Japan Sumo Association, a non-profit organization headquartered in Japan, was founded in 1925 and reported $104.5M in revenue as of 2025. The association operates and controls professional sumo wrestling in Japan under the jurisdiction of the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT). It maintains and develops sumo traditions and integrity by holding tournaments and tours, while also developing means dedicated to the martial art and managing facilities necessary for these activities. To support its operations, the Japan Sumo Association operates subsidiaries including the Kokugikan Service Company for economic organization, the Sumo School for training and instruction, and the Sumo Museum for the preservation and utilization of sumo wrestling records and artefacts.
On April 24, 2026, Nobuyoshi Hakkaku, the six-time appointed Chairman of the Japanese Sumo Association, received the Freedom of the City of London, expressing deep honor on behalf of all sumo wrestlers and members. This followed the Japan Sumo Association's decision on April 9, 2026, to demote stablemaster Isegahama, formerly grand champion Terunofuji, by two ranks and cut his pay by 10% for three months. This action stemmed from violence toward a wrestler in his stable. The association also issued a stern warning to the wrestler Hakunofuji for an inappropriate act against a woman, which had precipitated the violence. Previously, on February 3, 2026, sumo was highlighted as part of Japan’s "soft power" arsenal overseas, with preparations underway for a June tour to Paris, following a previous stop in London last year.
