The Japan Sumo Association is the body that operates and controls professional sumo wrestling in Japan under the jurisdiction of the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT). Rikishi, gyōji (referees), tokoyama (hairdressers), and yobidashi (ushers/handymen), are all on the Association's payroll, but the organisation is run entirely by toshiyori (elders). The organization has its headquarters in Yokoami, Sumida, Tokyo.
A toshiyori (年寄) is a sumo elder of the Japan Sumo Association (JSA). Also known as oyakata (親方), former wrestlers who reached a sufficiently high rank are the only people eligible. The benefits are considerable, as only toshiyori are allowed to run and coach in sumo stables, known as heya, and they are also the only former wrestlers given retirement pay.
