Tochigiyama won a third championship during his first tournament as yokozuna. In June 1931, Tochigiyama took part in the first Dai-Nippon Rikishi Senshuken (大日本角力選手権), special sumo tournament. After he won his first two championships at ōzeki without suffering a single defeat, he was promoted to yokozuna in February 1918. He also won the following two tournaments, meaning he achieved five consecutive championships between May 1917 and May 1919.
