I could rattle on with band names and obscure Japanese releases until I'm blue in the face, but in lieu of this, here's something worth a listen.
The Hawks - Burai no hana
When I downloaded it, I needed to rename the extension to .mp3, so you may have to do that.
I really really love this track, "Burai no hana" from Osaka's The Hawks, known from a variety of streetpunk compilations such as the True Force Official Rules double 7", the Kick to be Alive 10", and the Burst Out! West Japanese Skinheads LP, among others.
Basically, think of an ultra-catchy slightly raw take on classic Cockney Rejects style streetpunk and you've got The Hawks.
Now who wants to start a Japanese crust/anarcho/grindcore thread besides me?
