Yamana

The Yamana were a warrior family originating in Kōzuke Province. Yamana Tokiuji became governor of Hōki in 1337, and his descendants eventually held governorships in eleven provinces. The family lost much of its power after the Meitoku rebellion against the shogunate in 1391.

Yamana Sōzen led the western army against Hosokawa Katsumoto in the Ōnin War, which began in 1467. In 1580 Yamana Suketoyo surrendered in Tajima to Hashiba Hideyoshi's forces; another branch survived at Muraoka under the Tokugawa.
