Yonkyo and the Forearm of Pain
YONKYO: Fourth teaching. Refers to pressure applied on a nerve point in the lower forearm to bring the attacker into a pinning position.
Tonight we mainly worked on Kokyu Nage (Breath Throw) of which the number of actual techniques seem endless. However, for a short time we switched to YONKYO. Yonkyo is a really fascinating technique because while learning it you might say "Yes this could be effective". But once a master of the technique has applied Yonkyo to your forearm you know that somehow a dagger has mysteriously been inserted to the center of bone and you MUST drop to the floor.
All the talk of harmony, flow, blending...it all disappears. All that matters is that you go down. When learning we mostly approximate it and sometimes I suppose the situation will mean Yonkyo is less piercing. And I'm told the more often it is done to you the less fearsome it becomes to you.
But for me the memory of Sidney Sensei softly controlling my arm followed by the stab into the center of my forearm as I dropped, is a reminder of two things.
1. Aikido started as a way to effectively control and manage an attack
2. While techniques can be learned in a reasonable amount of time. A real master is just that. A master of techniques.
The above video demonstrates Yonkyo but watching is such a pale intimation of the real deal.
