MTV Japan, and Japanese radio
 

when i was in japan, i listened to many things on the radio that were really good, some of them i had the chance to ask random people what the name of the song was, and some of them i couldnt. they were really really good too!! my question is if anyone knows where to get some sort of cd or weekly/monthly best in japan? thanks a lot!

Oricon has daily/weekly/monthly/yearly charts. They even have the weekly ones in romanized version.
It's really usefull to see what's currently hot in Japan. :P

Japan-A-Radio is a good internet radio station. They play a good bit of current stuff, but not a whole lot.

Thanks Peruvian Sky! This is awsome...
