Naruto stable (鳴戸部屋 Naruto-beya) is a stable of sumo wrestlers, part of the Nishonoseki or group of stables, and founded by former sumo wrestler Kotoōshū Katsunori on 1 April 2017.
As of May 2026, the stable has 13 active wrestlers.
History Naruto stable was established on 1 April 2017 by the Bulgarian-born former Kotoōshū Katsunori, who branched out from Sadogatake stable. It is based in Sumida, Tokyo. One of the stable's early recruits was also a Bulgarian – former junior wrestling champion Ventsislav Katsarov (Torakio Daiki) who retired in April 2019 and returned to Bulgaria. The opening ceremony of the stable was attended by one hundred people including Kotoōshū's former stablemate Kotoshōgiku. Kotoōshū commented, "I want to nurture a wrestler who will eclipse me."
Kotoōshū became a naturalized Japanese citizen two months after his retirement in March 2014. His official name is Andō Karoyan. He is the first European-born stablemaster. He is also only the third foreign-born wrestler to open his own stable after Takamiyama and Musashimaru.Tomozuna Oyakata (the Mongolian born Kyokutenho) is also a stablemaster, but inherited an existing stable rather than building a new one.
According to a report in May 2018, some wrestlers said that they chose Naruto stable because they had the most information when they searched the internet.ネット情報発信量が多いから「鳴戸部屋」 日刊スポーツ 2018年5月22日10時0分（日刊スポーツ新聞社、2019年2月18日閲覧） Naruto stable is not related to Tagonoura stable which had the same name until 2013.
Naruto suspended one of his wrestlers (reported to be a 20-year-old -level wrestler) from the January 2019 tournament after it emerged he had choked a junior wrestler as a punishment. This is the first time the Compliance Committee and the Anti-Violence Provisions, which were established in December 2018, were applied. On 19 February 2019 an apology statement was posted on Naruto's official blog and the Twitter page of his stable: "To all of you who always support us. This time, I was very sorry for the trouble that occurred in the stable. We will reflect firmly and take the disposition of the Sumo Association seriously, and will provide guidance and supervision to prevent this from happening in the future."
