Oshidashi: Frontal Push Out
Oshidashi (押し出し) is one of sumo's two most common winning techniques, together with yorikiri (in recent tournaments each decides about one in four sekitori bouts; see the kimarite board for current counts), and the defining move of oshi-zumo (pushing sumo) specialists. Rather than grabbing the belt, the attacker keeps his arms extended and drives the opponent out of the ring through sustained forward pressure on the torso or upper arms.
Oshi wrestlers typically have powerful arms, broad chests, and explosive thrusts called tsuppari (slapping pushes). Because they avoid belt grips, they can be vulnerable to pull-down moves when the momentum is reversed.
An oshidashi is recorded only when the attacker does not maintain a belt grip. If the same forward drive is completed while holding the mawashi, the result is usually yorikiri. That distinction makes the official result useful when comparing pushing specialists with belt wrestlers.
