In professional sumo wrestling, a wrestler’s training stable is called a heya.
A heya is the community where wrestlers live, train, eat, and develop under the supervision of a stablemaster. The word literally means “room,” but in sumo it refers to an organized stable rather than just a physical chamber. Stablemates commonly share training and daily duties.
Heya are affiliated with one of the sport’s larger ichimon, or stable groups. These relationships affect administration and competition, although wrestlers from the same stable generally do not meet each other in official tournament bouts. A stable may also employ coaches and support staff.
“Stable” is the usual English translation, while heya is the Japanese term. It should not be confused with the dohyo, which is the ring, or the banzuke, which is the ranking list.
