My understanding of written and spoken Japanese lags behind my known vocabulary and grammar by quite a bit. I'm looking for places to find interesting Japanese media to help with immersion outside Japan. Music, games, podcasts, books.
Basically I'm looking for Japanese equivalents of where I go for English media. For example, how can I discover the Japanese Radiohead? Flaming Lips? Air? Justice? For English music I know I can surf the iTunes music store, Amazon, or eMusic, but where can I find Japanese music, and not just the stuff they assume Americans are interested in? What are they listening to over there?
Same for games, podcasts, books, ... Maybe I just need to go back to Japan, but so long as I'm stuck here, I'd like to know.
