In sumo wrestling, a heya is an organization of sumo wrestlers where they train and live. It can also be termed sumo-beya. All wrestlers in professional sumo must belong to one. As of 2022 there were 43 heya, each belonging to one of five ichimon. They vary in size, with the largest heya having over thirty wrestlers and smallest just one wrestler. Most heya are based in and around the Ryōgoku district of Tokyo, sumo's traditional heartland, although the high price of land has led to some newer heya being built in other parts of Tokyo or its suburbs.
