I am trying to buy FC Tokyo tickets for 11.9 at Japan National Stadium - help!

The FC Tokyo site only sells home game tickets, and I csnt seem to register for J.League because I don’t have an address in Japan. Can anyone provide advice on what to do? I know the tickets themselves are not yet on sale, but I’d like to at least find a way to register on a site so I can purchase when they are available.

I tried to post in the JLeague subreddit but this question was too vague or something. Idk.

Thanks!
