To me, there are three reasons:
- as you know, the music market in our countries, unlike in Japan, is sticken by Internet;
- Japanese majors think that J-music abroad is a niche market (and, still, I think it is);
- their Western counterparts maybe don't even know about Japanese artists and J-music fans, or don't think it's profitable enough.
Actually, even in Taiwan, Korea or China, J-music is distributed by local labels under license. I think that, as you think, SMEJ and other Japanese majors just don't want to bother with it.

Same for me. Although I'm sometimes tempted to join, I'm not on Twitter by now. I'm not really keen on using Twitter for this "project" (neither Facebook, even if I'm on, I know that many people aren't). Something else independant would be finer, I think. Still, if it comes to be on Twitter, then I'll join ^^
If you want a comparison, we can talk about Babymetal. AFAIK their works aren't licensed in Europe. Despite this, they made an European tour in London, Paris and Berlin last summer, with tickets sold around €30 in standard concert halls (~1 000 - 2 000 seats). It was such a success that they added a new date on next November in London. I really can't see why Kalafina, who's heavily promoted by anime (when Babymetal only relies on internet buzz) couldn't have such a tour.
