I have to admit it's a little different when your teacher is Japanese. But even he has made adjustments for teaching in America, as opposed to Japan.
I also agree that there is a certain amount of 'dress up and play samurai' out there, and no, I don't particularly like that, although I'm probably guilty of a certain amount of it myself. But as time has gone by, I've mostly just decided to ignore that, and get on with training. I'm not too worried about teaching myself.
