The 1582 Battle of Tenmokuzan (天目山の戦い, Tenmokuzan no Tatakai) in Japan, is regarded as the last stand of the Takeda clan. This was the final attempt by Takeda Katsuyori to resist the forces of Oda Nobunaga, who had been campaigning against him for some time. In his bid to hide from his pursuers, Katsuyori burned his fortress at Shinpu Castle and fled into the mountains, to another Takeda stronghold, called Iwadono, held by Oyamada Nobushige, an old Takeda retainer. Katsuyori was denied entry by Oyamada, and committed suicide with his wife, while the last remnant of his army held off their pursuers.
