Shimazu Tadahisa

Shimazu Tadahisa (died 1227), born Koremune no Tadahisa, was a Kamakura shogunate vassal and founder of the Shimazu clan. In 1185, on Minamoto no Yoritomo's recommendation, he became a deputy administrator of the Shimazu estate in southern Kyushu, later taking his name from the estate.

He became shugo of Satsuma and Ōsumi in 1197. Implicated in the Hiki purge of 1203, he lost his governorships but recovered Satsuma after backing the Hōjō in the 1213 Wada conflict. He died at Kamakura in 1227.
