Fast-food giant McDonald's Japan says some of its restaurants have suspended operations after their cash registers developed a glitch.
The chain operator says the trouble occurred on Friday. About 30 percent of its over 2,900 outlets across the country are affected.
A sign at a restaurant in Tokyo's Meguro Ward told customers it was closed.
McDonald's Japan says it is working to identify the cause.
The firm experienced a system failure in March, forcing many of its restaurants to suspend operations. It says that was triggered by a third-party provider during a configuration change.
McDonald's Japan has issued an apology. It says it will continue working to pinpoint the cause and resume operations as soon as possible.
