When you register your card, a small amount (such as 10 yen) may be deducted from your card balance to verify the "validity of the registered card".
Usually, the refund is processed immediately.
If not, please wait up to 60 days for the refund.
If you do not receive a refund, please contact your credit card company.
The refund will be credited back to your balance, and depending on your credit card company's specifications, it may appear on your statement.
Please note that the transaction itself will not be canceled.
