At Japan we lose many detail of traditional Jiujitsu because of Judo's strict policy.But that make certain part of BJJ and Judo fusion which not happen at otehr coutries.
I have made a list of Japanese BJJ Dojo & Gym with their official websites. There are loads of gyms, so I can’t introduce them all. Also many MMA gyms have BJJ classes which I don't introduces here. I’ll try to give the links to their website, what prefecture they are in, and what railway station is nearest (in that order). Sometimes when that information is not available, I’ll make a guess - I could be wrong.
