Fujiwara no Tsunehira

Fujiwara no Tsunehira was, by Kajiki family tradition, the third son of the Fujiwara kampaku Fujiwara no Yoritada (924–989). In the mid-Heian period Ōkura no Yoshinaga, head of the local Ōkura clan of Kajiki in Ōsumi Province, had no male heir and adopted Tsunehira as a son-in-law.

Tsunehira settled on the estate and took the place name as his family name, becoming ancestor of the Kajiki warrior house, whose descendants served the Kamakura shogunate as gokenin and helped repel the Mongol invasions.
