Toyotomi Hideyoshi

Toyotomi Hideyoshi (1537–1598) was the supreme ruler of Japan who completed the unification of the country following the Sengoku period and launched the Imjin War against Joseon Korea.

Rise from Humble Origins

Born into poverty as the son of a peasant foot soldier in Owari Province, Hideyoshi joined the service of Oda Nobunaga as a sandal-bearer. Demonstrating extraordinary intelligence, diplomacy, and military logistics, he steadily rose through the ranks to become one of Nobunaga's top generals.

Unification of Japan

When Nobunaga was assassinated in the Honno-ji Incident in 1582, Hideyoshi acted swiftly to defeat the traitor Akechi Mitsuhide at the Battle of Yamazaki. He outmaneuvered rival generals, completed cadastral land surveys (Kenchi), and enacted the Sword Hunt (Katanagari) to disarm peasants and enforce strict social hierarchy. By defeating the Hojo clan at Odawara in 1590, Hideyoshi achieved the complete unification of Japan, assuming the title of Taiko (Retired Regent).

The Imjin War and Death

To channel the restless military energy of Japan's samurai warlords outwards and fulfill his grandiose ambition of conquering Ming China, Hideyoshi launched a full-scale invasion of Joseon in 1592. Despite initial rapid land advances, the invasions met fierce resistance from Joseon's navy under Admiral Yi Sun-sin, civilian Righteous Armies, and Ming expeditionary forces. As the war dragged on into a second phase (1597), Hideyoshi fell ill and died at Fushimi Castle in September 1598, leaving behind orders for immediate withdrawal from Korea.
