the rum soaked fist: internal martial arts forum

I will be in Osaka from November 9th until, I'm hoping, the 16th. I'd like to experience some good Judo (or anything else that really stands out) while I'm there. Can anyone recommend some places to check out? Ideally, ones that will allow a non-Judoka/outsider to participate to some extent. My background is primarily CMA, with the emphasis being on Shuai Chiao for the past few years.

If there are any board members in that area, let me know if you have any time to have a drink and/or train.

Thanks in advance.
