Hatakeyama Kuniuji

Hatakeyama Kuniuji was a Nanboku-chō warrior and the heir of Hatakeyama Takakuni. Appointed Ōshū kanrei in 1345, he joined his father at Taga in Mutsu to subdue Southern Court forces.

He later clashed with Kira Sadaie, an ally of Ashikaga Tadayoshi, siding with Takauji in the Kannō Disturbance. In 1351 Sadaie's troops besieged Iwakiri Castle, and Kuniuji and his father took their own lives. His son Kuniakira became ancestor of the Nihonmatsu clan.
