A toshiyori (年寄) is a sumo elder of the Japan Sumo Association. Also known as oyakata, 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.
To become an elder, a retiring wrestler must be a Japanese citizen. This regulation dates from September 1976 and was widely thought to be a result of the success of the Hawaiian Takamiyama Daigoro, who had become the first foreign wrestler to win a championship in 1972, and had expressed interest in becoming an elder. Takamiyama ultimately became a Japanese citizen in June 1980 and did become the first foreign-born elder upon his retirement in 1984. Elders must also have fought at least twenty tournaments in the top makuuchi division or thirty as a sekitori (makuuchi or jūryō division). The rules were modified in November 2013 to allow membership after only 28 sekitori tournaments in certain circumstances, and former wrestlers who are inheriting an existing stable need only 12 makuuchi tournaments or 20 in jūryō. However, membership can only be obtained by purchasing or inheriting toshiyori-kabu, or elder stock, in the Japan Sumo Association. There are only 105 shares available for purchase, and the increasing lifespan of elders has meant that they take longer to become vacant. As a result, their decreasing availability has caused their price to greatly increase, with stock now reportedly selling for up to 500 million yen. Often the only way wrestlers, even very successful ones, can afford a share is if they have a large and wealthy group of supporters and financial backers.
An exception to the purchase requirement is made for the most successful former yokozuna, sometimes referred to as dai-yokozuna, who may be offered a one-time membership of the Association, or ichidai-toshiyori status. Three former wrestlers, Taihō, Kitanoumi and Takanohana obtained this status. A fourth, Chiyonofuji, was offered this status but preferred a normal share. These four all achieved more than twenty tournament championships in their active career.
