with the Onin War being a common origin point. The other possibility is our subject today, the Kyotoku Rebellion.

    You may remember that the Kanto, the area in and around modern Tokyo, was not directly ruled from Kyoto. Instead, a member of the Ashikaga Family (from a different branch to the Shogun’s line) served as the Kamakura Kubo, a governor who effectively ruled independently from Kamakura, the capital of the previous Shogunate.

    The kubo didn’t rule alone, however, he was nominally supported by the Kanto Kanrei, the Shogun’s direct deputy in the region, a position that was supposedly subject to direct appointment by the Shogun, but had in reality become a hereditary title of the Uesugi Clan.

    Both positions were supposed to be loyal to the Shogun in Kyoto, but within a few years, that had become a legal fiction. The Kubo was formed in 1349, and for a while, records show them deferring to the central government in most things, especially the all-important appointments of provincial governors (shugo).

    We’ve covered the details of the individual flashpoints in earlier posts, but to recap very briefly, in 1416, 1438, and 1440, there was a series of escalating conflicts that pitted the kubo against the Shogun. After 1440, the Shogun, at this point Ashikaga Yoshinori, sought to take control of the Kanto directly, and the Uesugi were happy to oblige. The position of kubo was abolished, and the Uesugi ruled with an iron fist, certain of the Shogun’s support.

    Ashikaga Yoshinori, who supported the Uesugi in the Kanto.

    This support largely relied on the Shogun being alive, however, and when Yoshinori was assassinated in 1441, the situation in the Kanto grew tense very quickly. In response, the Shogunate government acquiesced to a petition from several Kanto lords, requesting a new kubo.

    This was granted, and Ashikaga Shigeuji was appointed in 1449. This, however, did not please the Uesugi, especially after Shigeuji began to distance himself from working with them, favouring the clans that had supported his father, Mochiuji.

    In April 1450, things came to a head when supporters of the Uesugi attacked the kubo at his residence in Kamakura. Caught by surprise, the kubo was forced to flee to nearby Enoshima, where he regrouped and defeated the Uesugi forces when they pursued him.

    Although the head of the Uesugi (and kanrei), Noritada, had not been directly involved in the attack, he took responsibility and was confined to house arrest. It was at this point that a new problem arose. As I mentioned, prior to 1440, the kubo had operated largely independently of the Shogun, but after the position was restored, the central government intend to keep Kamakura on a much shorter leash.

    Part of this leash shortening involved the insistence that any formal request to the Shogun required the signature of both the kubo and the kanrei. The problem now was that Noritada was under house arrest, and in an uncooperative mood, effectively leaving Shigeuji with no way to (legally) govern.

    Shigeuji was eventually forced to release Noritada, but the conflict between the two would only get worse. On the one hand, Noritada was head of the powerful Uesugi Clan, and kanrei, appointed by the Shogun, and his goal was to preserve the power and dignity of his family and their position in the Kanto.

    Shigeuji, on the other hand, appears to have had more personal reasons. Although there’s no doubt his position as kubo required a certain ruthlessness, sources from the time suggest that Shigeuji blamed the Uesugi for the death of his father, and he was consumed by a desire for revenge.

    A 19th century depiction of Shigeuji.

    So it came to pass, in December 1455, Shigeuji issued orders summoning Noritada to his residence. There’s a fair amount of speculation as to why Noritada would agree to go, given that it appeared to be an obvious trap, but go he did, and shortly after he arrived, he was cut down by men loyal to Shigeuji.

    This assassination was accompanied by similar acts across the Kanto, as Shigeuji’s supporters moved to cut the head off the proverbial snake. The Uesugi Clan was vast, however, like most major clans, it had branches all over the country, and Noritada’s brother and heir had actually been in Kyoto when he was assassinated, meaning that his succession as kanrei, at least on paper, went off with minimal interference.

