Here in Canada, JPop/JRock is like... unknown. People that actually like listening to JPop and/or JRock habitually have a link to something else that is Japanese... What link is it, you say? Easy : animes. Even then, some people only stick to the songs they hear. So, what are the chances that someone hears B'z in an anime? Unless they watch Detective Conan, there is only a handful of anime in which B'z appears. Songs like Roots and Mienai Chikara ~Invisible One~ were in animes. Fortunately, Friction might have helped people discover B'z... or not. People playing the game Burnout Dominator or Burnout Paradise might like the song, so they head to buy Friction on iTunes... but when they inform themselves and find out that B'z is Japanese they might simply say "Eww...".
Anyway, most of the time, there are a couple of factors, imo, that doesn't help JPop at all :
- Inability for people to accept to listen to an asian language to be in a song. They all categorize it has "Chinese".
- Japanese labels refuses to market Jpop/Jrock/JTrance/Eurobeat/Trance/[...] outside of Japan. There are exceptions but a lot of those you will find in Canada and US are bootlegs.
- Non-openess of Japanese artist to tour outside of Japan. Except Visual Kei bands of course. There are a few exception to this... exemple : m.o.v.e. If there is a band or singer that tours outside, I'm pretty sure it's related to anime somehow.
Lastly, I think it's sad that only Visual Kei bands gets lights. I do have my explanation... Visual kei bands actually have sad lyrics and music (which is also aggressive; Visual Kei being a sub-genre of Metal). So, I kind of attribute to the "Why-does-this-happen-to-me syndrome" which seem to affect every country EXCEPT Japan.
Anyway, I'm out.
