Imagawa clan domain

1476 CE – 1569 CE (approx.) · capital Sunpu

The domain of the Imagawa of Suruga, a leading Sengoku power whose ruler Yoshimoto was killed by Oda Nobunaga at Okehazama in 1560.

Origins

The Imagawa, a branch of the Ashikaga, had long been governors of Suruga. After Imagawa Yoshitada died in battle in 1476, a succession dispute was settled with help from Ise Moritoki, later known as Hojo Soun, who secured the domain for the young Ujichika.

Rule and society

Ujichika expanded into Totomi and issued one of the earliest Sengoku house codes, the Imagawa kana mokuroku of 1526. His son Yoshimoto made Sunpu a cultured capital, took control of Mikawa, held the young Tokugawa Ieyasu as a hostage and allied with the Takeda and Later Hojo, becoming the strongest lord on the Tokaido.

Decline and legacy

Marching west in 1560, Yoshimoto was killed in a surprise attack by Oda Nobunaga at Okehazama. His son Ujizane lost Sunpu to Takeda Shingen in 1568 and surrendered Kakegawa castle to Tokugawa Ieyasu in 1569, ending the domain.
