Yobidashi are sumo’s ring attendants. They call each pair of wrestlers up with a long, fan-held chant, build and maintain the clay dohyo, sweep it between bouts, carry the sponsor banners around the ring, and beat the drum that signals the tournament. They are separate from the referee.
Caller, not referee. The yobidashi runs everything around and on the ring, while the gyoji is the referee who judges the bout inside the ring.
The signature chant. Before each bout, a yobidashi steps onto the ring with a folding fan and calls up the two wrestlers in a long, rising chant.
They build the ring. The dohyo is a hand-built clay platform that yobidashi construct, maintain, and sweep smooth between bouts.
Banners and drum. Yobidashi carry the kensho sponsor banners around the ring and beat the taiko drum that frames a sumo day.
A ranked career. Becoming a yobidashi is a long apprenticeship, rising through a ranked hierarchy with senior attendants handling the highest-profile bouts.
What is a yobidashi?
A yobidashi (呼出, “caller”) is a ring attendant in professional sumo. If you watch a tournament and wonder who chants the wrestlers’ names, sweeps the ring, and beats the drum you can hear across the arena, you are watching the yobidashi at work.
It helps to separate two roles that newcomers often blur together. The yobidashi runs everything around and on the ring. The gyoji is the referee who stands inside the ring and judges the bout itself. They wear different dress, train for different jobs, and answer to different parts of the sport. For the full picture of who calls the match, see our guide to the gyoji and shimpan.
What does a yobidashi do?
The yobidashi’s work is wider than most fans realize. The chant is just the part you hear most clearly.
Calling the wrestlers
This is the signature job and the source of the name. Before each bout, a yobidashi steps onto the ring holding a folding fan and calls up the two wrestlers, drawing out their names in a long, rising chant. The announcement tells the crowd who is about to fight and signals that the contest is near.
Building and tending the ring
The dohyo is not a permanent stage. It is a raised platform of packed clay that has to be built by hand for each tournament, kept in shape across the days of competition, and tidied constantly. Yobidashi are the ones who build it and maintain it. Between bouts they sweep and smooth the surface so each pair of wrestlers meets the same clean ring. To understand what they are shaping, read our guide to the dohyo.
Carrying the kensho banners
When a bout has sponsors, their advertising banners are paraded around the ring just before the wrestlers face off. Yobidashi carry those banners in a slow circuit, one flag per sponsor, so the crowd and the cameras see who is backing the match. The banners tie into the prize money a winner can collect; the mechanics are explained in our guide to kensho banners.
Beating the taiko drum
The deep drumbeat that frames a sumo day comes from a yobidashi. They beat the taiko (太鼓, a traditional drum) to mark the tournament, including the drumming that announces the coming day’s matches. The drum is part announcement, part atmosphere, and it carries far beyond the arena.
Yobidashi vs. gyoji: who does what
The two roles sit side by side throughout a honbasho, the official tournaments that decide the rankings. Keeping them straight makes the whole day easier to follow.
| Question | Yobidashi (ring attendant) | Gyoji (referee) |
|---|---|---|
| Where do they work? | Around and on the ring, between bouts | Inside the ring, during the bout |
| Main job | Call wrestlers up, build and sweep the ring, carry banners, beat the drum | Judge the bout and declare the winner |
| Tool in hand | Folding fan for the chant | Gunbai (war-fan) used to signal calls |
| Do they decide the result? | No | Yes, subject to the ringside judges |
A ranked career in traditional dress
Becoming a yobidashi is a long apprenticeship, not a part-time job. Like the gyoji, yobidashi advance through a ranked hierarchy over the course of a career, with the most senior attendants handling the highest-profile bouts. They appear on the ring in traditional dress, which is part of why the role reads as ceremonial even though the work is physical and constant.
The result is a profession that is easy to overlook and hard to do. The yobidashi keep the ring true, keep the schedule moving, and give each bout its opening chant and its closing sweep.
Frequently asked questions
What is the difference between a yobidashi and a gyoji?
The yobidashi is the ring attendant and the gyoji is the in-ring referee. Yobidashi call the wrestlers up, build and sweep the dohyo, carry the sponsor banners, and beat the drum. The gyoji stands inside the ring and judges the bout, declaring the winner.
What does the yobidashi chant before a bout?
The yobidashi calls up the two wrestlers due to fight, announcing the pairing in a long, drawn-out chant while holding a folding fan. The chant tells the crowd who is about to compete and signals that the bout is near.
Do yobidashi really build the sumo ring?
Yes. The dohyo is a hand-built clay ring that must be constructed and maintained for each tournament. Yobidashi build it, keep it in shape across the competition, and sweep and smooth it between bouts so every pair of wrestlers meets the same clean surface.
Why do yobidashi carry banners around the ring?
Those are kensho banners, the advertising flags of bouts that have sponsors. Yobidashi parade them around the ring just before the wrestlers face off so the crowd can see who is backing the match. The banners connect to the prize money the winner can collect.
What is the drum you hear at a sumo tournament?
It is the taiko, a traditional drum beaten by a yobidashi to mark the tournament. The drumming includes the beats that announce the coming day’s matches, and the sound carries well beyond the arena as part of the event’s atmosphere.
Is being a yobidashi a full-time profession?
Yes. Yobidashi follow a long career and rise through a ranked hierarchy, much like the gyoji. They train for the work, appear on the ring in traditional dress, and the most senior attendants handle the highest-profile bouts.
