Please be assured that our system does not allow multiple credit card or Paypal debits (Paypal only accepts Japanese yen) for a single order.
However, we are sorry to say that our system is designed to check the validity of the selected payment method (authorization), and depending on the payment method, a "Usage Alert Email" will be sent at the time the authorization process is performed.
When multiple authorization processes are performed, it may appear that several Usage Alert e-mails are sent or that you are billed multiple times, but please be assured that you are not being billed (debited or charged) twice.
If you apply with a debit card, the amount debited from your bank account may be temporarily deducted from your card due to the nature of the card.
Once payment is completed, the amount deducted by the authorization process will be returned to your bank account. However, if the refund cannot be confirmed after 7 days, please contact our support.
