In 1991, Tsevegnyam came to Japan with five other Mongolian wrestlers, including Kyokushūzan, joining Ōshima stable. They were the first Mongolians to join professional sumo. In Mongolia he had had little experience of wrestling or judo, concentrating on basketball in junior high school. Six months after they came to Japan, due to cultural difference, language problems, and the extremely harsh training methods used in sumo, Kyokutenhō, Kyokushūzan and three others ran away and sought refuge in the Mongolian embassy, but he was persuaded by Kyokutenzan to return to his stable.
