Imagawa Yoshimoto - Battle of Okehazama and Death

Battle of Okehazama and Death

In the summer of 1560, after forming a three-way alliance with the Takeda and the Hōjō, Yoshimoto headed out to the capital with Tokugawa Ieyasu (then known as Matsudaira Motoyasu) of Mikawa in the vanguard. Despite having a strong force of 25,000, Yoshimoto deliberately announced that he had 40,000 troops. While this statement put fear in many factions, Oda Nobunaga of Owari Province saw through it. (Some historical sources support the claim of 40,000.)

With many victories, Yoshimoto's army was letting its guard down, celebrating with song and sake. A surprise attack by the Oda army of 3,000 following a downpour left Yoshimoto's army in complete disorder. Two Oda samurai (Mōri Shinsuke and Hattori Koheita) ambushed the Imagawa army and killed Yoshimoto, in the village of Dengakuhazama.

Imagawa Ujizane succeeded to family headship after Yoshimoto's death, but the Imagawa clan fell from power. Ujizane was later summoned by Tokugawa Ieyasu and became a kōke in the administration of the Tokugawa clan. Yoshimoto's niece was Lady Tsukiyama, the wife of Tokugawa Ieyasu.

Yoshimoto has several graves; his body itself is buried at Daisei-ji, a temple in the city of Toyokawa in modern Aichi Prefecture.
