Japanese Idols?

I've known these two since they were 4. I wonder if they really will make the big time.

These are two of M's classmates, who attend the Hiroshima Actors School learning to sing dance and other skills to help them debut into the J Pop scene. One of the groups from their school who has made it big is Perfume, who recently had one of their songs used on the movie Cars 2.
Here's hoping that they remember their first fans when they make it huge!
Good luck girls!
