选手在对手之前触地或者比对手在轮次中触地次数多为输。选手之间纠缠经常持续几秒钟,有时会到一分钟或更长。每年日本会举办六场相扑比赛。每次15天。The basic rules of sumo are simple: the wrestler who first touches the ground with anything besides the soles of his feet, or who leaves the ring before his opponent, loses. Fights take place on an elevated ring, called a "dohyo", which is made of clay and covered in a layer of sand. The fights themselves usually last only a few seconds, or in rare cases, about a minute.
