Ayu definitely sells out wherever she goes! My friend tried to get tickets, but there's a lottery system and our number never came up before the tickets sold out for the Yoyogi shows in Tokyo.
The tickets are like 7800yen a piece which is really cheap looking at concert tickets in America! That's like $70. It's weird though because all the tickets are the same price in the arena! There's no different price levels for good or bad seats.
Madonna charges $350 face value for her best seats, and I think Ayu has the same sort of status in Japan, so she could really make a lot more money! It's nice that she doesn't gouge people with high prices, though
