Ushiro Otoshi Ukemi
Ushiro Otoshi is a form of backward breakfall. It is important that uke's feet and head exchange positions. To do that, the legs have to be lifted up and the upper body has to go down. First contact with the ground is made with the hand or the lower arm. Proper body tension ist of prime importance in order to accelerate the center upwards. It may be helpful to look at your hand that is about to make contact with the ground. If you master this ukemi it becomes very soft and lithe. The french name for this ukemi is "feuille morte", which means withered leaf (dead leaf literally)
