A sumo gyōji, the 37th Shikimori Inosuke.

A Gyōji (行司) is a referee in professional sumo wrestling in Japan.

Gyōji usually enter the sumo world as teenagers and remain employees of the Sumo Association until they retire aged 65.


The gyōji's principal and most obvious task is to referee bouts between sumo wrestlers. After the yobidashi has called them into the ring it is his responsibility to watch over the wrestlers as they go through the initial prebout staring contests, and then coordinate the initial charge (or tachi-ai) between the wrestlers. He will indicate that the preparation time (four minutes for the top division) is up by saying "mattanashi kamaete" ("time's up, prepare yourselves") and signal with his fan that the bout is to begin (although it is the wrestlers that ultimately determine the exact point at which the tachi-ai is initiated). During the bout he is supposed to keep the wrestlers informed that the bout is still live (it is possible for a wrestler to brush his foot outside the ring without realising it). He does this by shouting "nokotta nokotta!" (残った、残った!), which in English is roughly, "You're still in it! You're still in it!" The gyōji also has the responsibility to encourage the wrestlers to get a move on when action between them has completely stopped, for instance, when both of them are locked up on each other's mawashi in the middle of the ring. He will do this by shouting "hakkei yoi, eh! hakkei yoi, eh!" Furthermore, when a wrestler has apparently fallen to the clay, the gyoji is expected to determine the winner of the bout. His most obvious accessory is a solid wooden war-fan, called a gunbai which he uses in the prebout ritual and in pointing to the winner's side at the end of each bout.

The gyōji's decision as to the winner of the bout can be called into question by one of the five referees, or shimpan, who sit around the ring. If they dispute the result they hold a mono-ii (lit: a talk about things) in the centre of the ring, aided through an earpiece to a further two shimpan in a video room. They can confirm the decision of the gyōji, overturn it, or order a rematch. The gyōji is not expected to take part in the discussion during a mono-ii unless asked to do so. In many cases, a match may be too close to call, or the gyōji may not have managed to get a clear view of the end of the bout. Regardless, he is still obliged to make a split second decision as to his choice of "winner". This creates pressure for a gyōji, especially considering that a reversed decision is like a black mark: too many and it may affect his future career.

In addition to refereeing matches, gyōji have a number of other responsibilities, including the calligraphy in the writing of the wrestlers ranking list, called the banzuke. They also are responsible for keeping the records of wrestler results, and in determining the technique used by a particular wrestler in winning a bout. All gyōji are associated with one of the heya or training stables throughout their career and will be expected to assist their stablemaster also.


Career progression is based on a ranking system similar in name to that used for sumo wrestlers (see sumo). The rank nominally represents the rank of wrestler that they are qualified to referee for. However, unlike sumo wrestlers, promotion is to a large degree determined on length of service. Typically a gyōji's promotion is only held up if he has made too many mistakes in determining the outcome of matches, except for the topmost rank where leadership skills may play a more significant role.

The tate rank denotes the two chief referees.

Top gyōji (makushita ranked and above) are assigned tsukebito, or personal attendants in their stable, just as top wrestlers (sekitori) are. These may be junior referees or lower-ranked wrestlers. There is a superstition in the sumo world that a wrestler serving a gyōji will not go on to have a successful career.[1]


The 33rd (out of 36) Kimura Shōnosuke, the top-ranked gyōji, indicated by the solid purple tassles on his outfit.

When refereeing matches senior gyōji wear elaborate silk outfits, based on medieval Japanese costume from the Ashikaga period.

Like the sumo wrestlers, gyōji ranked at makushita level and below wear a much simpler outfit than those ranked above them. It is made of cotton rather than silk and is about knee length. The outfit also incorporates a number of rosettes, and tassels which are normally green, but can be black in colour. Within the dohyō they are also expected to go barefoot.

On promotion to lowest senior rank of jūryō the gyōji will change into the more elaborate full length silk outfit. The rosettes and tassels on his outfit will also change to be green and white. He is also entitled to wear tabi on his feet.

As he moves further up the ranks there are additional small changes:

Makuuchi ranked gyōji merely need to change the colour of the rosettes and tassels to orange and white.

On achievement of san'yaku rank the rosettes and tassels become solid orange and he also is allowed to wear straw zōri on his feet in addition to the tabi.

As described above, the two holders of the topmost rank, equivalent to yokozuna and ōzeki, are the tate-gyōji. The rosettes and tassels are purple and white for the lower-ranked tate-gyōji and solid purple for the higher-ranked one. Furthermore both the top two gyōji carry a tantō (a knife) visible in the belt of the outfit. This is supposed to represent the seriousness of the decisions they must make in determining the outcome of a bout, and their preparedness to commit seppuku if they make a mistake. In reality if one of the two top-ranked gyōji has his decision as to the victor of a bout overturned by the shimpan then he is expected to tender his resignation instead. However, the resignation is generally rejected by the Chairman of the Japan Sumo Association. A tate-gyōji's submission of his resignation can usually be regarded as simply a gesture of apology from one of the highest-ranked referees for his mistake. There have, however, been rare cases where the resignation has been accepted, or where the gyōji concerned has been suspended from duty for a short period.

Ring Names[edit]

As with virtually all positions in the Sumo Association, including the wrestlers and the oyakata, the gyōji take on a professional name, which can change as he is promoted. All gyōji will have either the family name Kimura or Shikimori and will acquire a fairly old-fashioned personal name by the time they reach the senior levels. In addition the lower-ranked tate-gyōji is always named Shikimori Inosuke and the higher-ranked one Kimura Shōnosuke (It is traditional in Japan to give the family name first.) These two names are based on famous gyōji from the Edo Period.

The current highest-ranking gyoji is the 37th Kimura Shōnosuke and has held the position since 2013. His birth name is Saburō Hatakeyama, and he belongs to Tomozuna stable.
