Hōjō Masako
Before the opening of the Entrances, access on land was so difficult that the Azuma Kagami reports that Hōjō Masako came back to Kamakura from a visit to Sōtōzan temple in Izu bypassing by boat the impassable Inamuragasaki cape and arriving in Yuigahama. Again according to the Azuma Kagami, the first of the Kamakura "shōguns", Minamoto no Yoritomo, chose it as a base partly because it was his ancestors' land (his "yukari no chi"), partly because of these physical characteristics.
