MAN you people.
She can speak english.
If you look online or do research, MOST JAPANESE CAN SPEAK ENGLISH - maybe not PERFECT, FLUENT english, but english.

Her concerts are no proof. She uses a Japanese accent because she's talking to a JAPANESE crowd.

If most Japanese know ENGLISH, why wouldn't Japan's most famous/best selling artist not know english?!

Anyways...It says all the time - Ayu writes her own lyrics.
Verdict: then who the hell wrote Real Me?
Ayu maybe? Hm...let me think about it.

EDIT:..........errm..I seem to be in a mood today, scuse me.
Anyways, there's your point.
