I saw several post on reddit about the difficulty of getting a credit card info through the registration of the app. I had a similar problem but managed to get it to work with a mastercard of one of my friend.
However, I saw that I might need the credit card in Japan to confirm my info and get my ticket, even if I buy them in advance. So my question is can I change my credit card info on my account or do I need to create another account and try with one of my card?
