His highest rank was ōzeki. After his retirement he was the head coach of Mihogaseki stable and produced yokozuna Kitanoumi among other wrestlers. Born Kumiaki Sawaka, he joined Dewanoumi stable in 1935 and initially fought under the shikona of Hamanishiki, before changing to Masuiyama in 1937.
After winning the makushita tournament championship or yūshō in 1939 he was promoted to jūryō and only two tournaments later, after picking up another championship, he was promoted to the top makuuchi division for the January 1941 tournament.
In January 1942 he defeated yokozuna Haguroyama to earn his first gold star or kinboshi. In the first postwar tournament held in a bomb-damaged Kokugikan in June 1945 he could manage only two wins and dropped back to the maegashira ranks, but he was runner-up to Haguroyama in November 1946 with a fine 11-2 record.
He took advantage of the poor condition of the three yokozuna and finished with a 10-1 record, defeating ōzeki Azumafuji in a playoff. After the tournament Azumafuji was promoted to yokozuna and Masuiyama was elevated to ōzeki.
In his second tournament at ōzeki rank Masuiyama took his second and final championship, defeating yokozuna Haguroyama, Azumafuji and Maedayama on three consecutive days to finish 13-2.
This was to be the last tourney Masuiyama was to complete. After pulling out of the next two tournaments through injury he retired in January 1950 at the age of 30, having spent only four tournaments at ōzeki rank. He became head coach of the small Mihogaseki stable.
