Japan's health ministry is trying to repair a glitch in the nation's coronavirus contact-tracing app, which was rolled out just days ago.

The smartphone app is designed to notify users who are thought to have been in close contact with someone infected with the virus.

Japan's labor ministry is tackling a second data leak from an online system for businesses applying for coronavirus subsidies.

The system was launched on May 20 but was suspended hours later after officials learned that the personal details of applicants were exposed.
