Description of Tani otoshi
To perform the throw correctly the user of the technique takes a few steps backwards- after which he takes a step forward to the side of the opponent (right leg moves to the opponent's right and vice versa).
Next- the user turns to the opponent (while keeping the stepping leg in its place), drops to the floor, places his leg behind the opponent's ankles (the closer the leg is to the opponent's ankles- the better) and pull him backwards and downwards. The user's leg becomes an obstacle on which the opponent trips over.
