Can I change my payment method after placing an order?
Answer
You cannot change your payment method after an order is confirmed. However, you can cancel the order and place a new one with a different payment method.

Payment methods cannot be changed after an order is confirmed. If you wish to use a different payment method, you may cancel the order (before 9:30 a.m. Japan time and before shipping preparation begins) and place a new order using your preferred payment method.
