Shibata clan (Echigo)
The Shibata of Echigo province were descended from Sasaki Moritsuna, a supporter of Minamoto Yoritomo and a son of Sasaki Hideyoshi (1112-1184). They later became retainers of the Nagao and served Uesugi Kenshin. They attempted to break away from the Uesugi after 1578 and when Shibata Shigeie died in 1587, the Shibata became extinct. The Shibata of Echigo were related to the Shibata of Owari province, with whom they shared a common mon or a variation on it.
