The Sakakibara claimed descent from the Seiwa Genji via the Nitsuki clan, who ruled two districts of Iga Province from the early Muromachi period. The 9th generation descendant of Nitsuki Yoshinaga relocated to Sakakibara village in Ise Province (part of the present-day city of Tsu, Mie) and his son, Toshinaga was the first to take the name of "Sakakibara".Papinot, Jacques.
