Taiko Toyotomi Hideyoshi – Chris Perry, Author

By the late 1580s, Hideyoshi was at the very pinnacle of political and military power in Japan. Jesuit records from the time name him “tyrant” and suggest that he has achieved more power over the realm than any warlord before him.

After the successful conclusion of the Kyushu Campaign, Hideyoshi ordered a new palace built in Kyoto. Called Jurakudai (or Jurakutei in some sources), Toyotomi moved his political base there from Osaka Castle in early 1588, inviting the Emperor Go-Yozei for a feast in April 1588 and obliging powerful Daimyo (such as Tokugawa Ieyasu) to travel there and pay homage to him.

Having secured personal political power, Hideyoshi then turned his attention to pacifying the realm at large. Through his military campaigns, he had subdued most of the powerful Daimyo in the realm, but there remained the issue of establishing peace at the local level as well.

The Sengoku Jidai exists in the popular imagination as more than a century of conflict, featuring epic clashes between armies of Samurai loyal unto death, and iconic lords like Takeda Shingen, Oda Nobunaga, and Uesugi Kenshin, who were locked in a titanic struggle for ultimate control of the realm.

Uesugi Kenshin and Takeda Shingen engaged in a duel that probably never happened but remains an enduring, if inaccurate, image of the Sengoku-era battlefield.

Whilst there is certainly truth to this image, much like any period of civil war, Japanese society at large had become incredibly violent during the 16th century. At the local level, the decentralised nature of Daimyo rule led to the emergence of Jizamurai, literally “Local Samurai”. These men often started out as armed peasants, usually levied into the armies of some local lord, and sent home again when the campaign ended.

Throughout the 16th century, these Jizamurai gradually achieved military and political influence over their local communities, often being allowed to collect tax revenue on behalf of their lord in exchange for military service, similar to a Knightly Manor in medieval Europe.

This situation worked fine whilst the realm was fractured into dozens of minor domains, but as consolidation followed conquest in the latter half of the 16th century, tensions between “Samurai” and “Jizamurai” became more of an issue. When a lord was defeated, he was usually killed or deprived of his land, meaning that the Jizamurai would often find themselves serving a new lord to whom they had no personal loyalty, leading to frequent conflicts.

On a societal level, the distinction between Jizamurai and peasants was often academic. Though technically of a higher social status, a Jizamurai usually lived in the village, amongst the peasantry, who would themselves often have access to weaponry and a far greater loyalty to their local Jizamurai than to some powerful Daimyo whom they never saw.

This led to frequent Peasant Uprisings throughout the Sengoku Period, most famously the Ikko-Ikki, who were motivated by religious fervour but were largely made up of peasants and Jizamurai. It wasn’t just political violence; feuds between villages were common and often escalated into violence, as rival communities would quickly resort to the sword to settle disputes over territory, waterways, and other local matters.

In 1587, Hideyoshi passed a law forbidding the use of force to resolve such disputes. Though the exact wording of the law has been lost, by looking at the wording of laws from the later Edo Period, which often referred to ‘precedents’ (i.e., earlier laws), we can infer what Hideyoshi’s decrees may have looked like.

If any villagers or other people in a village engage in a dispute over mountains or waters, using bows, spears, or guns to fight amongst themselves, that entire village shall be punished. – From a decree by Shogun Tokugawa Hidetada -1610

Scholars debate exactly what Hideyoshi intended with this law, with some suggesting that he meant to disarm and pacify the peasants, whilst others say it was more to do with establishing who had weapons, and who had the right to weapons, part of an ongoing centralisation campaign in which a clearer line was to be drawn between Warrior and Peasant.

In 1589, Hideyoshi celebrated the birth of a son, Tsurumatsu, whom he swiftly named as his heir, securing his dynasty for the foreseeable future. The following year, after a series of political slights, he launched a decisive campaign against the Hojo, lords of the Kanto, crushing them in the Odawara Campaign.

Also in 1590, he crushed the defiant clans of Northern Japan in a swift campaign, and it is at this point that the “Sengoku Jidai” is said to have come to an end. For the first time in more than a century, the country was under the control of one man, and the realm would never again fracture as it once had. Despite this, one decision made by Hideyoshi in the aftermath of the Odawara Campaign had already sown the seeds of his clan’s ultimate downfall.

With the destruction of the Hojo, Hideyoshi offered the five provinces of the Kanto to Tokugawa Ieyasu, in exchange for the three he had originally ruled. At the time, this move was seen as political savvy. It positioned the potentially rebellious Ieyasu farther from Kyoto, and though the five Kanto provinces were nominally richer than the three Ieyasu had given up, they had recently been conquered and were potentially volatile, meaning the move weakened Ieyasu in the short term.

Hideyoshi, however, had not considered Ieyasu’s political and economic acumen. His base in the Kanto would eventually serve as a springboard for his own rise to power, demonstrated perhaps most clearly by the fact that Japan’s modern capital, Tokyo, is on the same site as Ieyasu’s was, more than 430 years after he moved there, but we’re getting ahead of ourselves.

The threat from Ieyasu was not Hideyoshi’s only concern, however. In 1591, his brother, Hidenaga, who had proven to be an extremely competent commander and political ally, died in February, followed by his son and heir, the two-year-old Tsurumatsu, in September of the same year.

Following these deep personal and political blows, Hideyoshi adopted his nephew, Hidetsugu, and then retired, handing control of the clan over to him. As was common at the time, Hideyoshi retained true political power; however, becoming known as the Taiko, a title of respect for former regents.

Also in 1591, with Japan secured, Hideyoshi announced his intention to invade China, launching a brutal invasion of Korea to use it as a base for his main objective. We’ll give the Korean Wars their own post, but for now, we can say that the invasions both highlighted Hideyoshi’s power and brought about political divisions that would ultimately destroy his legacy.
