The expiration date of the credit card is automatically updated due to a system called "Araigae" (roughly translated to "Reverse Check") provided in partnership between Japanese credit card issuers and payment processing companies.
"Araigae" is a service that confirms the validity of a card by checking the expiration date of the credit card, and automatically updates the card information if it has expired.
"Araigae" is particularly used by businesses offering subscription services to enhance user convenience.
*Araigae ensures no unauthorized payments occur without user consent.
*Due to system limitations, some cards may not support Araigae.
