Yūki Sadahiro

Yūki Sadahiro (1289–1309) was a late Kamakura warrior and the fifth head of the Shimōsa Yūki clan. His father Tokihiro died in 1290 when Sadahiro was not yet one year old, so he inherited as an infant and his mother administered the clan's affairs until he came of age.

During his headship the Yūki abandoned Jōdo Shinshū Buddhism and turned to Zen. He died in 1309, aged twenty-one, and his one-year-old son Tomosuke succeeded him.