    The other branches of the Uesugi Clan were enraged by Noritada’s death, and it wasn’t long before the new kanrei was able to gather an army and establish himself at Hirai Castle in Kozuke Province (modern Gunma Prefecture). When they marched against Kamakura, however, they were defeated at the Battle of Bubaigawara in modern-day Fuchu.

    The Uesugi were forced to retreat and ended up under siege at Oguri Castle, in modern-day Ibaraki Prefecture, and a long way from Kamakura. This proved to be a problem for Shigeuji, for although he was able to take Oguri Castle, forces sent by the Shogunate (who were none too pleased about Shigeuji’s actions) took Kamakura from behind (stop laughing), cutting the Kamakura Kubo off from Kamakura. From then on, Shigeuji would base himself at Koga Castle and became known as the Koga Kubo. We’ll just keep calling him kubo, though.

    The modern day remains of Koga Castle.

    The war between the Kanto’s two most powerful figures naturally led to utter chaos. Although both the kanrei and kubo could command the loyalty of thousands of warriors, the reality was that, with central power non-existent, rival clans took to settling their own affairs, usually at swordpoint.

    With neither side able to establish control, the Shogun dispatched his brother, Ashikaga Masatomo, to the Kanto in December 1457, officially to be the new Kamakura Kubo. This didn’t work as planned, however, Masatomo only had the power his brother would allow him, and the Kanto lords knew it.

    It got so bad that Masatomo couldn’t even take up residence in Kamakura and ended up at Horikoshi, in modern-day Shizuoka Prefecture. This situation led to him being called the Horikoshi Kubo, another would-be master of the Kanto who wasn’t even strong enough to demand his original title.

    Things got even worse when the Shogun attempted to launch a punitive expedition against Shigeuji. Even before the forces were properly gathered, the leader of the army, a member of the Shiba Clan, was expelled from his post after dispatching troops from the expedition to his own province (far to the north of the Kanto) to deal with private battles there.

    With the debacle of the expeditionary force, any hope for a decisive end to the war was lost, and the two sides got bogged down in back-and-forth skirmishes, sieges, and other militaristic shenanigans, with the (very loose) border being the Tone River, in the central Kanto.

    A later depiction of a canal entering the Tone River

    This would go on for ages, one side would gain the advantage, only to lose it again later and then suffer counter-attacks that would be themselves defeated. In 1466, the kanrei was killed in battle, and Shigeuji’s forces were briefly in the ascendance, but the Uesugi would recover, and in 1468, they would launch several successful counterattacks, and later, in 1471, they would even capture Shigeuji’s base at Koga.

    You might think that Shigeuji would be on the ropes, but no, he struck back, recaptured Koga, and the war dragged on, and on, and on. Just as the Onin War destroyed central authority in and around Kyoto, the Kyotoku War, which had now raged for 16 years, did the same in the Kanto.

    Then, in 1478, after 21 years of war, the Uesugi, suffering a major internal rebellion, were compelled to seek peace with Shigeuji, and the kubo, facing problems of his own, agreed. This ended the main phase of the war between the major powers, but did not bring peace to the Kanto, as both the Uesugi and Shigeuji turned to dealing with internal matters, putting down rebellions and forcing obedience from their erstwhile vassals, which is rarely a peaceful process.

    A final peace would be agreed in 1483 (yes, five years after the initial proposals), and Shigeuji was allowed to continue as kubo; however, he was forced to hand over Izu Province to Masatomo, who continued as Horikoshi Kubo.

    I’m sure, if you think about it for a moment, having two kubo in the Kanto region was never going to last, and it didn’t. Shigeuji had the authority and military power, but Masatomo had the legitimacy of Shogunate support; it was not a recipe for stable and secure government.

    While the fighting had been going on in the Kanto, the Onin War had started and ended (1467-77), and Shogunate authority was effectively at an end. This meant that actual support for Masatomo was minimal, and historians suggest that the only reason Shigeuji and the Uesugi agreed to peace was due to exhaustion after nearly 30 years of war.

