However, we have not been able to process
it, because we were not able to receive
authorization from the issuer of your card.

Before sending this email, we attempted manually
to receive authorization, but it seems that the
card you selected for your order is currently not
available for your order, because it was still
declined.

Please contact the issuer of your card to make
sure the card is valid for the amount of your
order ( 12100yen).

Sometimes, international transactions may be
blocked for security reasons.

When you contact them, please also ask to see if
this might be the case. CDJapan is an online
shop located in Tokyo, Japan (Company name:
Neo Wing Co).

After contacting them, and making sure your
card is valid for your order, please contact us,
and we'll try to process your order again.

In case you'd like to use another credit card,
please add it to your customer account first,
and then let us know.

*If you need to communicate to us which credit
card to use, please write only the last four
digits. For your security, please do not send
your full credit card information over e-mails.

In case we are not able to process your order
in the next 2 weeks, the order will have to be
cancelled.
