Sumo (相撲 sumō^?) or sumo wrestling is a competitive full-contact wrestling sport where a rikishi (wrestler) attempts to force another wrestler out of a circular ring (dohyō) or into touching the ground with anything other than the soles of his feet. The characters 相撲 literally mean "striking one another".

The sport originated in Japan, the only country where it is practiced professionally. It is generally considered a gendai budō (a modern Japanese martial art)

A 20 x 20 rectangular fighting ring features a flat bottom non-inflated floor with inflated walls to contain the wrestlers. It can be rented separately for a discounted price of $100 when renting sumo suits. The ring is listed as The Foam Pit in our list of attractions. @ additional suits can be rented for $25 each. In that way, you can have one team ready to wrestle immediately after a match so you don't have to wait for wrestlers to get out of their suits and new wrestlers to get in.

The images shown are to demonstrate the suits and not the actual ring which is more elaborate and resembles the ring in picture number 1. Also please note that the ring is inflated but the suits are padded and not inflated. 

The additional optional suits are manufactured by a different company and have different characteristics. While all suits meet industry standards, some are padded more than others, with the suits with thinner padding designed for warmer climates than the suits with heavier padding.
