Features of this Waza

Waza details

The Kataha-jime (Single-wing strangle) Waza takes its name from the appearance of Uke (Player receiving opponent's attack) trapped arm which looks like a single raised wing.
Tori (Player executing technique) wraps an arm around Uke (Player receiving opponent's attack) neck from behind, and grasps Uke (Player receiving opponent's attack) collar on the opposite side. In order to strengthen the strangle hold, Tori (Player executing technique) runs his other arm beneath Uke (Player receiving opponent's attack) armpit to scoop up his arm, and then behind Uke (Player receiving opponent's attack) head to clasp his other arm which is around Uke (Player receiving opponent's attack) neck. Tori (Player executing technique) can then tighten the strangle hold by using his behind-the-head arm to pull on his around-the-neck arm.
Tori (Player executing technique) can also use the forearm of his behind-the-head arm to push Uke (Player receiving opponent's attack) head forward to apply additional pressure. Even if Uke (Player receiving opponent's attack) is destabilized and topples to one side, Tori (Player executing technique) can maintain the efficacy of this strangle hold by using both legs to hold Uke (Player receiving opponent's attack) snugly against him. This Waza deprives Uke (Player receiving opponent's attack) of one arm and applies a powerful pressure to his windpipe. Uke (Player receiving opponent's attack) may attempt to escape by pulling his arm down to trap Tori (Player executing technique) arm in his armpit, but Tori (Player executing technique) can repel this by planting both feet firmly on the floor and bending his head back to apply more pressure.
Uke (Player receiving opponent's attack) may also attempt to escape from beneath Tori (Player executing technique) armpit by pulling on Tori (Player executing technique) sleeves with both his raised hand and his other hand.
