I've met Mr. Ochiai on many occasions and have competed with his son, Derek on the US Team. Mr. Ochiai was one of the few (then WUKO) Referees in the USA Referee Corps. From my experience, even if one makes up his karate frome whole cloth, in his garage- and I'm not saying he did- becoming a WUKO or WKF Referee requires such knowledge and training, that would make one "legit" and worth studying with. Also, I've known, made friends with, competed with and against so many of his current and former students, that I would say that any fears of walking into a McDojo should be dismissed out of hand. His students, and that's truly the measure of a teacher, isn't it- were top flight. They did extreemly well in kata, kumite, nationally and internationally. Having said that, my recollections of Mr. Ochiai's students was that they did shotokan kata and kihon in their kata performances, although Derek did a pretty good Seipai and Seienchin. Mr. Ochiai was the consummate gentleman. While I'm dubious of his published histories of his style, I wouldn't hesitate to send someone I cared about to train with Mr. Ochiai as he teaches the proper principles, from what I can see from observing and interacting with his students.
