In Japanese martial arts, Kaeshi Waza (返し技) refers to counter techniques where you reverse an opponent, often by turning their momentum against them to execute your own technique or to defend.   This advanced skill involves sensitivity to shifts in resistance, effective body movement (tai sabaki), and a deep understanding of timing to anticipate and exploit an opponent's mistakes.  There are several adaptable applications to this technique. Briefly, your initial throw is resisted and based on natural movement this is one possible adjustment to counter. In this example a gyaku waza technique is applied to finish by locking the elbow.    

     Sutemi basic meaning is to throw away your body or to sacrifice your body is ok too. Along with body, it is performed most efficiently mentally with complete fearless commitment. Another words total immersion and no holding back. The waza (technique) demonstrated is an adaptive flow and transition appropriate when the opponent resists in a particular manner. As with all techniques there are numerous details that need to be understood and applied skillfully to be successful.
