Kyokutenhō Masaru

Kyokutenhō Masaru (旭天鵬 勝; born September 13, 1974 as Nyamjavyn Tsevegnyam, Mongolian: Нямжавын Цэвэгням) in Nalaikh, Ulaanbaatar, Mongolian People’s Republic is a former professional sumo wrestler. He fought out of Ōshima stable, with the first group of Mongolians ever to join the sport in Japan.

He made his debut in March 1992, and reached the top makuuchi division in January 1998. He received seven special prizes for Fighting Spirit, and won one yūshō (or tournament), in May 2012 from the maegashira ranks, which made him at 37 the oldest first–time yūshō winner and the oldest yūshō winner in sumo history overall, until his record was beaten by fellow Mongolian Tamawashi in September 2022. His highest rank was sekiwake, which he held on three occasions.

In his exceptionally long career, he made more appearances in the top division than any other wrestler at 1470, and only Ōshio fought more than his 1870 career bouts. He was the first wrestler since the 1950s to be ranked in the top division after the age of 40.

He announced his retirement in July 2015 and declared his intention to stay in sumo as an elder, having acquired Japanese citizenship in 2005. In 2017 he became the head coach of Tomozuna stable, changing his name and the stable to Ōshima in 2022.
