Vassal of the Uesugi Clan who mainly served as a magistrate under Uesugi Kenshin in Kyoto. He acted as negotiator for the Uesugi Clan in the Imperial Court and Shogunate in such matters as trade in commodities particular to Echigo.

He became master of Sanjou Castle after the death of Yamayoshi Toyomori. In the Otate no Ran, he apparently joined Uesugi Kagekatsu's side at first along with Yamayoshi Kagenaga, but later fought on Uesugi Kagetora's side with Honjou Hidetsuna. After Kagetora's death, he continued to oppose Kagekatsu, but in the end was betrayed and killed by one of his vassals within Sanjou Castle who was in collusion with Yamayoshi Kagenaga.
