So much formality and tradition in Sumo as in Japanese culture. Here the ref, dressed in a fancy red outfit
is facing to the East, away from the wrestlers. This means the wrestlers are just trying to stare down the other.
Soon the red-ref will turn and face them to show it is time to go. They have up to 4 minutes of stare downs.

Now a different ref is facing them and they are ready to go. They can charge when three fists touch the ground.
Refs change every 3-5 matches depending on the rank of who is matched with who. Or whom.

Closer shot of the fancy outfit of the Gyouji (ref).

This structure hangs above the sumo ring. At one time it was supported by four poles.

These flags are lowered when the house sells out.

The left side of the sumo stadium.

The (bazuke) list of who is against who and then who won. the red light above or below the name marks the winner.
The left one with a red light above and below shows the next/current match.

A huge 5 megapixel shot of the whole ring.

Another 5m shot of the upper ranks entrance ceremony.

So basically when the shots are small like this it means the shot is huge, like 5 megapixels.
This one is of a match.

The full house flags are dropped.

It's seen as a talent for a fat sumo wrestler to lift his leg straight up when he slams it down to
stomp out the demons. This guy got a big applause for his stretching.

We almost got the super box seats until someone said they were tight for Japanese people.
Which means absurdly too small for foreigners.

Sumo wrestlers throw salt to purify the ring before each match. The water bucket is for them to sip from.
It is also sacred.

The Yokozuna enters the ring wearing a big white rope and does several poses and a small dance.

He has an entourage.

I wouldn't really say "dance" he just shuffles around and does some mean looking poses.

All around the stadium are previous grand champions.
