Ōida Ujitsune

Ōida Ujitsune was a Southern Court warrior from a Nitta branch clan settled at Ōida in Echigo's Uonuma District and the son of Ōida Tsunetaka. In 1333 he and his father joined Nitta Yoshisada's rising and fought at the Battle of Kamakura against Hōjō Takatoki. He served Yoshisada across the country, holding Fukuyama in Bitchū against Ashikaga Takauji before defeat by Tadayoshi.

He followed Yoshisada to Hokuriku and, after his lord's death, protected Nitta Yoshimune, thrice battling the Ichikawa of Shinano and campaigning through Hokuriku and Musashi.
