So when this tour was first mentioned, people were concerned about whether or not Ayu would be able to attend a-nation this year, but (I don't think this has been posted yet?) a-nation 2012 is very different this year. The "stadium" performances are only at Osaka and Tokyo, while "music week" is held in Shibuya from the 3rd of August until the 12th.
There hasn't been any artist lists yet, but I just wanted to say that assuming the tour doesn't get extended, there's still a chance Ayu could appear at the Osaka and Tokyo dates, which are the 18th and 19th (Osaka) and 25th and 26th (Chofu).
Didn't want to make a new thread just yet, since there's no artist list.
