A member of the Japanese nuclear authority lost a phone with sensitive data, the incident occurring in the context of tensions with China and the resumption of nuclear activities in Japan.

An employee of the Nuclear Regulation Authority of Japan lost a work phone, likely at Shanghai airport, on November 3. The device contained a confidential list with the names and contact details of personnel from the nuclear security division, sensitive information that is not publicly accessible. The incident was reported to a Japanese data protection agency, and officials stated that the phone was not used to access nuclear data.

The loss of the phone occurs in a context of tensions between Japan and China, especially following comments by Japanese Prime Minister Sanae Takaichi regarding a possible military response in the event of an attack on Taiwan. Additionally, the Nuclear Regulation Authority is reviewing Tokyo Electric Power's (TEPCO) request to restart the Kashiwazaki-Kariwa nuclear power plant, in the context of Japan's return to nuclear energy after the Fukushima accident in 2011.
