While doing some research, I found this article... http://www.ryukyueastasianmartialarts.com/article2.html More from the article... Who were these two men? What is their story? Who did they learn te from? What is the connection with Shorin Ryu since Oyata's method uses Shorin kata? Does the story presented sound legitimate? Are there any additional sources that people can find to support it? Lots of questions, but very important because the 12 kata of Ryu Te are the most commonly practiced kata by karateka. If you've ever seen Oyata Sensei (or his students) move you know he's got some real knowledge. Lets did into it!
