Japanese girl bands

How many japanese girls do you need to form a band?
Answer is 48!
That's right, that many. Japan has once again taken shyness to a new level! This group is called AKB48 (AKB=Akihabara) and they got 48 members. Well, okay, they have divided their members to three groups called Team A, K and B.

When I like to listen j-pop I prefer Hinoi-team because they make so stereotypical j-pop and I like it like that. They are also so damn funny. :D
