Thank you for some pointers.
Jo awase, as he taught it, was a six count kata where both sides did the exact same movements (choku tsuki, mamote, men uchi, step back, gedan gaeshi, etc) simultaneously. It was an exercise in learning to blend with the partner's movement, picking up his energy and his "breath", while learning to move smoothly, solidly and with a stable center.
so...is it the same with this jo renzoku dosa
of y. kobayashi? and not this jo awase
of m. saito or maybe just a variation?
