Born in
Himeji, he was the son of former
ōzeki Masuiyama Daishirō I, and the grandson of a
komusubi in
Osaka sumo,
Tamanomori. He was a talented swimmer at school but wanted to follow his father into sumo. Initially turned down because of his size, he eventually persuaded his father to let him join his
Mihogaseki stable in January 1967. He began at the same time as
Kitanoumi, a future
yokozuna. He began fighting under the name Suiryū (his own surname was being used by another wrestler), adopting the Masuiyama
shikona the following year. He reached
sekitori status in July 1969 upon promotion to the
jūryō division and reached the top
makuuchi division for the first time in March 1970. Weighing barely 100 kg, and prone to injury, he was not able to establish himself in the division until 1972, temporarily dropping back to
jūryō where he won his only
yūshō or tournament championship in January of that year. In November 1972, he won the first of his five
Ginō-shō or Technique
prizes and earned promotion to
komusubi. He was demoted after only one tournament and mostly remained in the
maegashira ranks for the next few years. In May 1974, he scored 12 wins and was a tournament runner-up behind stablemate Kitanoumi. In July 1978, he finally earned promotion to the third highest
sekiwake rank, but once again was unable to maintain it, dropping back to
maegashira level. At the end of 1979, he returned to
sekiwake and scored 11 wins. In January 1980, he was again a tournament runner-up, this time to
yokozuna Mienoumi, and after the tournament he was promoted to
ōzeki. It had taken him 60 tournaments to get there from his top-division debut, a record, and at thirty one years two months he was also the oldest to reach the rank since the introduction of the six-tournaments-a-year system in 1958 (The latter record was broken by
Kotomitsuki in July 2007). Masuiyama and Mihogaseki Oyakata became the first father and son
ōzeki in sumo history. His
ōzeki career was brief, and he announced his retirement during the March 1981 tournament. ==Retirement from sumo==
