Japan Sumo Association, sometimes abbreviated JSA or NSK, is a non-profit organization headquartered in Japan. Founded in 1925, the organization reported $104.5M in revenue as of 2025. It specializes in martial arts, operating and controlling professional sumo wrestling in Japan under the jurisdiction of the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT). The Association maintains and develops sumo traditions and integrity by holding tournaments and tours. Its purposes also include developing means dedicated to the sport and maintaining, managing, and operating the facilities necessary for these activities. To support its operations, the JSA operates subsidiaries such as the Kokugikan Service Company for its economic aspects, the Sumo School for training and instruction, and the Sumo Museum to preserve and utilize sumo wrestling records and artifacts.
Kirishima, despite losing his final bout to Kotozakura at Edion Arena Osaka, concluded the meet with a 12-3 record, positioning him for an ozeki return. Previously, during the New Year Grand Sumo Tournament, preparations were underway for a sumo tour to Paris in June, following a stop in London last year, as sumo increasingly served as a tool for Japan's soft power abroad. Earlier, on January 28, the Japan Sumo Association convened a banzuke formation meeting at the Ryogoku Kokugikan in Tokyo. During this meeting, it determined the rankings for the Grand Sumo Spring Tournament, scheduled to commence on March 8 at Edion Arena Osaka, designating Kotobuki Fuji and Fujiten Seira as new Juryo wrestlers, while Shimazu Kai returned to the Juryo rank.
