Styles in Okinawan karate did not begin until after WWII, imitating the Japanese karate styles. Before that there were just instructors and they taught as they needed.
Isn't the date for styles emerging closer to the turn of the century (19th to 20th of course). Anko Itosu codified what he had learned, created the Pinan (Heian) Kata to make it more digestible, and that was transmitted to Gichin Funakoshi, who in turn transmitted it to Japan. In 1929 Chojun Miyagi took what he learned in China, what he learned from Higashionna, and named it Goju-Ryu.
It's true that the formal Japanese style of training and ranking didn't take hold until after WWII, which is why you get extremely fast rank progression among the original Marines. Prior to this, you had informal meetings in people's back yards. Each student was taught according to what their master wanted to concentrate on, and what he felt would best suit them.
@dancingalone: I'm not surprised that styles were codified, and it's not a bad thing, but we concentrate on it too much. We concentrate on what is "correct," but we forget that different people have different needs. Example from Isshinryu: Armstrong and his students, from what I've seen don't chamber their blocks. They come directly from the hip. For Armstrong, this was fine, he was a very large man. Someone smaller would probably have to use sabaki movements coupled with a parry to turn the "block" into a striking movement. Depends on your interpretation of something as simple as the basics. A problem occurs when there is a blind following and no understanding of what's being done. With the heavy Japanese influence post-WWII, I can see how this would happen with Okinawan Karate Kempo. Japanese society is conformist by nature. The old Japanese saying goes, "The nail that sticks out is hammered down." Anyone doing something radical would be considered wrong, and would be culled quickly. The Kempo jutsu in Okinawa would have to quickly conform to Japanese Karate-do if it wanted to survive.
@Mr. Mattocks: I've heard Mitchum's time spent in Okinawa happened over a 7 and a half year period. Originally, people said that he had trained in Okinawa for 7 and a half years, but his service record would show otherwise. He made 3 tours to Okinawa in that time, but I'm not sure what the actual total time training was. Many others went back as well, Advincula comes to mind, but I'm not sure what their ideas were about transmission. Strict transmission of source material is a very Japanese idea. As Mr. Smith pointed out, Shimabuku was Okinawan. He didn't write things down, he taught what he liked at the time, and let people run with it. I ran into an Isshinryu school, I want to say in Canada (I was very young), where they used the traditional corkscrew style punch. Were they wrong? Well, it depends on if Shimabuku was screwing around with it for a few weeks and someone picked it up 40 years ago. I think the whole idea of Isshinryu as a codified system was a concept brought about by the US Marines. It's great that they tried to create a standard, but they each did it on their own, in different places, with zero pier review. It would be interesting if you could get say every person who is presently an 8th, 9th, or 10th dan in the same room to truly codify the system, but because of politics and ego that situation would likely be :hb: at best.
