    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.

    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.

    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.

    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.

    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.
