Maybe it defaults to that if you haven't put in another form of payment? I fake-started a checkout and went to change my payment method to see if it would come up. One option is

''Convenience store / ATM / Internet banking / e-Money payment You will be asked to pay before we ship your items. For items sold and shipped by Amazon.co.jp (including pre-orders), the Pay ID will be issued when we start shipping preparation. For items sold and shipped by Amazon Marketplace sellers, the Pay ID will be issued 30 minutes after the order is confirmed. Please read our click here page before you choose this payment method.''

The "click here" link gives basically a blank page, but checking Google it seems like that's an option that would either allow you to make a payment through certain convenience stores or with a Japanese bank account. I guess you take the pay ID to a participating store and are able to pay there through whatever method. I assume that's not an option, so maybe best to choose to cancel the item and try again, since the order page doesn't seem to have an option for changing payment method right there.
