i wouldnt encourage you to buy from ebay though. reselling tickets should not be encouraged, and you can never tell if the ticket is authentic.

I guess they must exist, but I never heard of scams when it comes to buying Ayumi tickets through auction pages.

That's because the Japanese are ridiculously honest. For protection, though, you might want to stay away from "store" ticket auctions (yellow highlight on YJA). If it's just a little girl who can't go because her piano recital is on the same day -- you can probably trust her. ^_^ I've bought many tickets via eBay, and several items from YJA. I don't think there is any problem with the services.

Wait, Arena seats are obviously better than 200 level seats, right? Is there a seating chart somewhere to check where the seat is?

tommy, right you are. I assumed that 200-level seats were good for the price they were going... but they might have been close to the stage and level to Ayu (which would give you a not so good view of the overall concert, but a very close view of Ayu).

Here's a chart of Super Saitama Arena from an auction on Yahoo Auctions JP.

I've also seen diagrams where the numbers were reversed. x_x I'd personally get a 200 seat in the middle just in case. But I'm not getting a 200LV ticket.
