Hei no Chikamitsu
Hei no Chikamitsu was a warrior of the Hei clan of Mutsu province and a son of Hei no Mitsuyori. After the Kamakura shogunate fell in 1333, he took service with Kitabatake Akiie, governor of Mutsu, who confirmed the family's holdings in Hei district.
The clan then marched south in Akiie's Oshu army on the Southern Court side, routing Ashikaga Takauji's forces at Aonogahara before defeat at Ishizu, both in 1338.
