Quick answer
Japan's July 16 credit card outage was caused by a failure in the international payment network, not individual bank infrastructures.
On July 16, Japan experienced a major credit card outage affecting thousands of retail outlets and transport companies nationwide. Card payments became impossible from early morning, creating chaos in major cities, including Tokyo.
Mitsui Sumitomo Card, one of the country's leading card issuers, issued an official statement explaining the incident. According to the company, the problem stemmed from a failure in the international payment network, not in individual bank or processing center services. This means the outage impacted not only Mitsui Sumitomo cards but also products from other issuers.
System restoration took several hours. By noon, payments resumed, though many stores and transport companies had already switched to alternative payment methods. In Tokyo stores, customers were advised to use cash or transit cards like Suica and Pasmo.
Experts note that such outages highlight the vulnerability of centralized payment systems. With growing reliance on cashless transactions, even brief technical issues can paralyze entire industries.
