You might want to bounce over to e-budo's aiki-jujutsu forum (erroneously placed under the Kory section) and read some of the comments on the book there. There are some interesting comments being tossed out about some of those discussing the book, FWIW.
I think one thing worth noting is that the lack of any meaningful dialogue and the general level of understanding being displayed on the web from the martial artists reading the book -including those who translated it. Overal it does more to support Sagawa's view that almost no one "got it" than anything his detractors could offer.
At what point are bold statements...just the truth, and not arrogant, at all.
Thanks for the lead, Dan.
