[Hōjō] Yoshitoki had considerable bravery, cunning, and tolerance, surpassing others in such aspects. During the rebellion of Wada Yoshimori, messengers came with urgent news one after another. [Hōjō] Yoshitoki was playing Go with a guest at the time, but his tone and facial expression never changed. He slowly finished the game, then changed his clothes and headed to his office to direct generals. Thus, he defeated [Wada] Yoshimori. At the time, he showed humility on the outside, but harbored treachery in the inside. Every time he was transferred to a new title, he would not style himself with the new title, and when he was made provisional Mayor of the Right Capital District, he still called himself by his former title. After [Minamoto] Yoritomo died, he seized absolute control of the military. He could depose and enthrone emperors as well as promote and demote ministers. The power of the empire was thus concentrated with him. This is why he was assassinated by a close retainer.
