(July 9, 1942 – April 14, 1996), born , was a sumo wrestler from Otaru, Hokkaidō, Japan. His highest rank was sekiwake. After his retirement he became an elder of the Japan Sumo Association and the head coach of Onaruto stable.

Career

He won the yūshō or tournament championship with a 13-2 record in the jūryō division in July 1963 and was promoted to the top makuuchi division in the following tournament in September 1963. Onaruto stable closed in December 1994 and he left the Japan Sumo Association.

The co-writer of the book died within hours of Onaruto, in the same hospital.
