Hishikari Shigetae
Fujiwara no Shigetae, later known as Hishikari Shigetae, was by tradition a grandson of Fujiwara no Takanaga, exiled to Izu after the Hōgen War of 1156.
Minamoto no Yoritomo confirmed his estates in Ōsumi, where he settled and became ancestor of the Hishikari clan. Tradition also credits him with founding the Kōriyama Hachiman shrine in 1194, inviting its deity from Usa Hachiman.
