Hello,
I'm sorry for any misunderstanding.
I've checked and see that you've placed this order for Japan address.
As informed earlier, These item codes will only work on North American Square Enix accounts and will not work on accounts from a different region.
I'm sorry this code wasn't eligible for Japan region.
However, if you no longer need this item, please refuse the package and write back to us so that we'll help you further.
I'm so sorry, but we can't offer any additional insight or action on this matter.
We appreciate your business and hope to see you again soon.
Best regards,
