He was born Satō Fukumatsu. In the fall of 1909, he joined Dewanoumi stable. He made his professional debut in June 1910 using the shikona name Iwategawa. However, he was punched by Kyushuzan Juro and escaped from Tokyo sumo in May 1912. He did not abandon the idea of becoming a wrestler and moved to Osaka sumo. In January 1913 he began using the ring name Miyagiyama, before changing it to Miyagiyama Fukumatsu in May 1914. Miyagiyama reached the top makuuchi division in 1916 and he was promoted to ōzeki after only 2 tournaments. In January 1920, he won his first championship with an 8-1-1draw record. In March 1921, he fought against wrestlers in Tokyo sumo and defeated sekiwake Genjiyama, ōzeki Tsunenohana, yokozunaŌnishiki and Kyushuzan. Around this time he reconciled with Kyushuzan. In June 1921, he won the championship with an 8–2 record. In January 1922, he won the championship with a perfect 10–0 record. After winning two consecutive championships, he was awarded a yokozuna licence. He was absent from two tournaments in 1923 due to a phlegmon on the middle finger of his right hand. In January 1926, he won the championship with a 9–1 record. In 1927, Osaka Sumo Association disbanded and its wrestlers merged with Tokyo sumo. At that time, Osaka sumo's level was very low and he was not considered to be strong enough. However, he felt he had to save the honor of Osaka sumo as yokozuna. Although his strength had already declined, he fought tooth and nail and won 2 championships in Tokyo sumo as part of the Osaka contingent of wrestlers. The first of these, in January 1927, was the first tournament to be held under the auspices of the Dai Nihon Ozumo Kyokai. Considering that he had been retained as a yokozuna simply because there was no precedent for demoting one and to allow Osaka sumo to save face, it was regarded as a sensational result. After his retirement, he became the 6th head coach of Shibatayama stable. The stable was closed after his death. Afterward, the 62nd yokozunaŌnokuni became the 12th holder of the Shibatayama name and he opened the modern Shibatayama stable.

*Championships for the best record in a tournament were not recognized or awarded in Osaka sumo before its merger with Tokyo sumo, and the unofficial championships above are historically conferred. For more information, see yūshō.
