An unknown computer system problem continues to prevent the city of Osaka in western Japan from issuing official documents to residents.
The server that processes resident information developed the trouble on Friday afternoon.
Copies of residence registries, certificates of national health insurance and tax payments cannot be issued at the city's 24 ward offices, as well as municipal tax offices and service counters at railway stations.
City officials say they haven't identified the cause and that they were unable to process nearly 800 requests for documents.
They say people who have national ID cards can access some of the services at convenience stores.
Osaka Mayor Ichiro Matsui apologized for the trouble. He said city officials are working with engineers from the server's manufacturer to determine the cause and resume the services as soon as possible.
