system has been in place, three former wrestlers (Taihō, Kitanoumi and Takanohana) have obtained this status. A fourth, Chiyonofuji, was offered this status but preferred a normal share and became Kokonoe-oyakata. These four all achieved more than twenty tournament championships in their active careers. In October 2021, yokozuna Hakuhō, the Emperor's Cup number record holder, was however denied the ichidai toshiyori kabu and Masayuki Yamauchi (a Yokozuna Deliberation Council member) declared to a press conference that "no such system exists". The members of the Association receive a salary and are expected to assist in the running of their stable and the Association, from selling tickets and security work at the most junior level, to taking charge of one of the Association departments as a director. These members are also the only persons given the authority to train new sumo wrestlers. They do this by opening or taking over a training stable, or heya (changed to beya as a suffix) which will take the same name as the founder's elder name. Thus Dewanoumi-oyakata will be the owner of Dewanoumi-beya. Typically about 50% of the Association members have their own stable, while the rest are required to be affiliated with one and assist the principal owner. It is common for the most senior members of the Association to concentrate on their Association responsibilities and pass the day-to-day management of a stable to another. If a senior oyakata wishes to do this, the two may elect to swap names so that the stable can keep the more prestigious name. A recent example was in 1996, when the Association's chairman Dewanoumi-oyakata (former yokozuna Sadanoyama), swapped names with Sakaigawa-oyakata (former sekiwake Washūyama) who took over the running of Dewanoumi stable. The Association members are also split into various ranks. A new retiree will begin his career as a coach at toshiyori rank (commonly called oyakata), except for former ōzeki and yokozuna who are automatically granted Committee Member rank. The most senior Association members are Committee Members. All members are required to retire when they reach the age of sixty five (with a possible five year extension if approved by the board of directors), after which they can pass their name to another, provided that person meets the Association's eligibility requirements. In the case of a one-time membership mentioned above the name merely lapses. Like the toshiyori kabu system there can be only a limited number
