Masako was the oldest child of fifteen.[1] She was instructed in horseback riding, hunting, fishing, and she ate with men rather than with the women of the household.[citation needed] Her brother, Hōjō Yoshitoki, born in 1163 would eventually become the second Hōjō shikken (regent) of the Kamakura shogunate and head of the Hōjō clan. Another of her brothers, Hōjō Tokifusa, would become a member of the Rokuhara Tandai.
