I was wondering if someone knows some good japanese radio streams?

I'm looking for pop/rock radios and also radios that play the current top songs in japan. I mean the new singles/oricon songs that are popular in japan.

I made a google search some time ago but there are so many that I have no idea if it's a big radio from Tokyo or a small amateur radio... I found some but it's mostly animes and old songs from a few years back it seems.

I thought I ask here maybe someone knows some good streams.

I go to this website http://www.shoutcast.com/radio/Japanese

Yeah thanks but i found it too during my research =D Was looking for a more precise answer so I wouldn't have to try all the radios .upwalk.

Maybe http://www.live365.com/stations/rec4?play ["[…] plays today's hottest hits from Japan including the weekly J1 Top-40 chart […]", needs a free account] could fit your needs?

Or maybe this: http://www.multilingualbooks.com/online-radio-japanese.html
Or this: http://www.simulradio.jp/

Or even… Jeez! There are hundreds =_=
And a few more: http://tunein.com/radio/Tokyo-r100932/
