Koshi guruma (hip wheel)

Summary

This Waza features a dynamic rotational throw over the hips.

Features of this Waza

In the Koshi-guruma (Hip wheel) Waza, Tori (Player executing technique) wraps an arm around the back of Uke (Player receiving opponent’s attack) neck and brings him onto the back of his hip, then spins like a wheel to throw him.

Waza details

In this Waza, Tori (Player executing technique) grasps Uke (Player receiving opponent’s attack) mid-sleeve area with his Hiki-te (Pulling hand), and the back of Uke (Player receiving opponent’s attack) collar with his Tsurite (Lifting hand).
Tori (Player executing technique) then uses his pulling hand to pull Uke (Player receiving opponent’s attack) forward, while shifting his lifting hand from the back of the collar to a posture in which his arm is around Uke (Player receiving opponent’s attack) neck
. When pulled forward by Tori (Player executing technique) pulling hand, Uke (Player receiving opponent’s attack) body moves toward Tori (Player executing technique) pulling hand side, thus inducing him to take a step forward.
At this point, Uke (Player receiving opponent’s attack) is in a sideways posture. As Tori (Player executing technique) wraps his arm around Uke (Player receiving opponent’s attack) neck, he quickly spins and places his hip against Uke (Player receiving opponent’s attack). Tori (Player executing technique) does this while also bending his knees and leaning his upper body forward, thereby further destabilizing Uke (Player receiving opponent’s attack) balance toward the front.
Pushing his hips deep so that they are crossways to Uke (Player receiving opponent’s attack) hips, Tori (Player executing technique) uses both the spring force generated by straightening his knees, and the force of his arm around Uke (Player receiving opponent’s attack) neck, to throw Uke (Player receiving opponent’s attack) over his hips and to the ground.

Waza usage tip

  • Tori (Player executing technique) must make effective use of his pulling hand, and when executing the throw, he must keep his side firmly closed.
  • Tori (Player executing technique) must release his arm from around Uke (Player receiving opponent’s attack) neck just before Uke (Player receiving opponent’s attack) hits the floor, and must gauge his pulling hand Zanshin (Awareness) (posture following the attack, in which the attacker remains watchful while reducing the force).
