Don't think anyone listens to jpop here, except for Chan maybe.
Only Jp music I listen to is like jrock pop, a little bit of techno influence, but not like Perfume which sings to techno beats more or less.
Polysics is pretty fun.
A lot of their stuff is hardly rock, but it's not near as poppy as perfume.
or Supercar
They got into a bit of electronic, but most of the songs on youtube are band instrument produced sound. (Sorry I guess I am getting electronic and techno mixed up lol)
Okay and I guess Haku_Honjo is a japanophile, apparently.
