The video above is showing karate practice in Okinawa and not aikido. And while we don’t train in exactly this way the principle here is common to all martial arts, the ability to receive. In aikido the person receiving the technique or “uke” is not merely an opponent nor a passive practice dummy. As uke you train yourself to actively receive the technique without fear, without backing down and without allowing yourself to be harmed. “With uke, don’t just back down and take it,” the Sensei here points out, “but go forward and receive actively. The mindset of martial arts is to advance forward whilst receiving.”In aikido the mindset is the same whether you are receiving an attack or receiving a technique. The ability to uke well is essential to good aikido practice.
