I have seen this technique from Shioda Gozo in YouTube
the technique is more or less in the middle of this video.
it is when the Uke push Nage(Shioda sensei), but as the Uke touches the Nage, the Nage push his body forward into the Uke without touching him with his hand, then the Uke fall back.
i have seen this technique from O'sensei videos as well but not from his other students(maybe not yet).Not even in our Dojo do i have seen this technique.
Do anyone knows the name of this technique,and how it is done??
I belive this is an irimi but i have never seen an Irimi that go strait head-on with the attacker.
thank you in advance.
