About the credit card payment errors

We have been receiving reports from overseas participants that they are unable to make card payments during registration. As a result of our investigation, it seems that the security of the credit card company is working to block the payment rather than a problem with the registration system itself.
We apologize for the inconvenience, but please try several types of cards or explain the situation to your credit card company and ask them to temporarily lower the security level.
