It's interesting to note the list of "mysterious teachers" above (Sawada is the one from Nagoya, and there is some interesting back story there that I won't go into) - all of who are apparently acceptable to the conventional Aikido community even though they do mysterious things with little or no explanation.
I for one would be interested in the back story to Sawada. I gather he was a student of both Chiba and Watanabe. What do you mean by they are "apparently acceptable" to the conventional aikido community? What mysterious things? Are they relevant to the title of this thread that I inadvertently started?
