I think an important distinction that is often lost is
a) taking ukemi as in recieving your teacher's technique (doesn't equate to falling, though you might)

Not sure about Kokyu, but I have been told by my previous Japanese teacher that it is customary in Japanese Dojos (especially in universities) not to allow the new comers to execute any techniques. They have to spend the first few months just taking Ukemi for senior students. Many Aikidoists believe that one learns best by taking Ukemi for notorious Shihans. I have no idea whether this really is the best way to learn, but I have heard it often enough to get the impression it is a wide spread belief.
