O-SOTO-OTOSHI

Key technical points:
1. to push Uke backwards, or use Uke's
pulling action;
2. to step behind Uke's leg and plant Tori's foot on the mat, so that Tori has complete control over the final phase of the throw and the falling direction of Uke;
3. to drive Uke to the mat safely and effectively allowing him to apply a
breakfall (Ushiro-Ukemi) cleanly.
