well im actually wondering about japanese rap artists in general... all ive been exposed to are the teriyaki boyz so i was wondering what other japanese rap artists are popular

All I can think of is Orange Range. I think they are more like Linkin Park. don't know if you'll be interested.

Buddha Brand is all you need they are the definition of japanese hip-hop

m-flo&teriyaki boyz..thats ALL i can think of. hahahah

Suite chic (a bunch of artists including namie.. etc)

maybe king gidora(giddra?), s-word, sphere of influence, or zeebra. theyre more like rap though if it makes a difference..

Dragon Ash which is more of a Reggae sound..
Heartsdale
SoulHead
Bennie K
Suite Chic
Rip Slyme (which Ilmare + Ryo Z from Teriyaki Boyz are from)
m-Flo
Zeebra
and Teriyaki Boyz

i heard that song by teriyaki boys from tokyo drift... i dunno if i find that song reallllllllllllllly annoying or if i actually like it...

shing02 & nujabes (not really a group)..... yeah that's all i could think of.

sphere of influence, kamikaze grey
