THE FOLLOWING WAS COPIED FROM A THREAD REGARDING HAKKO-RYU JUJUTSU:
I'm sorry to tell you that "Mr. Yokota" is currently an unsubstantiated "urban legend." I was a student of Albert C. Church from 1970-73 and I know his story and claims. I'm also familiar with the person who continues to perpetrate the "myth."the only other person whom I have heard of who studied under Okuyama who came to any prominence was Mr. Yokota, who later founded DaiYoshinRyu Aikido
I have yet to find any resource in Japan that identifies -- or has even mentioned -- "Dai Yoshin Ryu jujutsu."
If you do have Japanese sources that mention Mr. Chijiro Yokota or Dai Yoshin Ryu, I would love to include them in my library. Japanese citations would help me to validate some earlier claims -- which I'd love to do since I have a very fond memory of Church sensei.
Regards,
Guy
