I replied to PM, but I thought I should write here, in case anyone would like the info:
They asked me what day I want to reserve Miyako Odori, then woman told me what hours shows are held, I picked one, then she told me about 3 types of tickets, I picked one (basically you can see the info on their official website). Then she asked me for my name and nationality, then email. They said that I should pay full price for tickets on the day of the show at the theater. No bank transfers.
PS. They will send email confirmation, with whitch you should come to the theater.
