Ashi waza (Foot / leg techniques)
Ashi waza (Foot / leg techniques) are part of the Nage waza (Throwing techniques) category, and consist of using one's foot / leg for reaping, tripping, sweeping, supporting, entangling, etc. A contestant applies these Waza by adding his own force to the opponent's motion in order to destabilize the opponent's Center of gravity in the forward, backward, or lateral direction, and then using his foot / leg to attack the opponent's leg and topple him. The Waza elements include reaping the opponent's leg to topple him, tripping him to further destabilize him, sweeping his leg to throw him, using one's own leg as a pivot from which to throw him, and entangling his leg in order to throw him in single sudden motion, etc. The Ashi waza (Foot / leg techniques) include the Uchi-mata (Inner-thigh reaping throw), the Osoto-gari (Large outer reap), the Sasae-tsurikomi-ashi (Supporting foot lift-pull throw), the Ouchi-gari (Large inner reap), the Kouchi-gari (Small inner reap), and the De-ashi-barai (-harai) (Forward foot sweep), etc.
