About Matsudono Moroie
- Matsudono Moroie (?? ??, July 12, 1172 – November 11, 1238), third son of Matsudono Motofusa, was a kugyo (high-ranking Japanese official) from the late Heian period to the early Kamakura period.
- Regent Fujiwara no Tadataka and Buddhist monks Gyoi and Jitsuson are his stepbrothers. Though he was not first-born, in 1179 at age of 8 he was promoted to gon-chunagon, one of Daijo-kan due to the political tension between Emperor Go-Shirakawa and Taira no Kiyomori.
- However, this caused backlash from Kiyomori, leading to the Jisho coup in the same year. In 1232, he ordained as a Buddhist monk and took the Dharma name Daishin (??).
