Paul is right in that Kokikai is an orginization seperated from Tohei's Ki Aikido. They seem to follow the same ideas though.
Paul, I'd be curious as to hear more as to how you believe Tohei "watered down" his Aikido? Certainly he seems to have been one of Ueshiba's top students and teachers. By all accounts he was promoted to 10th dan by Ueshiba himself.http://www.aikidojournal.com/blog/2010/02/02/koichi-toheis-10th-dan-promotion-by-stanley-pranin/
I am starting another thread about all of this Paul, so PM or post there as this isn't really a thread for this sort of thing!
