Japan Sumo Association, a non-profit organization headquartered in Japan, was founded in 1925, focusing on martial arts. The organization reported $104.5M in revenue as of 2025. It operates and controls professional sumo wrestling in Japan under the jurisdiction of the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT), maintaining and developing sumo traditions and integrity by holding tournaments and tours. The Association also develops means dedicated to the sport and maintains, manages, and operates the facilities necessary for these activities, operating subsidiaries such as the Kokugikan Service Company to organize its economic aspects, the Sumo School to organize training and instruction, and the Sumo Museum to preserve and utilize sumo wrestling records and artefacts.
On October 1, 2026, the Japan Sumo Association announced plans for a three-day exhibition in Bangkok, Thailand, scheduled for June 11 of the following year. This event marks the association's first exhibition in Thailand and its third consecutive overseas performance, following London last year and Paris this year, and will commemorate the 140th anniversary of diplomatic relations between Japan and Thailand in 2027. Previously, on May 11, TUDOR announced a new partnership with the Japan Sumo Association, integrating with its GrandSumo universe. Earlier, on April 24, Japanese champion sumo wrestler and six-time Chairman of the Japanese Sumo Association, Nobuyoshi Hakkaku, received the Freedom of the City of London. This followed the association's decision on April 9 to demote former yokozuna grand champion Terunofuji, now stablemaster Isegahama, by two ranks and reduce his pay by 10% for three months, after he assaulted a wrestler under his tutelage. The association also issued a stern warning to wrestler Hakunofuji for an inappropriate act against a woman that led to the violence.
