Well, the problem here is not just the Kojiki, but the fact that the Omoto-kyo interpretation of the Kojiki is somewhat different than the standard - and that Ueshiba's interpretation is often different from that.
What I was interested in was whether or not Kono had any specific comments on the differences, or whether that's your own personal assumption.
I spent a lot of time in Japan, and I saw just about everybody (including Hikitsuchi), and I'll have to disagree there, but I suppose that YMMV.
I may miscomprehend you here entirely, but are you saying that you saw just about all Aikido teachers in Japan and none of them practiced Aikido?
If so, how did you come to that conclusion?
