I would like to know more specifically how the deposit will be returned to me.

We will send a document asking for the return of the card and a bank account for the deposit refund upon cancellation of the card account. You will receive the deposit after we confirm the returned document and the card. Please be advised that, in principle, the deposit will be returned to a bank account in Japan. If you do not have a bank account in Japan, please consult with our customer service personnel.
