Japanese Rock Sucks!
they only imitate english-spoken countries rock
if you go to japan you can see many "visual rock band" which are just imitate pre-David Bowie/or early Iggy Pop
And you can not tell their gender from their look
it makes me sick

you've been there?

Maybe he's big in Japan...

Wow, this is an informed opinion. If all you're listening to is J-Pop, you might be right, but a huge chunk of the most innovative and dynamic rock-oriented music in the world has been coming out of Japan for the past 2 decades.

Some of these have been mentioned, but I'll reiterate:

Ruins
Fushitsusha
Melt-Banana
Happy Family
Cornelius
Boredoms
OOIOO
Zeni Geva
Ground Zero
Acid Mothers Temple
Altered States
Bondage Fruit

you like Ruins?

oh and Tujiko Noriko is very good too, not really rock though, more altsamplepop or something like that

That's great because I know the inside joke! Wow, that's an old one, too...
