I know from talking to my instructor that if you dojo hopped, which was common in Okinawa for Americans, you were taught little more then moves. For those that were sincere and trained hard, more was given, but the language barrier was still a problem. "Do" the way, was the way I was taught. All of my certificates up to my last, reflects Okinawa GoJu-Ryu Katate-Do. If there is more to it then this, then it is news to me. In GoJu, the kata taught life preservation, this was the "Do", the way. "Jutsu" ??
