Geeze, I had a horrible time at the Kodokan...
I showed up dressed in my gi and asked to be given a "VIP tour" and they basically blew me off.
Apparently it was "photo day" with the Japanese National team or something so a lot of Olympic & national champions, past & present, were there. Well, after being exceeding polite for a while, I became a little disappointed with the lack of aknowledgement, so I flipped over ONE bench in the lobby, as a protest.
Now they are asking me to leave --Show up, get treated like sh!t then get asked to leave! --The place was unbelieveable.
I stood in the center of the lobby --SILENT-- doing Shendokan Yogic Breathing exercises for a full 20 minutes, before leaving WITHOUT bowing --which is about THE most disrespectful thing you can do at a true Japanese dojo.
Hope they learned something that day.
