A fundamental movement in daito ryu that I have experienced, this shows what is happening and that the holding the ball, pointing the thumbs and the footwork are all busywork designed to get a close approximation for the topple.
The waza shown by Okajima sensei is a 2 person pair movement starting from shizentai with only two steps. Think I'll have to film it..but then my poor technique is on show :(
