Sumo is a traditional Japanese sport steeped in Shinto tradition. It is a form of wrestling where two opponents attempt to force each other out of a circular ring or into touching the ground with any part of their body other than the soles of their feet. SUMO has been practiced since ancient times and is considered a sacred ritual in Japan. The rules of the sport are based on Shinto beliefs, and the wrestlers often perform rituals before and after matches.
