In 1333, Emperor Go-Daigo escaped from Oki with the help of Nawa Nagatoshi and his family, raising an army at Senjo Mountain in Hōki Province (the modern town of Kotoura in Tōhaku District, Tottori Prefecture). Ashikaga Takauji, who had been sent by the shogunate to find and destroy this army, sided with the emperor and captured the Rokuhara Tandai. Immediately following this, Nitta Yoshisada, who had raised an army in the east, laid siege to Kamakura. When the city finally fell to Nitta, Hōjō Takatoki, the shogunal regent, fled to Tōshō temple, where he and his entire family committed suicide. This ended Hōjō power and paved the way for a new military regime.
