Toyotomi Hideyori (August 28, 1593 – June 4, 1615) was the son and designated successor of Toyotomi Hideyoshi, the general who first unified Japan. His mother, Yodo-dono, was Oda Nobunaga's niece.
Early Life and Political Struggles
Born in 1593, Hideyori was Hideyoshi's second son. His birth created a potential succession crisis, leading Hideyoshi to exile and later order the forced suicide of his nephew and heir, Toyotomi Hidetsugu, in 1595. Hidetsugu’s entire family, including women and children, were executed, solidifying Hideyori’s position as Hideyoshi’s successor.
Following Hideyoshi’s death in 1598, Japan was ruled by a council of five regents intended to govern until Hideyori came of age. However, Tokugawa Ieyasu quickly maneuvered to seize power, culminating in his victory at the Battle of Sekigahara in 1600. To neutralize Toyotomi influence, Ieyasu arranged Hideyori’s marriage to his granddaughter, Senhime, hoping to solidify political ties.
Conflict with Tokugawa
By 1614, Hideyori, now a young daimyō ruling from Osaka Castle, was seen as a growing threat by Ieyasu. Many samurai opposed to Tokugawa rule gathered around Hideyori, claiming he was Japan’s rightful leader. Tensions escalated when Hideyori held a dedication ceremony for the Great Buddha of Kyoto, which Tokugawa authorities interpreted as a prayer for their downfall. Ieyasu demanded Hideyori vacate Osaka Castle, but his supporters refused, prompting the Siege of Osaka (1614–1615).
The Siege of Osaka
The first phase, the Winter Campaign (1614), saw Tokugawa forces fail to breach the castle. A truce was reached, but the Tokugawa shogunate forced Hideyori to dismantle Osaka Castle’s defenses. In April 1615, Ieyasu learned Hideyori was amassing troops and preparing for war. The truce was broken, leading to the Summer Campaign (1615).
In the final battle on June 4–5, 1615, Hideyori’s forces initially performed well, using surprise tactics under Sanada Yukimura. The Tokugawa forces suffered heavy losses, and Ieyasu himself allegedly considered suicide when defeat seemed imminent. However, due to a miscommunication—caused by a letter from Ieyasu warning of a supposed conspiracy inside the castle—Hideyori delayed his attack, allowing the Tokugawa to regroup. Overwhelmed by superior numbers, Osaka Castle fell.
As Tokugawa troops stormed the castle, Hideyori and his mother, Yodo-dono, took refuge in a fireproof keep. Senhime attempted to negotiate for her husband's life, but Ieyasu refused, ordering his commanders to finish the attack. Under relentless artillery fire, Hideyori and his mother committed seppuku, marking the end of the Toyotomi lineage as a political force.
Aftermath and Legacy
Toyotomi Kunimatsu (Hideyori’s 8-year-old son) was captured and executed.
Naahime (Hideyori’s 7-year-old daughter) was sent to Tōkei-ji, a convent in Kamakura, where she later became its 20th abbess, Tenshūin (1608–1645).
Rumors persisted that Hideyori had escaped Osaka, causing concern for the Tokugawa shogunate. Reports from foreign sources, such as Richard Cocks and Jesuit missionaries, document that some believed Hideyori had fled to Satsuma or even overseas.
With Hideyori’s death, the last major resistance to Tokugawa rule ended, securing Tokugawa dominance for over 250 years.
