I think Japan might actually be different in regards to music performances. I know folks from a few lesser-known punk bands, the kind that might get 50 or so folks at a typical club show on a good night in the US, that did tours in Japan. They described the same kind of reverence at their shows in Japan, and punk isn't exactly known for reverent crowds. This was 10 to 15 years back, so things may be different now?
