Ayu is still promoting her "FIVE" album, which only got to be performed at a-nation, and so many people complained about (Japanese fans on twitter and Team Ayu blog, I mean). I can't blame her for wanting to promote her album, she may be Ayu but she still needs to move her merchandise like any other performer. Sales are part of what keeps her on top.
She can't exactly have an "Arena Tour 2011 ~FIVE~" kind of show, it wouldn't really work.
