is a stable of sumo wrestlers, one of the Nishonoseki or group of stables. It was founded in its modern form on 1 October 1994 by Masurao Hiroo, who branched off from the now defunct Oshiogawa stable.
As of May 2026, the stable has 13 active wrestlers.
History The stable first wrestler to reach the top division was Katayama in 2005. The now retired Wakakōyū reached in 2012, as did Ōnoshō in 2017. The stable's most successful foreign recruit has been the Russian former Amūru, who retired in 2018. In January 2010 the stable, along with the Takanohana, Ōtake and Magaki stable, was forced to leave the Nishonoseki after former Takanohana declared his intention to run as an unofficial candidate in the elections to the Sumo Association's board of directors. The ejected stables formed their own group, which gained status of its own in 2014. This was dissolved in 2018, with the Ōnomatsu, Ōtake and Chiganoura stables briefly forming Ōnomatsu before aligning themselves once again with the Nishonoseki group. Masurao resigned from the Japan Sumo Association for health reasons on 26 September 2019 and was replaced by the former Daidō.
On 26 December, the Japan Sumo Association announced the stable recruited Batjargal Choijirsuren, a Mongolian-born Student Yokozuna, and allowed him to use the system and enter his first official tournament at the rank of makushita 15. Now wrestling under the of Ōnokatsu, he made his competitive debut at the November 2023 tournament.
