Sumo wrestling is the fighting of huge males which have pounds of bulk in their body.

The sumo fighter mostly takes weight increasing drugs which are very harmful and this is the reason why the sumo wrestlers cannot live for long.

There are two principal ways to win a Sumo bout: First, is to make any part of the opponents body to touch the ground, other than the soles of his feet.

Secondly, by forcing the opponent to cross the rings circle boundary.

On rare occasions the referee or judges can determine that the wrestler touching first wins as the other wrestler was in an irrecoverable position (so called "dead body" or shiny-tai).

There are also a number of rarer methods, for example a wrestler using an illegal technique (or kainite) automatically loses, as does one whose awash becomes completely undone.

A wrestler failing to turn up for his bout (including through a prior injury) also automatically loses (fusenhai).
