Nage Waza - Sumi Gaeshi

Sumi Gaeshi

Sumi Gaeshi, also known as the corner throw, is the first technique in the Dai Yonkyo from the Gokyo no Waza.  To execute Sumi Gaeshi:

1. Break uke's balance to his/her right front corner.
2. Fall back, placing your right foot instep in the crook of uke's left knee or on his/her left thigh.
3. Raise your leg while falling (not after you touch the mat) and throw uke over your head.
