Mitsuzumi Iwamatsu

Japanese: 岩松満純 - いわまつ・みつずみ

Year of death: 24th year of Oei, 13th year of leap year 5 (June 27, 1417)
Year of birth: Year of birth unknown. Military commander of the Muromachi period. Lord of Nitta Manor in Kozuke Province (Gunma Prefecture). Son of Mitsukuni. Jibu-daifu. There is also a theory that he was the surviving child of Nitta Yoshimune and was adopted by Mitsukuni. As he was married to the daughter of Inukake Uesugi Ujinori (Zenshu), he played an active role in supporting Ujinori's coup d'état in Kamakura in 1416. It is said that he boasted about his military achievements at the time, earning the hatred of those around him. When Ujinori was defeated in an attack by the Muromachi Shogunate forces in January of the following year, he fled and started a revolt in Nitta Manor, but was captured fighting Maiki Mochihiro and was beheaded in Kamakura.

室町時代の武将。上野国(群馬県)新田荘の領主。満国の子。治部大輔。新田義宗の遺児で満国の養子になったとの説もある。犬懸上杉氏憲(禅秀)の娘を妻としていた関係で,応永23(1416)年に氏憲が鎌倉でクーデタを起こした際にはこれに加担して活躍。このとき,自らの戦功を誇って周囲の恨みを買ったという。翌24年1月に室町幕府軍に攻められて氏憲が滅亡すると,逃亡し新田荘で蜂起したが,舞木持広と戦って捕らえられ,鎌倉で斬首された。
