Sumo Wrestling

There are also a number of other rarely used rules that can be used to determine the winner. For example a wrestler using an illegal technique (or kinjite) automatically loses, as does one whose mawashi (or belt) becomes completely undone. A wrestler failing to turn up for his bout (including through a prior injury) also automatically loses (fusenpai). After the winner is declared, an off-stage gyōji (or referee) determines the kimarite (or winning technique) used in the bout, which is then announced to the audience.
Matches often last only a few seconds, as usually one wrestler is quickly ousted from the circle or thrown to the ground. However, they can occasionally last for several minutes. Each match is preceded by an elaborate ceremonial ritual. The wrestlers themselves are renowned for their great girth as body mass is often a winning factor in sumo, though with skill, smaller wrestlers can topple far larger opponents.
