  • The Third Unifier – Tokugawa Ieyasu. Part Three.

    The Third Unifier – Tokugawa Ieyasu. Part Three.

    After the disastrous Battle of Mikatagahara in January 1573, contemporaries might have been forgiven for thinking that Tokugawa Ieyasu was finished. His army had been defeated and scattered, several important fortresses had fallen, and Takeda forces were camped deep inside his home province of Mikawa.

    The Battle of Mikatagahara was a disaster from which Ieyasu might not have recovered.

    Fate, however, was on Ieyasu’s side. Though Mikatagahara had been a catastrophe, the Takeda would prove unable to take advantage of their victory. Not long after the Battle, Takeda Shingen, arguably the most formidable warrior of his day, fell ill (some sources say he was wounded in battle, though later stories of Ninja assassinations are likely mythological).

    With their leader bedridden, the Takeda campaign stalled. They tried to keep the full extent of his illness secret, but when Shingen died in May, the once-mighty Takeda army began a full retreat from Mikawa. The Art of War writes that a general should know his enemy, and Ieyasu, student of war that he was, seems to have realised that something was amiss.

    Under Shingen, the Takeda were aggressive and highly capable, but after his (still secret) death, Ieyasu identified several weaknesses and launched a counter-attack, the success of which effectively confirmed his theory that Shingen was gone. With the momentum swinging back towards the Tokugawa, several clans that had defected to the Takeda switched sides again, and Ieyasu was able to swiftly regain the strength lost at Mikatagahara.

    Shingen’s successor, Katsuyori, has been remembered as a poor imitation of his father, though much of what was recorded about him was written by his enemies. In the short term, however, Katsuyori and Ieyasu were fairly evenly matched, and throughout 1574 and into 1575, they traded blows, with the momentum shifting back and forth.

    Ieyasu had something that Katsuyori didn’t, however, a powerful ally. The death of Shingen had removed a serious (possibly existential) threat to the ambitions of Oda Nobunaga, and in 1575, he was finally able to dispatch significant forces to support Ieyasu’s ongoing campaign against the Takeda.

    In early 1575, Takeda forces once again advanced against Mikawa province, laying siege to the strategically important Nagashino Castle. Sources suggest that the Takeda invested the castle with 15,000 men, whilst the defenders numbered only 500. Despite the disparity in strength, the fortress was situated in terrain that made it difficult for the Takeda to bring their full forces to bear, and for a time, the garrison held out.

    The situation changed dramatically, however, when the garrison’s food supplies were burned. In response, a messenger, Torii Suneemon, slipped through Takeda’s lines and made it to a combined Oda-Tokugawa army that was supposed to have numbered some 38,000 men (30,000 Oda and 8,000 Tokugawa, which goes some way to demonstrating the power dynamic in this ‘alliance’.)

    Suneemon then tried to return to Nagashino to inform the garrison that help was on the way, but he was instead captured by the Takeda. Katsuyori offered him a deal: if he told the garrison that no help was coming, he’d be set free. Instead, Sunemon shouted that relief was on the way, and the garrison should hold out, for which he was crucified in full view of the walls.

    A later (and somewhat dramatised) depiction of Suneemon exhorting the garrison of Nagashino to keep resisting.

    When the Oda-Tokugawa forces arrived two days later, the garrison was still holding out, and the Takeda turned to give battle. Although the Battle of Nagashino is one of the most famous and decisive battles of the Sengoku Jidai, scholars disagree on what actually happened. Nagashino has long been famous for Nobunaga’s innovative use of massed firearms, with thousands of foot soldiers firing in a three-rank system that kept up a constant hail of fire that decimated the Takeda’s famous cavalry charge.

    The exact number of firearms and the tactics used are still debated, but what is known for sure is that Nagashino represented a blow to the Takeda Clan from which they would never recover. In the aftermath, both Ieyasu and Nobunaga moved to take advantage, extending their control over Suruga and Totomi Provinces, and boxing the Takeda up in their traditional home in Kai and Shinano Province (modern Yamanashi and Nagano prefectures)

    Though Ieyasu had been on the winning side, the victory over the Takeda would mark the time when his relationship with Nobunaga ceased to be an alliance of equals. There was no disputing Nobunaga’s power by this point, and the resources at his disposal dwarfed anything Ieyasu could deploy. Consequently, in the aftermath of Nagashino, Ieyasu found himself a vassal to the Great Lord.

    Perhaps the best evidence of how far the relationship had shifted came in 1579, when, on Nobunaga’s order, Ieyasu had his wife and eldest son put to death on suspicion of conspiring with the Takeda to arrange Nobunaga’s assassination.

