Japanese music/radio stations

Hello, do You know about any good online japanese radio station? It's easy to find a western station, with a specific genre, like metal or techno, but I coludn't find anything interesting with Japanese music. Only boring news stations, or pop-like music which I can't even describe :giveup: The only 'good' thing i found was a stream by, i think, a japanesee teenager, playing music from her PC? :D But the quality and volume was so bad...

Also, could You recommend some japanese bands/songs? I've dug through threads here, but most of them are about j-pop/rock.
What I'm looking for are bands with a female vocalist, with rock/punk/metal/techno(or any electronic) like music, alone or mixed with other genres. I don't mind, as long as it's not jazz or pop, or it's just a good song. I know about anime music, I love it, but I prefer to listen to it while watching openings/endings

I already know Maximum the Hormone, it's cool, even with male lead vocal :D. I found Rampant some time ago, but they're not popular, and have only few songs on their YT channel. Vocaloid is ok too, but I know only few songs with Miku, so feel free to recomend some.

Thanks!
