  • The Shimazu, Part 1

    The Shimazu, Part 1

    Last time we looked at Shikoku, the so-called ‘four provinces’, well, how about an island of nine provinces? That’s right, Kyushu, the third largest of Japan’s main islands, is so called because in the pre-modern period it was home to nine whole provinces, which means, as names go, it’s not terribly creative, but what can you do?

    In ancient times, Kyushu had been the centre of cultural, economic, and social development in Japan, as its close proximity to Korea, and by extension China, made it the logical landing site for innovations as widespread as rice farming and written language. The island would also be the focus of two ultimately unsuccessful Mongol invasions in the 13th Century, and the Shogunate administration there would continue to be important until the decline of central authority in the 15th Century left Kyushu, much like the rest of the realm, effectively independent.

    Into this power vacuum stepped several powerful clans, with the most prominent arguably being the Ouchi, Otomo, and Shimazu. Though the Ouchi and Otomo would play important roles of their own in the story of the Sengoku Period, it is the Shimazu that we will be focusing on.

    The exact origins of the Shimazu name aren’t entirely clear, but the first figure to take the name was Tadahisa, who was made lord of the Shimazu Manor in southern Kyushu in 1185. Tadahisa himself is something of a mysterious figure, with various conflicting reports of his origins, parentage, and even his name, but what is clear is that the Shimazu were well established in southern Kyushu by the 13th century, and would use it as their base going forward.

    Shimazu Tadahisa, the first “Lord” Shimazu.

    Tadahisa’s son, Tadatoki, seems to have been an accomplished military leader, as he was appointed the shugo (military governor) of Satsuma, Osumi, and Hyuga Provinces, all of southern Kyushu in effect. He was also granted numerous prestigious lands and titles around the realm, but it was his Kyushu holdings that would be the most important for his descendants.

    The Shimazu’s fortunes would ebb and flow over time, but the distance of their lands from the centre of power in Kyoto meant that they were often able to weather the storms of early Medieval Japan. They were not immune from the ever-present problem of internal conflict, however, and by the time of the Onin War in 1467, the Shimazu were weak, divided, and vulnerable.

    It would be Shimazu Tadayoshi (1492-1568) who would begin to turn the fortunes of the clan around. Originally from the Isaku Clan (a branch of the Shimazu), Tadayoshi had a difficult start to life. His father, Yoshihisa, was apparently murdered by a stable hand when Tadayoshi was just two, and his grandfather was killed in battle in 1500. Following this, Tadayoshi’s mother, Lady Baiso, agreed to marry the lord of another branch of the Shimazu, on the condition that Tadayoshi be adopted as heir to both branches. The lord in question was apparently so keen on Lady Baiso that he agreed.

    Shimazu Tadayoshi.

    Tadayoshi proved to be an enlightened and capable ruler, taking inspiration from Zen teachings and humanitarian principles. He was a popular leader, as he genuinely cared for the needs of his retainers and the welfare of his territory, but his son, Takahisa, would prove to be greater still. In 1526, following the deaths in quick succession of both his sons, the head of the main branch of the Shimazu Clan, Katsuhisa, turned to Tadayoshi (renowned for his learning and upright conduct) for a solution to the succession issue.

    Tadayoshi had Takahisa adopted by the Lord of the Shimazu. In November 1526, Katsuhisa handed over control of the Shimazu Clan to Takahisa and retired to a monastery. Tadayoshi became a monk himself shortly afterwards and would go on to play a significant role in aiding his son in reestablishing Shimazu power in southern Kyushu.

    Shimazu Takahisa.

    Things are never quite that simple, however, and Takahisa’s accession to the leadership of the Shimazu was opposed by several powerful retainers, some of whom also claimed the right to lead. Katsuhisa himself also seems to have expressed some regret about handing over power, and in June 1527, an army was raised which drove Takahisa out, and had Katsuhisa returned as the shugo.

    The fighting would go back and forth for a while after this, despite unsuccessful efforts to arrange a reconciliation in 1529. Katsuhisa proved to be an unpopular lord, however, apparently being more focused on ‘vulgar entertainment’ than the business of ruling. Though this did not automatically translate into support for Takahisa, the division amongst his enemies handed him the initiative.

    Starting in 1533, Takahisa would lead a series of counter-attacks which eventually saw him establish control over most of Satsuma Province, and in 1539, the decisive Battle of Murasakihara saw Takahisa drive out his primary rivals, though it wouldn’t be until 1552 that he was finally recognised as the shugo of Satsuma Province by the Shogunate, 26 years after he had first assumed the mantle.

