Sumo

is a Japanese full-contact sport.Nussbaum, Louis-Frédéric. (2005). "Sumo" in Japan Encyclopedia, p. 914.

In sumo, a wrestler (rikishi) attempts to force another wrestler out of a circular ring (the dohyō) 4.55 metres in diameter. Also, the rikishi try to use their skill to force an opponent to touch the ground with anything other than the soles of his feet.

Sumo tournaments (basho) take place in Tokyo, Osaka, Nagoya and Fukuoka. There are a total of 6 major professional tournaments (known as honbasho) per year, in January, March, May, July, September and November.

A tournament normally lasts for 15 days and features matches from different divisions. The top 5 ranks are known as the "Top division", also called the Makuuchi (幕内) or Makunouchi (幕の内). It is fixed in size and always contains 42 rikishi.

The ranks included in the top division are yokozuna, ozeki, sekiwake, komusubi and maegashira.

Rikishi
Sumo wrestlers (rikishi) are ranked into a hierarchy based on win-loss statistics in competitive tournaments.Nussbaum, "Sumotori" in Japan Encyclopedia, pp. 914-915.

Foreign-born competitors
Sumo has changed in modern times. Foreign-born wrestlers are part of the sport. For example, KonishikiSumo Reference, Konishiki Yasokichi ; retrieved 2012-2-27. and AkebonoJapan Sumo Association, "Akebono" ; retrieved 2012-2-27. are Hawaiian-born athletes who earned places for themselves.

In 2008, Kotooshu from Bulgaria won a championship. In that same year, two top wrestlers, Asashoryu and Hakuho, were Mongolian. Hakuho won the Nagoya tournament with no losses, 15-0.
