Ashina Yasumori

Ashina Yasumori was a Kamakura-period warrior of the Ashina family of Aizu, an offshoot of the Miura clan's Sahara line. A son of Sahara Mitsumori, he was the younger brother of Ashina Tsunemitsu, who became shugo of Hōki in 1272.

After Tsunemitsu lost the post and wandered the provinces, Yasumori overran his private estates and called him a beggar; the Kamakura bakufu found him guilty and restored the lands to his brother. Yet the later Ashina lords of Aizu descended from Yasumori's line.
