Sumo is a competitive contact sport and the most suitable to fulfil the aim of enriching “Soul, Skill and Body”. A match ls played between two players, designated east and west. They make the best possible use of the 4.55 metre diameter dohyo and fight, almost naked, using their full strength to force their opponent out of the dohyo or to touch the ground with any part of the body other than the soles of the feet. A good sumo athlete respects their opponent, and whether victorious or defeated, they leave the dohyo with honour for a bout well played.
