Shimazu Sadahisa

Shimazu Sadahisa (1269–1363) was fifth head of the Shimazu and shugo of Satsuma, Ōsumi and Hyūga. He succeeded his father Tadamune as shugo of Satsuma in 1318, and in 1333, answering Ashikaga Takauji's call against the Kamakura shogunate, he helped destroy the Chinzei deputy Hōjō Hidetoki, gaining Ōsumi and Hyūga as reward.

He aided Takauji at Tatara beach in 1336 and then spent decades fighting Southern Court forces in Kyūshū, at one point submitting to them during the Kannō disturbance. In 1363 he divided Satsuma and Ōsumi between his sons Morohisa and Ujihisa and died aged ninety-five.
