Tōshō-ji (東勝寺) was the Hōjō clan's family temple (bodaiji) in Kamakura during the Kamakura period. Its founder was Taikō Gyōyū and it was constructed in 1237 by Hōjō Yasutoki in memory of his mother, who had her tomb there. According to the Taiheiki, from its foundation until the end of the Kamakura shogunate every regent (shikken) was buried there. The temple no longer exists, since it was set on fire by the Hōjō themselves when the entire family committed suicide after Nitta Yoshisada's invasion of Kamakura on July 4, 1333. Its ruins were found in the Kasaigayatsu valley in today's Ōmachi. Tōshō-ji very probably used to occupy the entire valley. Standing at the top of a narrow valley shut off at its base by the Nameri river's deep gorge and by steep hills on the other three sides, and besides offering a clear view of the only road that crossed the river, it was a fortress surely valuable to the family also from the military point of view.
