It's taken a while, but punk rock seems to have finally broken into the J-pop mainstream.
Punk bands that have recently made it into the Oricon album chart include Nicotine, the Stance Punks, Sobut (whose name, by the way, stands for "Sons of Bitches United and True") and, of course, Mongol 800, whose album "Message" has sold more than 2 million copies since being released by Okinawan indie label Highwave last September.
Oricon's indies album chart, meanwhile, is overwhelmingly dominated by punk.
