Hi tedehara!
A new technique? Don't know... if I kick to the face of my opponent before do a kote gaeshi, is it a new technique? Perhaps it's taken from taekwondo, so it's not BRANDnew...or?
O-sensei said, at first there are 16 techniques, and each one has 3000 variations. And in any situation you (can) create new ones. Good luck
Greetings
