Kira Osauji

Kira Osauji (1211–1290) was a mid-Kamakura warrior and gokenin, the eldest son of Ashikaga Yoshiuji and founder of the Kira clan. Born to a low-ranking mother, he could not inherit the main line and took Kira Manor in Mikawa as his fief and name.

First named in 1228 escorting Shōgun Fujiwara no Yoritsune, he served until 1241 and then returned to Kira Manor. In 1251 he built Tsurugasaki Tenmangū. After his heir Mitsuuji died in the Shimotsuki incident of 1285, he adopted his grandson Sadayoshi, and died in 1290 aged eighty.
