1. Click here
2. To sign up as new member, click 新規申込
(first yellow button)
3. membership terms are shown. Click 同意する
to agree and continue.
4. fill in the form. some hints:
a) if there is (全角) after the field, it has to be filled in using full-width symbols, even for Latin letters. In Windows, you can do it by entering text with the IME on, then pressing F9.
b) fields marked (半角) only accept half-with (normal) letters or digits.
c) zip code should be three, then four digits. If yours is shorter, pad it with zeros. If longer, or includes digits, enter anything, then put the real zip code in the address lines.
NB: last four digits in the zip code will be a password for ticket ordering.
d) address lines accept only full-width symbols and no spaces. You can still use full-width underscores and commas. You might have to move words between lines to make it fit. I put country in the beginning of the address, but it might be a good idea to add it at the end too.
e) phone has to be 2-4-4 digits
f) it's better to fill in the real birth date (at least month/date), it will be your password.
I've attached commented screens of the form.
5. Click 確認する to continue. If you get an error, check the mentioned field name. E.g.
(you've entered incorrect "name". please use full-width symbols only)
Make sure to reenter the email address and credit-card info.
6. You will get a confirmation screen with the details you entered. Click 次へ to continue or 修正 to go back and fix.
7. next you'll get the payment confirmation screen. Click 決済する to pay or 手続中止 to cancel. If it goes well, you'll get the success screen.
