His heir, [[Takeda Mitsuo|Mitsuo]] [光和], died suddenly in 1535. Mitsuo's adopted son [[Takeda Motosane|Motosane]] [信実] quit Kanayama in 1541 when it was threatened by the Môri and Ôuchi in the wake of the Amako's defeat in Aki Province at the [[Battle of Yoshida-Koriyama]] [吉田郡山城の戦い]. Motosane fled to [[Izumo province]] and Kanayama surrendered.
