Hello! I'd really appreciate it if someone could explain the rules for buying tickets for a concert in Japan. I understand correctly that you have to have a Japanese number and address in order to enter the lottery to buy a ticket, isn't it? And I'm a bit confused when I read the information on the website, there are some front row tickets, friends tickets and some other categories of tickets? And is there any advantage to buying a ticket in pre-sale than buying it already during the general sale in January, apart from the fact that you just get your ticket earlier? My apologies for the many questions!
