Kosoto-gake (Small outer hook or wrap) closely resembles the Kosoto-gari (Small outer reap). It consists of advancing toward the opponent, and then placing a foot behind the opponent to throw him down onto his back. This technique is classified as an Ashi waza (Foot / leg techniques). Its advance against the opponent is deeper when performing the throw and requires instantaneous leg and foot work.
Tori (Player executing technique) feigns an advance against
Uke (Player receiving opponent's attack), and then withdraws, pulling him
forward, waiting for the moment when Uke (Player receiving opponent's attack)
steps forward.
When Uke (Player receiving opponent's attack) pushes back
against the advance, Tori (Player executing technique) feigns a retreat, but
actually advances to hook the heel of Uke (Player receiving opponent's attack)
advancing foot.
Tori (Player executing technique) then pulls Uke (Player
receiving opponent's attack) in the direction of the hooked foot while also
grasping Uke (Player receiving opponent's attack) uniform between his shoulder
and chest with his Tsurite (Lifting hand), lifting Uke (Player receiving
opponent's attack) to destabilize and throw him.
In combination with both his arms, Tori (Player executing
technique) also wraps or hooks his forward-leg foot against the opponent’s
weight-supporting leg. Tori then drives with his own supporting leg to throw the
opponent backwards in a diagonal manner (toward 11 o’clock). Pictured is a low level Kosoto Gake.
