Source-derived summary

Musōyama Masashi (born February 14, 1972, as Takehito Oso) is a former sumo wrestler from Mito, Ibaraki, Japan. A former amateur champion, he turned professional in January 1993, and he won promotion to the top makuuchi division in just four tournaments. He won thirteen special prizes and spent a total of 31 tournaments at komusubi and sekiwake before finally reaching the second highest rank of ōzeki in 2000, shortly after winning his only top division tournament championship or yūshō. He retired in 2004. He is now the head coach of Fujishima stable.

Early career

Oso was interested in sumo from a young age, as his father was the director of the Ibaraki Prefecture sumo association. He won national amateur titles at high school and at Senshu University, where he was a rival of Tosanoumi. He made his professional debut in January 1993 in the third makushita division, as due to his amateur achievements he had been given makushita tsukedashi status. He breezed through makushita undefeated with two consecutive 7–0 scores to earn promotion to the second jūryō division, whereupon he changed his shikona from Oso to Musōyama, meaning "twin warrior mountain." He made his debut in the top makuuchi division in September 1993. It took him only seven tournaments from his professional debut to make the san'yaku ranks, debuting at sekiwake in March 1994.

Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Musōyama Masashi”, the useful work is to connect “sumo wrestler” to the records capable of establishing context and consequence.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Mar 26, 2026. The linked authority identifier is Q1488482. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1972, 1993, 2000 and 2004.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
