Kotō Takefuji
Kotō Takefuji was a younger son of the Nagato warlord Kotō Takezane and younger brother of Takemura. During the Kannō Disturbance the clan split over allegiance: its heads Takenao and Yoshitake backed the Muromachi shogunate and Isshiki Noriuji.
Takefuji instead sided with Ashikaga Tadafuyu, Takauji's disaffected son, and the Southern Court. In 1352 Tadafuyu was defeated by Isshiki at Dazaifu and withdrew to Nagato, where Takefuji's branch held sway.
