Tomozuna stable
Having fought in 33 tournaments as a "sekitori", Daishōyama was qualified to become a "toshiyori", or elder of the Japan Sumo Association, and he acquired the Oitekaze name, having married the daughter of the previous Oitekaze (former "maegashira" Oiteyama). Initially a coach at Tatsunami stable, in 1997 he moved to Tomozuna stable. In October 1998 he left Tomozuna to branch out and open up his own Oitekaze stable. His first top division wrestler was Hayateumi in 2000 and he was followed by Hamanishiki in 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, Daishōmaru and Tsurugisho in 2014, Tobizaru in 2015 and Daiamami in 2016, all of whom have reached the top division. He produced another top division wrestler Daieishō in 2015, who has a non-collegiate background, and won a yūshō in January 2021.
