The normal selling price for Ayu concert ticket is 7800 Yen if I am right.
But you must be really lucky in the lotterys to get a good ticket for that price.
When you buy good seats in resller shops or on auction they can go up pretty high, but if you don´t care about were you sit you can get really bad seats on the date of the concert from reseller shops under original price.
