Chūjō Ienaga
Chūjō Ienaga (1165 – 26 September 1236) was a Kamakura-period warrior of the Yokoyama league in Musashi province, the eldest son of Chūjō Kanetsuna. Adopted by Hatta Tomoie, he took the surname Chūjō and claimed descent from the Michikane line of the northern Fujiwara.
He fought under Minamoto no Noriyori at Ichinotani in 1184 and in the Ōshū campaign of 1189–1190. In 1225 he joined the first Council of State, helping frame the Goseibai Shikimoku.
