Tsunetsura Inawashiro

Tsunetsura Inawashiro was an early Kamakura-period warrior who founded the Inawashiro house of Aizu. The eldest son of Moritsura Sahara, of a warrior line claiming Kanmu Heike and Miura descent, he is said to have held Inawashiro in the Yama district after his grandfather Yoshitsura Sahara was enfeoffed with the four Aizu districts for his part in the Ōshū campaign of 1189.

Local records place his fort at Yadeyama, later called Kamega-jō, in 1191; the Date family genealogy instead says that in 1248, while serving Shogun Fujiwara no Yoritsugu, he received the Asaya estate and took the name Inawashiro.
