An employee of the Secretariat of Japan’s Nuclear Regulation Authority lost a workplace smartphone with highly classified personal information while on a private trip to China last year.

The Secretariat says the employee reported the loss on November 6.

The person was visiting Shanghai until November 3, and appears to have lost the phone during a security screening before flying back to Japan.

The smartphone contains the names and contacts of Secretariat employees involved with nuclear security, such as anti-terrorist measures at nuclear facilities.

There is currently no evidence to suggest any of the phone’s contents have been leaked, but the Secretariat reported the matter to the government’s Personal Information Protection Commission.

The Secretariat plans to take steps to prevent a recurrence, such as banning employees from carrying workplace smartphones when traveling abroad.
