Honinbo Dochi (本因坊道知 Hon'inbō Dōchi, 1690-1727) was the fifth head of the Honinbo house.
Meijin Dochi was born in Tokyo in 1690 and learned to play Go at 7. Two years later he became a pupil of Honinbo Dosaku, Meijin. After the death of his master and teacher in 1702, he was kept under guardianship of Inseki 8-dan(later Meijin), 4th master of Inouye School.
It was a pity for the young boy that he had to follow his guardian's intention perfectly; sometimes he was obliged to be beaten in the pre-arranged games. Probably he was instructed by his senior master to do so. It was a bad time for Go. In 1719 he became 8-dan, becoming Meijin Godokoro in 1721.
