BANZAI! The initial clash brings combatants flying toward a thunderous embrace. The object: Topple your opponent or knock him out of the dohyo, or ring. Each may grab and pull his opponent's mawashi belt, but not the strap girding the groin. Short but intense, most matches last less than a minute. The grandly attired gyoji is more than a referee; if wrestlers lock into weary stalemate, he barks encouragement.
