It's interesting after reading an interview with Christian Tessier who said he basically debunks ki (on Aikido Journal??) and isn't Takeda Sensei his teacher???
Tissier wasn't Takeda's student. He was close to Yamaguchi, who was Takeda's teacher. But Yamaguchi never did this kind of demo. I've seen another video of Takeda in his own dojo in Kamakura where he does some more of the no touch waza.
The waza start at around the 5:20 mark.
