Kinryūzan Shakuman-in Endon Hōkai-ji (金龍山釈満院円頓宝戒寺) is a Buddhist temple in Kamakura, Kanagawa Prefecture, Japan. Often called Hagidera (萩寺), or "bush-clover temple", because those flowers are numerous in its garden, its existence is directly linked to a famous tragedy that on July 4, 1333 wiped out almost the entire Hōjō clan, ruler of Japan for 135 years. The temple was founded expressly to enshrine the souls of the 870 members (men, women and children) of the clan who, in accordance with the samurai code of honor, committed suicide on that day at their family temple (bodaiji) of Tōshō-ji to escape defeat. Together with ancient Sugimoto-dera, Hōkai-ji is the only temple of the Tendai denomination in Kamakura.
