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.
Best,
Ron
