Kajiki

The Kajiki were a warrior house of Ōsumi Province in southern Kyushu, named for the Kajiki valley. Their founder was Fujiwara no Tsunehira, third son of the regent Fujiwara no Yoritada, who in the late tenth century married the daughter of the local magnate Ōkura Yoshinaga, settled on his wife's lands and took the place name as his family name. As Kamakura gokenin the clan reached its height helping to repel the Mongol invasions of Japan.

During the Nanboku-chō wars it split into factions backing Ashikaga Takauji and Ashikaga Tadayoshi, and under the Muromachi shogunate it served the Shimazu, shugo lords of Ōsumi.

The family later adopted Mitsuhisa, a son of Shimazu Suehisa, but Mitsuhisa's son Hisahira rebelled and in 1495 raided Chōsa; Shimazu Tadamasa stormed Kajiki Castle the next year, and the Kajiki were removed to Ata in Satsuma.
