If I understood correctly, Maaya will hold a couple of concerts at the Itsukushima shrine again this year! They say the live will only be about 1,5 hours long, I guess that's why two days? 7000 yen advance sale price for the tickets.
I'm planning to go. She will do the same performance both days. Yeah, it will last around 1 hour and a half because we need to take the last ferry to go back to the main island. (that's how it works there and that's how it was last year)
If there's a 2nd lottery round I can help. (I couldn't enter the first one but a friend entered for me)
