1605‐51 (Keicho 10‐Keian 4)
A ronin military scholar of the early Edo period. The mastermind of the Keian Incident. He is said to have been born as the son of a dyer in Yui, Suruga, or Miyagasaki, Suruga. He went to Edo and taught military science to vassals of shogunate vassals and feudal lords at a back store in Renjaku-cho, Kanda, and gathered many disciples. However, he did not accept invitations from daimyo, and only took on one daimyo as a disciple, other than ITAKURA Shigemasa. In 1651 (Keian 4), he planned a rebellion against the shogunate, criticizing the shogunate and saving the hatamoto, and gathered many ronin. In July, he went to Sunpu with nine of his comrades to put his plan into action, and tried to steal the money left by Tokugawa Ieyasu from Mount Kuno, but the plan was discovered before he could carry it out, and he was surrounded by the men of the Sunpu town magistrate while at the Umeya inn in Sunpu, and took his own life on the morning of the 26th.
