A number of samurai clans, including the Chōsokabe clan of Shikoku, the Kawakatsu clan of Tanba, and the Jinbō clan of Echigo province, claimed descent from the Hata. The Koremune clan, also allegedly descended from the Emperor of Qin, were related to the Hata as well. Prince Koman-O came to dwell in Japan in the reign of Emperor Ōjin (c. 310). His successors received the name Hata. This name was changed to Koremune in 880. The wife of Shimazu Tadahisa (1179–1227) (son of Minamoto no Yoritomo and ancestor of the Shimazu clan of Kyūshū), was a daughter of Koremune Hironobu.
