Mōri Sadachika

Mōri Sadachika (died 1351) was a warrior of the Mōri clan of Ōe descent, active from the late Kamakura period into the Nanboku-chō wars. The son of Mōri Tokichika, he likely received the character sada in his name from the regent Hōjō Sadatoki.

In 1334, after his father retired to Yoshida in Aki Province, Sadachika and his heir Chikahira rose in Echigo against Ashikaga Takauji, backing a Daikakuji-line prince. The revolt failed; Sadachika took the tonsure as a follower of Emperor Go-Daigo, calling himself Rōjō.
