The Obi-otoshi (Belt drop) Waza consists of grasping the opponent's Belt, and then extending one's foot as a fulcrum over which to throw the opponent backwards to the floor.

Waza details

With his Hiki-te (Pulling hand), Tori (Player executing technique) grasps Uke (Player receiving opponent's attack) Belt from below. Then, while pulling him forward, Tori (Player executing technique) extends a leg behind Uke (Player receiving opponent's attack).
Tori (Player executing technique) bends the knee of the extended foot to lower his Center of gravity, making it easier to destabilize Uke (Player receiving opponent's attack) in the backward direction.
At this time, Tori (Player executing technique) releases his Hiki-te (Pulling hand) from Uke (Player receiving opponent's attack) Belt, and inserts that arm beneath Uke (Player receiving opponent's attack) armpit to lift Uke (Player receiving opponent's attack) chest area, while simultaneously performing a foot sweep to send Uke (Player receiving opponent's attack) falling on his back to the floor.
In order to maintain good balance and make the most efficient use of his force, Tori (Player executing technique) must grasp the nearest part of Uke (Player receiving opponent's attack) Belt front, and must pull Uke (Player receiving opponent's attack) firmly toward himself so that his body is snugly against Uke (Player receiving opponent's attack).
The fulcrum leg and the Tsurite (Lifting hand) then work in tandem to throw Uke (Player receiving opponent's attack) down in a rotational motion.
