It took me a bunch of times before I got it right. I kept getting an error message and then at one point I think I typed in the "sample name" (something like "TARO YAMADA") for my name somewhere and it worked.
Write down/save whatever fake Japanese phone number you use and then you can use that and/or the email address to log in from the app. The tickets are sent right to the app and then you just show them your phone when you enter the stadium.
