* Summary:
This is another dynamic Ashi waza (Foot / leg techniques) that closely resembles the Osoto-gari (Large outer reap).

* Features of this Waza:
Like the Osoto-gari (Large outer reap), this Osoto-guruma (Large outer wheel) reaps both of the opponent's legs, throwing onto his back.

* Waza details:
In order to facilitate a forward pull, Tori (Player executing technique) Tsurite (Lifting hand) grasps Uke (Player receiving opponent's attack) collarbone area, and his Hiki-te (Pulling hand) grasps Uke (Player receiving opponent's attack) below the elbow.

Tori (Player executing technique) pulls Uke (Player receiving opponent's attack) forward on the Hiki-te (Pulling hand) side, and moves his body inward and advances his Support leg to Uke (Player receiving opponent's attack) Tsurite (Lifting hand) side.

At the same time, Tori (Player executing technique) bends the knee of his Tsurite (Lifting hand) side leg to prepare for wrapping it around behind Uke (Player receiving opponent's attack).

When Uke (Player receiving opponent's attack) is then destabilized toward the back, Tori (Player executing technique) extends his prepared leg behind Uke (Player receiving opponent's attack) (beneath his hips) and uses that leg as a fulcrum to throw Uke (Player receiving opponent's attack) in a rotational motion onto his back.

The throw is performed most efficiently with Tori (Player executing technique) Tsurite (Lifting hand) grasping Uke (Player receiving opponent's attack) collar, with the inner side of his elbow lifting Uke (Player receiving opponent's attack) jaw to force him back, and with his Hiki-te (Pulling hand) pulling Uke (Player receiving opponent's attack).

Because this Waza reaps both legs from behind, it is important to keep using the Hiki-te (Pulling hand) effectively even during the throw to prevent the opponent's head from striking the floor with too much force.

* Waza usage tip:
As a feint, an Osoto-gari (Large outer reap) with an insufficient pulling force can be used, with this Waza then being executed at the moment when the opponent shifts his weight to escape.