    Despite the agreement, peace would not last in the Kanto. By the end of the 15th century, as with the region around Kyoto, the Kanto had fractured into rival territories controlled by numerous warlords. The Uesugi were initially in the strongest position, but by the time Shigeuji died in 1496, that was changing, and new powers were rising in the Kanto, but that’s a story for another time.

  • Kanto, Won’to

    Kanto, Won’to

    As we discussed last time, the relationship between the central government in Kyoto and the Kamakura Kubo, the regional military governor, was often quite strained. The decentralised nature of political power in Japan meant that, whilst the Kubo was nominally subordinate to the Shogun, they often acted as semi-independent rulers.

    The power of the kubo was, in theory, checked by the Kanto Kanrei, the Shogun’s direct deputy in the Kanto Region, who had, for decades by this point, been a member of the Uesugi Clan.

    Like most Samurai families, the Uesugi weren’t a single family, but a loose affiliation of siblings, cousins, and other relatives that shared a name and some common ancestry, but little else, with different branches of the Clan cooperating and opposing each other as the situation demanded.

    The strongest branch of the family at this point, and the one holding the position of Kanrei, was the Yamanouchi Uesugi, so named because of their residence in an area of Kamakura called, you guessed it, Yamanouchi. This particular branch of the family actually took over the position from the branch which had risen in rebellion in 1416 and been defeated.

    The Kanrei in the 1430s was Uesugi Norizane. He found himself in a fairly unenviable position. Although the kanrei was officially the subordinate of the Kamakura Kubo, the Shogun in Kyoto had the final say over who would actually hold the position, meaning that, in practice, the kanrei often found himself beholden to the will of the Shogun over that of his direct superior.

    This was probably fine at a time when Kamakura and Kyoto were in agreement, but by now, this was definitely not the case. As we talked about briefly last time, the Kamakura Kubo, Ashikaga Mochiuji, often followed an independent path, and this defiance led to a serious breakdown in his relationship with the Shogun.

    In 1429, the accession of a new Emperor called for a change in the Era name. This was (and arguably still is) a big deal in Japanese culture; whenever a new Emperor ascends the throne, the Era name is changed. It can also be changed after significant or otherwise tragic events, as those in power seek to figuratively draw a line under the past.

    Emperor Go-Hanazono, whose accession brought about the Era name changed that provoked the showdown between Mochiuji and the Shogun.

    A change of era is often an administrative formality for most, but this time, Mochiuji, being the independent-minded fellow that he was, apparently refused to adopt the new era name. This might seem like a petty decision to us, but it was, in effect, Mochiuji announcing to the world that he didn’t recognise the new era, and by extension, the new Emperor.

    Things got worse following the death of Shogun Yoshimochi in 1431. Mochiuji had expected to be called upon to be the next Shogun, as Yoshimochi had died without heirs. When Ashikaga Yoshinori, a monk, was selected instead, Mochiuji was angry enough to consider marching on Kyoto.

    This is where Uesugi Norizane rejoins our story. He dissuaded his hot-headed master, and no force was sent. In addition, he arranged for formal apologies regarding the Era change and even went so far as to return lands that had been confiscated by Mochiuji to the Shogun.

    Norizane is also recorded as having sent expensive gifts to Kyoto in an attempt to smooth over the considerable animosity that had built up towards Mochiuji there. Norizane was evidently trying to steer a moderate course; he owed his position to the Shogun, but he was nominally subordinate to the Kubo. When these two masters were in opposition, Norizane found himself caught in the middle.

    In 1436, his position got even worse. That year, fighting broke out in Shinano Province between rival factions seeking control of the province. One side called on Mochiuji for help, and he was eager to go, but Norizane intervened, pointing out that Shinano was not one of the provinces that were under the authority of the Kamakura Kubo. Thus, no forces were sent.

