Overview

  • The Nuclear Regulation Authority said the work-issued smartphone was used for emergency calls and texts and did not contain operational nuclear information.
  • Kyodo and the Asahi Shimbun reported the device stored names and contact details of staff in the agency’s nuclear security division, whose identities are kept confidential.
  • The phone is believed to have been lost during a security check at Shanghai airport on November 3, with the loss noticed three days later and no ability to remotely lock or wipe it.
  • The regulator reported the incident in November to Japan’s personal information oversight body, and there has been no confirmation of any data leak.
  • The case became public as the NRA evaluates TEPCO’s bid to restart the Kashiwazaki-Kariwa plant, drawing added attention given recent strains in China–Japan relations over Taiwan-related remarks by Prime Minister Sanae Takaichi.