    Takahisa had long hoped to reestablish Shimazu control of the three provinces held by his ancestors, and he would lead campaigns into neighbouring Osumi province from 1554 to 1556, which would allow him to establish a foothold in the province from which further expansion could be launched.

    Though Takahisa would prove to be a successful warrior, he was also known for his outward-looking attitude towards foreigners. The Shimazu had long had trade with Ming China, largely through intermediaries in the Ryukyu Islands (modern Okinawa), and after Portuguese merchants arrived in Japan, Takahisa was one of the first lords to welcome them to his domains, and perhaps one of the first to employ firearms in battle.

    He would also go some way to establishing Christianity in Japan, as he welcomed Francis Xavier into his territory in 1549, though this would ultimately prove a short-lived association, due to backlash from conservative elements amongst the Buddhist and Shinto priesthoods.

    Takahisa would eventually retire to a monastery in 1556, handing control of the Shimazu over to his son, Yoshihisa, who also inherited his father’s ambitions to regain control of the three provinces of Satsuma, Osumi, and Hyuga. Yoshihisa had actually joined his father’s campaign in Osumi, making his ‘debut’ in 1554, and after inheriting the leadership from his father, he would continue the campaigns to fully pacify Satsuma and expand Shimazu holdings into the neighbouring provinces.

    Satsuma would come under his complete control in 1570. In 1572, a rival clan from Hyuga Province would invade Shimazu territory, only to be defeated in short order at the Battle of Kizakihara, with the Shimazu forces being led by Yoshihisa’s highly capable younger brother, Yoshihiro. It is said that the Shimazu, despite being outnumbered 10 to 1, launched an aggressive attack against the enemy, which saw several key leaders killed and over 500 enemy deaths (counted in heads taken after the battle).

    A later depiction of a head viewing (kubi-jikken), a common practice among Samurai, in which the heads of defeated enemies would be presented to lords, or otherwise publicly displayed.

    This victory allowed Yoshihisa to focus on Osumi Province, which he was able to fully conquer by the end of 1573. Then in 1576, he captured the strategically important Takahara Castle, held by the powerful Ito Clan of Hyuga. The fall of Takahara led to a domino effect in which the remaining 48 castles of the Ito Clan were either conquered or defected to the Shimazu. Not long after, the head of the Ito Clan, Yoshisuke, fled Hyuga, and the long-dreamt-of reunification of the three provinces was achieved.

    Almost as soon as the dust had settled, however, the powerful Otomo Clan, who controlled several provinces in North-Eastern Kyushu, invaded, nominally in support of the exiled Yoshisuke, but more likely in an opportunistic attempt to expand their own territory. A huge army of some 43,000 men crossed into Hyuga Province in October 1578 and laid siege to Takashiro Castle. The Shimazu under Yoshihisa could muster only 20,000 men in response, but they took advantage of poor coordination amongst the Otomo, dealing with the invaders piecemeal.

    The campaign culminated in the Battle of Mimikawa (which was actually fought nearly 20 miles from the eponymous river), in which Yoshihisa employed a series of feigned retreats, breaking the Otomo Army (which still enjoyed a numerical advantage) down, and eventually winning a victory that was so comprehensive the Otomo effectively ceased to be serious rivals.

    The war wouldn’t end at Mimikawa, however, and in 1580, Oda Nobunaga began negotiations between the Otomo and Shimazu, hoping to bring an end to the war, since he wanted the Otomo to join his upcoming campaign against the Mori. The negotiations were apparently successful, as Yoshihisa even went so far as to recognise Nobunaga as his ‘lord’, and planned to join the attack on the Mori as well.

    As we already know, Nobunaga’s death at the Honnoji incident in June 1582 put an end to those plans, but the weakened state of the Otomo and the fact that the peace deal no longer applied meant that the Shimazu were able to defeat or force the defection of several former Otomo retainers, increasing their own power and control over southern Kyushu.

    The campaign to unify the entire island would go on, but we’ll look at that next time.

  • (No longer) Lords of the Four Provinces

    (No longer) Lords of the Four Provinces

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

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

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

    Toyotomi Hideyoshi, who would eventually become master of Japan.

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

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

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

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

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

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

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

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

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

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

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

    An early 20th century depiction of Chosokabe Morichika.

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

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

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

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

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

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

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

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

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