Onoe stable (Japanese: 尾上部屋, Hepburn: Onoe-beya) is a stable of sumo wrestlers, part of the Dewanoumi group of stables. It is situated in Tokyo's Ōta ward. It was established in August 2006 by former komusubi Hamanoshima, who branched off from Mihogaseki stable and took several of its leading wrestlers with him. For its first few years, Onoe stable was located in what was essentially a "converted garage," where numerous miscellaneous items were only about a meter away from the edge of the practice ring's straw bales.In November 2007, it had eight wrestlers, half of whom were ranked as sekitori (in the top two divisions). In 2011, three of its wrestlers, former maegashira ranked Sakaizawa, and Yamamotoyama and the former jūryō Shirononami, were forced to retire after being found guilty by the Japan Sumo Association of match-fixing. The retirements of Satoyama in November 2018 and Tenkaihō in March 2019 left the stable with no wrestlers in the top two divisions until Ryūkō reached jūryō in July 2019, but he suddenly left sumo in September 2021 due to an ankle injury. As of January 2023, Onoe stable has 12 wrestlers. It has posted regular updates from its Facebook page since training at the stable was curtailed due to the COVID-19 pandemic.
