The Hatano claimed descent from Fujiwara Hidesato (ca.940) and were founded by a certain Hatano Tsunenori. Eight generations later, Hatano Tsunemoto settled in Tanba province. Here they remained until being destroyed by Oda Nobunaga in 1579. Another, obscure, branch of the Hatano resided in Echizen province.