    Ieyasu’s first wife, Lady Tsukiyama.

    The long-held theory was that Lady Tsukiyama, Ieyasu’s wife, and his eldest son, Nobuyasu, were indeed conspiring with the Takeda. Some sources portray Lady Tsukiyama as a scheming, evil woman who seduced men into joining her plot, whilst Nobuyasu is said to have been a cruel, vindictive psychopath who committed acts such as shooting random peasants dead during festivals for no reason other than that they danced poorly.

    The catalyst for their death was apparently Nobunaga’s daughter, Tokuhime, who just so happened to be married to Nobuyasu. It is said that she hated her mother-in-law so much that she concocted the entire plot to have both of them removed.

    Ieyasu’s eldest son, Nobuyasu, who was either a traitor, a violent lunatic, the victim of a vindictive wife, or a combination of all three, depending on who you believe.

    There is another school of thought that suggests Nobunaga had nothing to do with the incident and that Ieyasu and Nobuyasu were instead engaged in a long-term feud. Nobuyasu, apparently supported by his mother, is said to have defied his father’s orders and even been plotting open rebellion, with or without the support of the Takeda.

    Faced with such a direct threat to his authority, Ieyasu sought the advice of his overlord, Nobunaga (who also happened to be Nobuyasu’s father in law), who is said to have instructed that, as the matter was an internal family affair, that Ieyasu should do as he thought best, resulting in the execution of Lady Tsukiyama, and Nobuyasu’s seppuku.

    Whether Nobunaga gave the order or Ieyasu acted on his own initiative, this incident highlights the situation Ieyasu faced in the late 1570s. Subordinate to Nobunaga’s power, and insecure at home, despite his successes, there was still no reason to believe that Ieyasu was going to be anything other than a footnote in another man’s story.

    Ooooh, foreshadowing!

  • The Third Unifier – Tokugawa Ieyasu. Part Two.

    The Third Unifier – Tokugawa Ieyasu. Part Two.

    The Battle of Okehazama in 1560 saw Tokugawa Ieyasu’s masters, the Imagawa, dealt a serious blow at the hands of Oda Nobunaga. In the aftermath, Ieyasu began asserting his independence, and in 1562, the so-called “Kiyosu Alliance” between Ieyasu and Nobunaga was formalised.

    The Imagawa, however, were down, but not out, and Ieyasu’s position was far from secure, despite his new alliance. In 1563, the “Mikawa Ikko-Ikki” Rebellion broke out, and in early 1564, when the Imagawa announced their intention to crush Ieyasu, several of his vassals in Mikawa switched sides, joining the Ikko-Ikki or else rising against Ieyasu in anticipation of an Imagawa attack.

    The name “Ikko-Ikki” suggests that the uprising was similar to other religiously motivated risings that occurred throughout Japan during this period. Indeed, the focal point seems to have been several temples in Mikawa; however, some scholars now suggest that the uprising was motivated more by economic reasons, and some even go so far as to say that Ieyasu may have provoked the rising, or at least took advantage of it to cement his control of Mikawa Province.

    A later depiction of the Battle of Azukizaka. Ieyasu is the figure on the white horse on the right.

    While it’s impossible to know for sure, Ieyasu did much to boost his own reputation in putting down the rebellion. At the Battle of Azukizaka (sometimes called the Battle of Batogahara) in January 1564, Ieyasu led his forces in crushing the rebels, despite ferocious fighting. The story goes that Ieyasu charged the enemy fearlessly, and came under heavy gunfire, with several rounds penetrating his armour, but leaving him uninjured, inspiring his men, and leading some rebels to switch sides.

    In the aftermath, Ieyasu banned the Jodo Shinshu sect of Buddhism in Mikawa, only to lift the ban in 1567, just a few years later, lending credence to the argument that the fighting had never been about religious issues but about political control of the province.

    The Honshuji Temple, one of the focal points of the rebellion, as it appears today.

    Before 1566, Ieyasu’s family name was Matsudaira, but around this time, he petitioned the Emperor to change it to Tokugawa. The exact reasons for this are related to the complex (and often impenetrable) genealogies of the Minamoto and Fujiwara Clans, from whom Ieyasu claimed descent. You may remember that Minamoto and Fujiwara were the names of two of Japan’s most ancient and illustrious families, and it was a big deal to claim descent from them.

    This would become much more important later, as only a member of the Minamoto could become Shogun (technically), but that was still decades in the future. At the time, the name change was probably more closely associated with prestige and a desire to assert independence from the Imagawa, with a new name symbolising a new era for the clan.

    Takeda Shingen.

