Sumo was known as Sumai in the 8th century. Back then the rules involved were less in number and men used to fight till death. That is the reason why the wrestler who looses in a match is referred to as Shini-tai or dead body. Even today some of the shrines conduct ritual dance where a man wrestles with a Kami or a Shinto deity. This contest was known as Sumai no Sechie or Sumai party. This ritual was also held in the imperial court and it was a must for the representatives of every province to attend this ceremony. Sumo was also a part of the training for the warriors and that’s the reason that originally sumo wrestlers were samurai.

This martial art originated in Japan centuries ago and has a great religious importance in the country. It has some traditional rituals involved such as meditation where the wrestler cannot sleep, which is part of the Shinto religion. Sumo wrestling of Japan even has influence on martial arts of its neighboring countries like Korean Ssireum, Chinese Shuai jiao, and Mongolian wrestling.
