the only yoshikan instructor in the uk is sensei david rubins in london. as far as i know. I'm pretty sure he is. It's a shame eh?
Whoops. I was told last night by my JJ instructor that theres a few other oshikan instructors over here now. Not sure where they are tho.
There are Yoshinkan clubs in Hampshire, West Sussex, Hertfordshire, and Surrey as well. See www.kenshinkai.org.uk for more. Not really relevant to the original query tho', i'm afraid.
WWWWWWWRRRRONG! But you got told that then! For the best (but I would say that ) check out Ken Shin Kai
