A childless shogun adopted his brother as heir in 1464, then his wife bore a son, and the quarrel burned Kyoto for 11 years

Ashikaga Yoshimasa, the eighth shogun, married Hino Tomiko in 1455. Their first son was stillborn in 1459. With no son, in 1464 Yoshimasa adopted his younger brother, a Buddhist abbot, who left the priesthood and took the name Yoshimi. The next year Tomiko gave birth to a son, Yoshihisa. Tomiko wanted her son to be shogun. The two great lords Hosokawa Katsumoto and Yamana Sōzen were already rivals, and the Hatakeyama and Shiba houses were each split by their own succession quarrels. In the 5th month of 1467 Hosokawa's Eastern Army backed Yoshimi and Yamana's Western Army fought in the capital. Later the sides swapped: Yoshimi joined the Western Army and Yoshimasa stripped him of his titles. The war spread across Japan, Kyoto was burned, and the shogun's authority never recovered. Tomiko ran toll barriers on the roads into Kyoto and lent money at interest, once lending 1,000 kan to a Western general. Yoshihisa became shogun in 1473 and died on campaign in 1489. Yoshimasa died in 1490. On Tomiko's recommendation the next shogun was Yoshitane, the son of Yoshimi, the brother she had fought. He was driven out in 1493.
