I trained at Vasquez and Teshiba's dojo when they were based in Miami. He was rokudan and "Shihan." She was godan. They were both excellent instructors in my view, and I got a good vibe from the dojo. I think it's better than a Vegas or Altantic City slot odds to say that Pablo Vasquez is not Japanese. Before I went there long ago, I visited the website and was confused. I had though that each school had one Shihan, as the ASU does (unless Ikeda's label as "successor shihan" also means flat-out shihan). So, I was confused how Yamada Shihan shared that title of master instructor with advanced sensei in his own organization (USAF). Then there's the shidoin label, which I don't understand. Does someone?
