On May 22, 1333, after Nitta Yoshisada's assault on Kamakura, the last regent Hojo Takatoki retreated here and took his own life with over 870 kin and retainers. The Taiheiki records that Takatoki composed a death poem, watched his retainers commit seppuku, then cut his own belly and fell into the flames. The 150-year Kamakura shogunate ended on this ground.