    In 1567, Ieyasu further strengthened his alliance with Nobunaga by marrying his eldest son to Nobunaga’s daughter. However, they were both just nine years old at the time, so the marriage was a political rather than conjugal union. The next year, Ieyasu dispatched forces to support Nobunaga’s march on Kyoto, and in December, he made an alliance with Takeda Shingen and launched a joint invasion of Imagawa territory.

    The attack was a success, but the relationship between Ieyasu and Shingen fell apart almost immediately. According to Tokugawa accounts, it had been agreed that Ieyasu would take Totomi Province, and Shingen would take Suruga. However, it wasn’t long before Takeda forces were also crossing into Totomi, in direct violation of the agreement (which may never have existed to begin with).

    Ieyasu then sought the support of the Hojo Clan, and their Lord, Ujiyasu, who had his own ambitions for the former Imagawa territory. Together, they successfully pushed the Takeda forces back, and in 1570, Ieyasu moved his base from Okazaki Castle in Mikawa Province to Hikuma, which he promptly renamed Hamamatsu, in Totomi. Later that year, he would further prove his value as an ally of Oda Nobunaga by supporting his campaign against the Azai-Asakura Alliance, fighting in the rearguard in the defeat at Kanegasaki, and then providing important reinforcements at the victorious Battle of Anegawa in July.

    In 1571, the alliance would be sorely tested, as the last Ashikaga Shogun, Yoshiaki, sought to rally forces in opposition to Oda Nobunaga, with the ultimate goal of restoring his family’s position. The Anti-Nobunaga coalition (which was, importantly, not necessarily pro-Ashikaga) included the forces of the Azai-Asakura Alliance, the powerful temple of Ishiyama Honganji, and Takeda Shingen, among others.

    Ashikaga Yoshiaki

    In the aftermath of the defeat of the Imagawa, Hojo Ujiyasu, who had favoured an alliance with Ieyasu against the Takeda, died and was replaced by his son, Ujimasa, who reversed his clan’s diplomatic position and reestablished the alliance with Shingen. At this point, Yoshikai, seeking to take advantage of the pressure he was now under, sought to gain Ieyasu’s support, offering him the position of Kanrei or deputy Shogun in exchange.

    Ieyasu refused this offer and chose to retain his alliance with Nobunaga; in response, Takeda Shingen launched an invasion of the Mikawa and Totomi Provinces in September 1572. Leading 20,000 troops, Shingen crossed the Aokuzure Pass, and with the help of several defections amongst Ieyasu’s retainers, swiftly gained control of northern Totomi.

    A later depiction of the Takeda Army advancing into Totomi Province.

    Meanwhile, a separate force invaded Nobunaga’s territory in Mino, meaning that when Ieyasu called for aid, none was readily available. Ieyasu was forced into an impossible situation; his forces were heavily outnumbered by the advancing Takeda, and a pitched battle would almost certainly end in defeat. On the other hand, if he retreated or even stayed on the defensive, he faced the prospect of losing support from his retainers, some of whom had already proved they were willing to switch sides.

    The Takeda headed towards the strategically important Futamata Castle, and Ieyasu had no choice but to try to head them off. The advance guards of both armies clashed at the Battle of Hitokotozaka, and the Tokugawa were soundly beaten, causing them to retreat to the relative safety of Hamamatsu, and giving the Takeda a clear path to lay siege to Futamata, which fell shortly afterwards.

    In the aftermath of this disaster, still more Tokugawa retainers switched sides and joined the Takeda, and it was assumed that Shingen, whose army, strengthened by defections and reinforcements, now stood at around 30,000 men, would march on Hamamatsu. Instead, the Takeda forces bypassed it entirely. It has been suggested that this was a ploy to lure Ieyasu out of the powerful fortress, giving Shingen the opportunity to destroy him in the open.

    If that was the plan, it worked, and despite urging from his retainers to remain in Hamamatsu, Ieyasu was emboldened by some long-awaited reinforcements from Nobunaga and decided to march out and intercept the Takeda. The result was the disastrous Battle of Mikatagahara, in which the Tokugawa were decisively defeated, with Ieyasu himself only being saved by the bravery of his retainers, who fought a rearguard action so ferocious that Ieyasu was allowed to escape, and the Takeda were convinced to call off the pursuit.

    The winter of 1572 saw the Takeda forces camping deep inside Tokugawa territory, whilst Ieyasu himself was holed up in Hamamatsu, his army scattered, and his prospects looking very bleak.

    A painting of Ieyasu supposedly made after the defeat at Mikatagahara. Traditional history suggests that Ieyasu commissioned the painting as a reminder of the defeat and a warning against future arrogance; however, this account doesn’t appear in any sources before the 20th century and is now generally believed to be apocryphal.

