What exactly happened on January 29?

A systems failure at the national credit union center paused interbank transfers and some counter services across 140 credit unions. Most ATMs stayed available. Operations were restored the same afternoon, around 3:00 p.m. JST, with transactions resuming normal processing after recovery.

Were customer funds at risk during the outage?

There is no indication that balances were compromised. The impact centered on delayed transfers and paused counter services. Once systems came back online, queued transactions could process. If you see an unexpected delay, contact your credit union with reference numbers for tracing.

How can households and SMEs prepare for future disruptions?

Keep a secondary account for urgent payments, maintain a small cash buffer, and schedule key transfers a day earlier. Turn on service alerts and bookmark status pages. If disruption occurs, queue transactions, use card payments where possible, and confirm cutoffs to avoid overnight delays.

Will regulators investigate the outage?

Large, multi-institution incidents usually trigger reviews. Authorities may request a timeline, root cause, and recovery evidence, plus updates to contingency plans and notifications. Vendors and operators may need to show successful failover tests and capacity plans to reduce future disruption risks.
