Almost there! After you choose credit card payment (THEY ONLY ACCEPT THE ABOVE CARDS LISTED – THEY ALSO DO NOT ACCEPT PAYPAL!) you fill in your details. It’s pretty straightforward from here, so after you’re done, click the 「次へ」grey button on the bottom right and it’ll take you to a page which confirms your credit card details. You can type the name on your card in English.
IMPORTANT! I get a lot of comments/emails from people who have the problem of Toranoana rejecting their debit Visa/Mastercard cards. I can confidently tell you that some debit cards work (mine works fine), but for others it doesn’t as it all depends on their card and bank. Japan usually doesn’t accept debit cards but if your card does not work, please check with your bank provider! I am not a banker, I cannot solve all your card problems.
After that, click the grey button on the bottom to confirm your whole order and you should be done! They will tell you that your order has been successful and the numbers you are given is your receipt and order number so keep that safe. You’ll also get an email that confirms your order and after that is the waiting game :)
