Venue Etiquette: What Not to Do
Nobody wants to be the visitor who gets told off. The good news is that sumo is not a minefield of unspoken rules — there are about five things worth knowing, and once you know them you can relax and watch.
Leave your trumpet at home
This is the one that catches people out, and it is worth saying first because it changes what the whole day sounds like.
You cannot bring instruments to support with. No trumpets, no drums, no whistles, nothing metal to bang. You cannot wave flags or banners that block the people behind you. And you cannot organise the crowd or lead it in a chant.
There is no supporters' section in a sumo hall. Nobody is conducting.
Shouting a wrestler's name is normal and welcome. Reacting loudly to a bout is what the building is for. What is not allowed is organised noise — a section chanting together, or anyone leading the crowd. React as much as you like; just react to the sumo.
Bottles and cans do not go in
Of everything on the prohibited list, this is the one an ordinary visitor actually runs into.
Bottles, cans and cool boxes are not allowed inside. Bags can be checked on the way in. So if you have picked up a drink on the way, plan for it not to come in as it is.
The rest of the list is what you would expect: nothing dangerous, nothing that smells strongly or makes a noise, no animals apart from guide and hearing dogs, and nothing brought along to hold more seats than you have paid for.
Four things a polite visitor still gets wrong
These are the ones you could break without meaning to.
Sitting in the wrong seat. Sit in the seat on your ticket. Do not settle in an empty better one, and do not watch from an aisle, a staircase or a doorway.
Using flash. Flash and light beams that get in the way of the view or the competition are not allowed. This is the easiest one to break with a phone in your hand.
Leaning out or climbing. Do not climb on railings, sit astride them or lean out past your seat. Do not throw anything towards the ring or the seating, and obviously do not get into the ring.
Making noise that is not about the sumo. Shouting for the sake of shouting, inside or outside the building, is on the list.
The trap for new viewers
Reading a list like this, it is easy to picture a stern, silent hall where you are afraid to move. It is not like that. A sumo crowd eats, drinks, talks between bouts and roars at the good ones. The rules are narrower than they look — they are mostly about not spoiling the view or the sound for the person next to you.
Keep half an eye out
One thing genuinely worth taking seriously.
There is no barrier around the ring. Wrestlers who lose sometimes leave it at speed, in whatever direction they were going, and the nearest seats — the 溜席 described in going to a basho — are on the floor at the edge of the clay.
The Association's spectator terms say this in as many words: watch out for wrestlers and referees falling, and for things flying into the seating, and take care not to get hurt. Nobody is going to stop it happening on your behalf.
If you are down at the front, keep looking at the ring. That is where it will come from.
When it ends, it ends
After the last bout you are expected to leave promptly, following the staff.
Since the biggest bout of the day is the last one — see why the best bouts come last — that means several thousand people head for the exit at the same time, straight after the thing they all stayed for. Worth knowing if you have a train to catch.
None of this is folklore we have collected. The Sumo Association publishes spectator terms that you agree to when you buy a ticket, and everything above is in them. If you would rather read the source than take our word for it, the link is at the foot of this page — and individual venues can add rules of their own on top.
What to watch for
Listen for the hall going quiet.
Because nobody leads the crowd, silence arrives the same way noise does — several thousand people falling quiet at the same moment, usually in the seconds before the charge. That is not politeness. It is a lot of people concentrating on the same small circle at once, and it is the thing a stream cannot give you.
Which tournament, which seat, and what time to arrive.
