Yamana Tokiuji

Yamana Tokiuji (c. 1303–1371) was a Nanboku-cho shugo lord of the Yamana clan. He joined Ashikaga Takauji's break with Emperor Go-Daigo and fought at the Minatogawa in 1336, becoming shugo of Hoki in 1337 and winning further provinces after the 1341 campaign against Enya Takasada.

During the Kanno disturbance he changed sides repeatedly, even occupying Kyoto with Southern Court armies in 1353 and 1354. He submitted to the Muromachi bakufu in 1363 with his sons, receiving Hoki and Tamba. By his death in 1371 the Yamana held five provinces.
