^ Whoa...I think half of what you said got posted twice. ^^; It's alright, though.

I don't wanna say Ayu shows are never "sold out", because they've sold out before. (Such as in Hong Kong, Shanghai, and Taiwan.) You can always buy tickets online, and with the money you're spending, you should be able to get decent seats. (I've seen them sold at Yahoo Auctions Japan.) You could ask your friend to go to a reseller shop; they will most likely have tickets for the first shows. They should still have tickets when you get there, though, if that's what you do.

This concert may sell more than her other concerts. It is her 10th anniversary tour, so fans from throughout the years are more than likely going to go to her concerts. (Unless they absolutely hate her guts - than they probably won't go.)