  • 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 1

    Lords of the East, Part 1

    This post is coming out on Christmas Day, so Merry Christmas (if that’s your thing).

    We’ve taken a look at the Hojo before, their origins, and their founder, Hojo Soun, featured in a post I wrote a while back, which can be found here:

    The mon of the Hojo Clan.

    In brief, the Hojo, as they became known, were originally called the Ise, and their founder, Soun, invaded Izu Province in 1493 before conquering Odawara in neighbouring Sagami Province in 1495. It was Soun’s son, Ujitsuna, who adopted the name and mon of the Hojo Clan, who had been the de facto rulers of Japan during the late Kamakura Shogunate.

    Exactly why he chose to change the clan’s identity is a matter of some debate, with the most obvious reason being the prestige the name brought, which would help to convince the clans that were ‘native’ to the area that the Ise (now the Hojo), who had originated elsewhere, belonged.

    The Hojo based themselves permanently at Odawara from around 1516, and it is from there that Ujitsuna, the second lord (or first, if you’re feeling pedantic about names), would rule. After Soun passed the rule to him in 1518, Ujitsuna set about quite literally making his mark on Sagami Province. He was something of a prolific builder and established or rebuilt several famous shrines that still stand today.

    After 1521, Ujitsuna also began to call himself the shugo (governor) of Sagami Province. Officially, he was never bestowed with this title by the Shogun, but by this point, it hardly mattered; no one in Kyoto was in a position to stop him, and Ujitsuna ruled as governor, in fact if not technically by law.

    It’s also around this time that the Ise Clan became the Hojo Clan. Traditionally, this was seen as just an arbitrary name change, seeking to attach the somewhat lowborn Ise to an illustrious name. More recent evidence suggests that it might not have been so cynical a move, with some sources suggesting that Ujitsuna’s wife, Yojuin, was a descendant of the Yokoi Clan, who were in turn descendants of the original Hojo.

    This would still be a pretty tenuous link on its own. Still, shortly after the name change, the Imperial Court rewarded the Hojo with the title of “Saikyo no Daibu“, the same title the original Hojo were bestowed with. We’ve discussed previously how, by this point, Imperial titles were worthless on their own but still carried considerable prestige. This title put the Hojo on the same rank (in the eyes of the court, anyway) as the nearby Imagawa, Takeda, and Uesugi Clans, families with undisputed lineage.

    All this suggests that the claim to the Hojo name might not have been all that spurious, but acceptance by the Imperial Court did not translate to being a member of the ‘club’, and certainly, in the case of the Uesugi (the Ogigayatsu Branch, at least), the Hojo were little more than upstarts.

    The Sengoku Period was a time when lineage no longer held the same meaning it once did. A clan with an impressive family tree could (and often did) find itself crushed by clans that, by comparison, had no real ancestry and might have once been subordinates. This phenomenon, called Gekokujo in Japanese (which means low overthrows high), was common across the realm in this period, and a clan like the newly dubbed Hojo would set about establishing its rule at the point of a sword.

    Ujitsuna was very much a man of his time, and by the mid 1520s, he had subdued all of Sagami Province (modern Kanagawa) and advanced into southern Musashi, the neighbouring province, close to the area of modern Tokyo. Faced with further advances by the Hojo and defection of lords in Western Musashi, the Ogigayatsu were forced to respond.

    In February 1524, a Hojo force of some 10,000 clashed with the Ogigayatsu at the Battle of Takanawahara. The battle was a decisive victory for the Hojo, with the Ogigayatsu forces retreating to Edo Castle (on the site of the modern Imperial Palace), only for it to fall shortly afterwards, forcing the Ogigayatsu to withdraw further north to another stronghold at Kawagoe.

    Ujitsuna, flush with victory, ordered a rapid advance and made rapid progress before a counterattack led by Ogigayatsu ally, Takeda Shingen (remember him?), defeated the Hojo at Iwatsuki in mid 1524, obliging Ujitsuna to seek peace. He would break the peace in early 1525, and despite some early success, the Ogigayatsu, allied with the Takeda, and united with their cousins on the Yamauchi Uesugi, proved to be too much for the Hojo. In September 1525, the Hojo were defeated at the Battle of Shirakobara. Although Edo Castle would hold out, by mid-1526 the Hojo had been driven out of Musashi Province altogether, with Tamanawa Castle on the border of Sagami Province coming under attack in November that year.

