Hōjō Tokimasa
Minamoto no Yoriie was born to Hōjō Masako at Hiki Yoshikazu's residence in Kamakura. Before he was born, his father Yoritomo had Hōjō Tokimasa and his men carry stones to build the Dankazura on Wakamiya Ōji to pray for the child's safe delivery. When Yoriie later himself had an heir, Ichiman, the child was also born at the Hiki mansion to Hiki's daughter Wakasa no Tsubone, a fact which further consolidated an already strong emotional bond. From this relationship Hiki gained considerable influence when Yoriie became shōgun, incurring the hostility of Hōjō Tokimasa, who was instead close to Yoriie's younger brother Senman (future third shōgun Sanetomo), and who was in his turn trying to leverage that relationship for political advantage. His childhood name was Manju (万寿).
