Ōtomo Ujiyasu

Ōtomo Ujiyasu (c. 1321–1362) was the seventh head of the Ōtomo clan of Bungo Province. In 1333 his father Sadamune passed him the headship before marching against the Hōjō, and Ujiyasu succeeded on his father's death that year.

When Ashikaga Takauji fled to Kyushu in 1336, Ujiyasu helped him regain power; Takauji made him a nominal son and granted the character uji, and the Muromachi bakufu named him shugo of four provinces. He died in 1362, succeeded by his brother Ujitoki.
