I recently saw the article https://tokyocheapo.com/events/summer-sonic/ and I really want to go to the Sonic Mania. My favorite band plays and I’ll be in Tokyo that week. So, I HAVE to go!
But I don’t know how to buy the ticket and if I’ll be available to buy it from outside Japan.
Last year there was at least one option for buying tickets from overseas. It doesn’t seem that there are any on sale yet for 2018, but keep an eye on this article, we’ll update it when we have further info.
