Sumo - Professional Sumo

Professional Sumo

Professional sumo is organized by the Japan Sumo Association. The members of the association, called oyakata, are all former wrestlers, and are the only people entitled to train new wrestlers. All practicing wrestlers are members of a training stable (heya) run by one of the oyakata, who is the stablemaster for the wrestlers under him. Currently there are 47 training stables for about 660 wrestlers.

All sumo wrestlers take wrestling names called shikona (しこ名), which may or may not be related to their real names. Often wrestlers have little choice in their name, which is given to them by their trainer (or stablemaster), or by a supporter or family member who encouraged them into the sport. This is particularly true of foreign-born wrestlers. A wrestler may change his wrestling name several times during his sumo career.

Sumo wrestling is a strict hierarchy based on sporting merit. The wrestlers are ranked according to a system that dates back hundreds of years, to the Edo period. Wrestlers are promoted or demoted according to their performance in six official tournaments held throughout the year. A carefully prepared banzuke listing the full hierarchy is published two weeks prior to each sumo tournament.
