Born in Anamizu, Hosu District, as an amateur he won eleven sumo titles, including collegiate and amateur yokozuna, while studying at Nihon University. He also served as captain of the school sumo team. He was recruited by the former sekiwakeAnnenyama of the Tatsunami stable. Yamazaki had stayed at the heya while taking part in junior high school competitions, and he had also met the former Tatsunami stable wrestler Wakanami as an infant, being held in his arms for a photograph. As an amateur champion he was given makushita tsukedashistatus and made his debut in the third highest makushita division. His first tournament was in January 1989 and after two consecutive yūshō with perfect 7-0 records in January and March 1990 he was promoted to the second highest jūryō division, becoming the first sekitori from Tatsunami stable since the abrupt departure of yokozunaFutahaguro in 1987. He changed his shikona or fighting name from his own surname to Daishōyama at this point. Daishōyama made his debut in the top makuuchi division in September 1990, and made a kachi-koshi winning score along with three other makuuchi debutants, Akebono, Wakahanada and Takatoriki. This marked the first time that four wrestlers making their top division debuts at the same time had all come through with winning records. In January 1991 he reached what was to be his highest rank of maegashira 2 and earned his first kinboshi for defeating yokozuna Hokutoumi. He was to repeat this upset in July 1991 and also defeated yokozunaŌnokuni in that tournament. In January 1993 he had slipped to maegashira 14 in the banzuke rankings but responded with his best ever top division score, winning twelve bouts, defeating Konishiki and Takahanada amongst others and finishing runner-up to Akebono, who was promoted to yokozuna after the tournament. Daishōyama was rewarded with what was to be his only sanshō award, for Fighting Spirit. Daishōyama had had longstanding hip problems since his professional debut, and after missing two tournaments in 1994 through injury he fell back to the jūryō division. After being forced to sit out the September 1995 tournament as well he was demoted to the makushita division and retired from sumo in November without competing in any more bouts.
Retirement from sumo
Having fought in 33 tournaments as a sekitori, Daishōyama was qualified to become a toshiyori, or elder of the Japan Sumo Association, and he purchased the Oitekaze name. In May 1998 he branched out from Tatsunami stable, where he had been working as a coach, and opened up his own Oitekaze stable. His first top division wrestler was Hayateumi in 2000 and he was followed by Hamanishikiin 2001. Both are former Nihon University competitors. He also recruited the Georgian wrestler Kokkai who reached makuuchi in 2004. More recent Nihon University recruits include the popular Endō in 2013 and Daishōmaru in 2014, both of whom have reached the top division. He produced another top division wrestler Daieishō in 2015, who has a non-collegiate background.
