The nationwide online network for "shinkin" credit, savings and loans banks resumed normal operations at 8 a.m. Thursday after a computer problem that crippled the system the previous day was fixed, a shinkin bank information center said.
Automated teller machines and all other related services have been restored, the center said.
The center discovered that a malfunction of memory devices in the host and backup computers had caused the trouble, and not problems with host-computer operating software as initially thought.
