Sumo is an ancient Japanese Shinto ritual or festival in which sumo wrestlers team up to fight in a ring , and is also one of the martial arts and martial arts that originated from it . Sumo wrestling is held as entertainment . It is internationally recognized as a martial art , martial art , and sport that originated in Japan .

Sumo is said to have originated before ancient times (traditionally, the age of myth ), and reached its peak as a form of entertainment for the common people during the Edo period [1]

Folklore research on modern sumo has looked at its leaders and historical lineage, from sumo sumo held by people who make a living doing sumo to sumo sumo amateur sumo such as student sumo and business group sumo , to local rituals and entertainment. It is divided into three types: sumo ( grass sumo, wild sumo, and dedication sumo, which were classified as ``amateur sumo'' by Ichiro Nitta, Masao Ikeda , and others) . [2] Sumo, a sporting event sponsored by the Japan Sumo Association, is particularly famous, but because it originates from a Shinto ritual, etiquette is more important than other professional sports, and the lifestyle and appearance are similar to traditional customs. There is also a cultural aspect, such as the fact that it is maintained.

It is sometimes said in the street that ``Japan's national sport is sumo,'' but Japan has not established a national sport by law or government ordinance .

Similar forms of martial arts in Japan and abroad include Okinawa sumo (shima) from the main island of Okinawa , buh from Mongolia , shuai jiao from China , sireum from the Korean peninsula , Yargureshi from Turkey , and rambu from Senegal . Each type of sumo has its own unique name, but when it is introduced in Japan, it is often referred to as so-and-so sumo (Okinawa sumo (Ryukaku Riki), Mongolian sumo, Turkish sumo, etc.).
