I like to listen Japanese pop music and watch Japanese movie.
But I just know few stars.Can you recommand me?
What about MIKU..Uh-Huh!
I recommend BUMP OF CHICKEN, their songs are so touchy, but sometime quite rock
For Rock I would definitely suggest Miyavi, amazingly talented!! https://www.youtube.com/watch?v=wjQW_c-PyAk
I recently watched "Densha Otoko" and it was very cute! It is a romantic comedy. I also recommend "Summer Wars" and any Studio Ghibli movie.
For music, I like Asian Kung-Fu Generation (rock) and Kyary Pamyu Pamyu (pop).