    The Hojo had their back to the wall, but the forces arrayed against them were a mishmash of different clans, with different goals. A lack of coordination meant that when the time came to attack Sagami in force, the attack was beaten back, with troops of the Satomi (allies of the Ogigayatsu) making it as far as Kamakura before being defeated. During their retreat, they burned the famous Tsurugaoka Hachimangu Shrine. This carried significant political consequences, and Ujitsuna was able to convince the Imperial Court and the Shogunate to censure his enemies.

    This official reprimand created enormous political pressure, and by the end of 1527, Ujitsuna had been able to make peace. Though it is difficult to predict what the outcome might have been otherwise, it is important to remember that Hojo territory faced enemies in three directions, and it is not improbable that, had peace not been agreed, then they may have been overwhelmed.

    This reprieve was not wasted by Ujitsuna, either. In 1530, when Takeda forces once again marched against Sagami, the Hojo dispatched a force to meet them. Though the Hojo would prove victorious in this campaign, the Ogigayatsu sought to take advantage of Ujitsuna’s distraction and sent an army of their own, hoping to trap the Hojo army between them and the Takeda.

    Standing in their way was Ozawa Castle, controlled by Ujitsuna’s son and heir, Ujiyasu. Sources say that the Hojo were outnumbered as much as 5 to 1, but on the night of July 6th, 1530, Ujiyasu launched a surprise attack on their camp, winning a decisive victory and returning momentum in the war to the Hojo.

    With this momentum, the Hojo were able to take advantage of the same division that had plagued their enemies a few years earlier. Ujitsuna identified the Satomi Clan (from modern Chiba) as a weak link and focused his attention on them, bribing several family members who were unhappy with the current leadership and seeking to incite a rebellion that the Hojo could exploit.

    The plot was discovered, however, and so the Hojo instead relied on good, old-fashioned, brute force, dispatching an army across what is now Tokyo Bay to Awa Province on the southern tip of the Boso Peninsula. Despite the plot’s failure and the execution of several conspirators, some members of the Satomi still rose up in support of the Hojo invasion. What followed was a series of victories as the Hojo-Satomi alliance took castle after castle, culminating in the Battle of Inukake in 1534, which saw the Hojo-Satomi defeat their rivals and replace the head of the Satomi Clan with a Hojo ally.

    Whilst the Hojo were victorious on their eastern flank, the western flank was secured by a long-term alliance with the Imagawa. You may remember that Hojo Soun had actually started out as a vassal of the Imagawa, and though the Hojo had since risen to a position of equality with their former masters, the relationship remained close.

    With the bulk of his forces busy against the Satomi, Ujitsuna requested his Imagawa ally, Ujiteru, invade Takeda territory to ensure they wouldn’t intervene. The Imagawa obliged and invaded Kai Province in July 1534; they were initially successful but soon became overextended and had to retreat to their home in Suruga. A Takeda counterattack was considered so dangerous that Ujitsuna withdrew forces from the West to face it. The Takeda, remembering their defeat at the hands of the Hojo a few years earlier, tried to lure Ujitsuna into an ambush in the narrow mountain passes of Kai, seeking revenge.

    Ujitsuna was apparently aware of the strategy, however, and dispatched a force to outflank the Takeda, turning the ambushers into the ambushed at the Battle of Yamanaka on September 19th, 1535. The defeat was so severe for the Takeda that the road into Kai province now lay open, and Ujitsuna apparently intended to crush the Takeda once and for all and take the whole of Kai Province for himself.

    This invasion was eventually called off as the Ogigayatsu proved to be a more pressing concern, and over the next few years, the geopolitical situation would shift considerably. In 1536, Imagawa Ujiteru died suddenly, aged just 21 or 22. He left no heirs, and so the clan quickly descended into civil war. At about the same time, famine and an epidemic broke out in Kai Province, severely weakening the Takeda.

    The Imagawa civil war was won by Yoshitomo, Ujiteru’s younger brother, but the devastation in Suruga left the clan severely weakened, and they sought peace with the Takeda, who, suffering their own calamities, quickly agreed, with Yoshitomo marrying Takeda Shingen’s daughter to establish a new alliance. Ujitsuna recognised that his alliance presented an intolerable risk to his western frontier and resolved to do something about it.

    In early 1537, Ujitsuna led 10,000 men into Suruga Province, winning a series of crushing victories over the Imagawa and decisively bringing an end to decades of close relations. Fearing overextension, however, Ujitsuna limited his conquests to the territory east of the Fuji River, and a truce was declared shortly afterwards, which was convenient, as the death of the Ogigayatsu lord left the clan in disarray and presented a golden opportunity for further Hojo expansion, but we’ll talk about that next time.
