The Yoko-gake (Side body drop) Waza consists of sweeping the weight supporting leg and sacrificing one's own posture while throwing the opponent. This Waza is often used from a Kenka yotsu (Asymmetrical grips by the two opponents) stance.
Tori (Player executing technique) advances to induce a counter advance by Uke (Player receiving opponent’s attack), and as Uke steps forward, Tori turns his back toward Uke as if to bring him onto Tori back, then he executes the Yoko-gake (Side body drop).
Tori does this while lifting Uke with his Tsurite (Lifting hand), and pulling him forward to his Hiki-te (Pulling hand) so that Uke body is snugly against his own. Tori uses his Hiki-te (Pulling hand) side leg to catch Uke Tsurite (Lifting hand) side leg. As if performing a soccer inside kick, Tori sweeps Uke leg from behind with his own body going into a side-sacrifice posture. Using his own body weight, Tori pulls Uke straight downward to the floor.
This Waza can be used when the opponent aggressively attacks, or after an opponent's attack has been induced, etc. It can be performed in various ways, and showcases the combatant's quickness and intuition.
