Long before the temple existed, this valley was known as Kamegayatsu, and it was family land for the Minamoto clan. The mountain behind it is Genji-yama, and Yoritomo's father, Minamoto no Yoshitomo, once had a residence here. In 1180, when Minamoto no Yoritomo first entered Kamakura, he planned to build his residence, the seat of his new government, on this very spot. He changed his mind for two reasons. A man named Okazaki Yoshizane had already raised a hall here to pray for the soul of Yoshitomo, and the land was simply too narrow. So the shogunate took root elsewhere, and this ground stayed a place of memory. The temple came later. Yoritomo died in 1199, reportedly after a fall from his horse. In 1200 his widow, Hōjō Masako, founded Jufuku-ji to honor him, on the old Yoshitomo estate. She invited the monk Eisai to be the first abbot. Masako herself, who lived from 1157 to 1225, became so famous in Japan that she turns up in television period dramas to this day.
