Japanese ticketing systems really are crazy. There's so many places you can buy tickets from and they don't even necessarily line up with each other (like tickets could be sold out at Lawsons but still around at the box office).

If I can get a ticket, there will definitey be an after report. I'm going to try my best to go. (It may, however, involve staying out all night in Kanagawa. I'm hoping this Ticket Pia thing works -_-;).
