Ashikaga Motoyori served as a bushō and the second Koga kubō in Shimōsa Province during the Sengoku period.
Motoyori was the son of Ashikaga Masauji. Based on a study of his activities, he was likely born in the first half of the Meiō era (1492 to 1501) and completed his coming-of-age ceremony by 1513.
In regard to the conflict between his father (Masauji) and his older brother (Ashikaga Takamoto), Motoyori initially sided with his father and operated from Hitachi Province; however, by 1516, he switched his allegiance to Takamoto. Motoyori joined with Makabe Munemoto and Daijō Tadamoto and temporarily deployed near the Namekata District. Thereafter, Motoyori continually sided with Takamoto in conflicts between Takamoto and his brother, Ashikaga Yoshiaki, as well as between Takamoto and Takamoto’s son, Ashikaga Haruuji. In 1531, Motoyori came under the command of Yoshiaki after Yoshiaki adopted the title of Oyumi kubō and raised arms from the Bōsō Peninsula in a bid to overcome an earlier loss to Takamoto. By the summer of 1531, Motoyori was under Takamoto, but as soon as Haruuji achieved imminent victory by the end of summer, Motoyori joined Chiba Katsutane to deploy with the Ida clan.
In 1538, Motoyori supported Yoshiaki in battle against Hōjō Ujitsuna, but died in action in the First Battle of Kōnodai.
