In most sports, referees are functional officials in practical uniforms. In sumo, the gyoji (行司) is something altogether different — a living embodiment of the sport's Shinto origins, dressed in robes that have changed little in 500 years, carrying tools of ancient ceremonial function, and ranked in a hierarchy that mirrors the wrestlers they oversee.
The Gyoji's Robes and Rank
The gyoji's elaborate robes are modeled on those of Shinto priests and Heian court officials. The robes signal rank through specific colors and accessories:
- Gyoji in training (lower divisions): Wear black robes with no tassels
- Juryo division gyoji: Wear robes with red and black tassels, allowed to wear footwear (tabi socks)
- Makuuchi division gyoji: Wear elaborate embroidered robes with colored tassels; the most senior wear purple
- Tate-gyoji (senior referee): Two gyoji hold the highest rank — one for east, one for west. These are the only officials allowed to carry a tantō (short sword) at their belt, symbolizing their willingness to commit ritual suicide if they make an incorrect decision. (This is symbolic; no gyoji has actually done so in modern times.)
The Gunbai Fan
The gyoji carries a gunbai (軍配) — a wooden paddle fan originally used by samurai generals to signal troop movements. The gyoji uses the gunbai to call wrestlers to the ring, signal the start of a bout, and point toward the winner at the bout's conclusion. The direction the gunbai points determines the initial ruling, which can then be challenged by the ringside judges.
The Senior Names
Like wrestlers who take ring names (shikona), gyoji take professional names that are passed down through generations. The two most prestigious names are:
- Kimura Shonosuke — the highest rank in the east
- Shikimori Inosuke — the highest rank in the west
These names have been held by numerous individual gyoji over the centuries. The current holder of the Kimura Shonosuke name officiates the final championship-deciding bout of each Makuuchi tournament.
Gyoji Careers
Gyoji join the profession in their teens and can remain active into their 60s — a career spanning decades. They do not compete; their role is purely officiating and ceremonial. Senior gyoji are revered figures in sumo culture, and their names are recognized by knowledgeable fans as readily as the wrestlers themselves.
The Yobidashi: Ring Attendants
Often confused with gyoji, the yobidashi (呼出) are the ring attendants who perform multiple essential functions: they announce the wrestlers' names in a rhythmic, traditional chant before each bout; they carry kensho (sponsorship) banners around the ring before sponsored matches; they sweep the ring surface between bouts; and they are responsible for building the dohyo itself at the start of each tournament. Their distinctive chanting announcements are one of sumo's most recognizable sounds.