    The warlord who had requested Mochiuji’s help was defeated, and in 1437, Mochiuji planned to raise an army and march into Shinano anyway, presumably to avenge his fallen comrade. This time, however, rumours spread that the army was actually to be sent against Norizane.

    Things quickly got out of control after that. Although there was some attempt to negotiate, Norizane fled the Kanto entirely, retreating to the Uesugi stronghold in Echigo Province. There was a brief reconciliation in 1438, but things broke down again quickly afterwards, with Norizane resigning as kanrei.

    This time, Norizane fled to Kozuke Province, and Mochiuji sent an army after him. In response, Norizane called for help from the Shogun, and Yoshinori, who had been waiting for an excuse to deal with the troublesome kubo, readily agreed.

    A coalition of Kanto warlords loyal to the Shogun was assembled, and the Shogun used his influence at court to have an Imperial Banner issued to the army, effectively turning it into an Imperial army, and all those who opposed it into rebels against not only the Shogun but the Emperor himself.

    What impact this had on the morale of Mochiuji and his men isn’t clear, but throughout September and October 1438, their forces were repeatedly defeated, until eventually Mochiuji surrendered and attempted to become.

    Uesugi Norizane, continuing his policy of moderation, pleaded for Mochiuji’s life, and for his son to be allowed to take the position of Kubo. Shogun Yoshinori, however, was in no mood. Mochiuji had been a thorn in his side for decades, and he would not pass up the opportunity to deal with him.

    Mochiuji and his son were forced to commit suicide, and the position of Kamakura Kubo was temporarily abolished. That wouldn’t last long, though, and in 1440, Yoshinori attempted to have his own son appointed as the new kubo.

    This didn’t sit well with former loyalists of Mochiuji, and a rebellion, led by the Yuki Clan, broke out in the same year, with the stated aim of restoring one of Mochiuji’s sons to their late father’s position.

    In April 1441, the rebellion was defeated, and Mochuji’s surviving children were brought to Kyoto. Yoshinori continued his plans to appoint his son as kubo, but then fate took a turn, as it so often does.

    In June 1441, Yoshinori was invited to a banquet at the residence of the Akamatsu Clan, officially to celebrate the Shogun’s recent victory. When he arrived, the gates were locked, and he was set upon by a band of armed men and cut down.

    The immediate motive of his killer appears to have been either revenge for the confiscation of family property earlier in his reign or the fear of being politically purged. Historians speculate that Yoshinori was becoming increasingly paranoid, with the Imperial Nobility and Samurai class becoming fearful of the possibility of being denounced and facing exile or execution.

    A phrase used by contemporaries to describe this period of Yoshinori’s reign is ‘万人恐怖’ Bannin Kyofu, or Universal Fear, which gives you a good idea of the mood.

    In the immediate aftermath of the killing, rumours of a wider conspiracy abounded, but it soon became clear that the Akamatsu Clan had acted alone; the government’s attention focused on who would be the next Shogun. The most appropriate choice was Yoshinori’s son, Yoshikatsu, but he was just a boy, and it wasn’t until November 1442, 18 months after his father’s death, that Yoshikatsu was elevated to Shogun, despite being just nine.

    With Yoshinori’s death and his replacement by a boy, the strong, often dictatorial power of the Shogun was significantly reduced. Yoshikatsu would rely on a council of powerful lords to handle the realm until he came of age, but that didn’t happen, as Yoshikatsu fell in and died in July 1443, only eight months into his reign. His sudden death led to the spread of several rumours, from a fall from a horse to assassination, but historians generally believe he died of illness, possibly dysentery.

    Yoshikatsu was replaced by his brother, Yoshimasa, who was even younger, and he wouldn’t be officially declared Shogun until 1449, by which time real power had shifted from the Shogunate to several powerful clans.

    Though no one knew it then, the Ashikaga Shogunate had begun what would prove to be a terminal decline.
