Hei no Yorimoto

Hei no Yorimoto was a warrior of the late Heian and early Kamakura periods, remembered as founder of the Hei clan of Hei district in Mutsu. Late Edo genealogies claim he was the third son of Minamoto no Tametomo, who escaped exile in Izu and reached the Sanriku coast.

Said to have met Yoritomo in the 1189 Oshu campaign, he took the name Sasaki Juro Yukimitsu, received Hei and Kesen districts after the Northern Fujiwara fell, and then called himself Hei no Yorimoto. No contemporary source supports his claimed Genji birth.
