MetLife Insurance KK is investigating a suspected case of unauthorised data transfer involving one of its employees, raising concerns over information security in Japan’s life insurance sector.
The employee, who had been temporarily assigned to another organisation, is believed to have accessed and taken company-related information without approval. Early estimates suggest that several thousand data records may have been affected, potentially making it one of the largest such incidents in the country’s insurance industry.
The company has launched an internal probe and is expected to disclose detailed findings once the investigation is complete. Key areas of focus include whether the act was carried out independently or involved a broader network, and whether any personal or sensitive customer data was compromised.
The case comes amid a wider pattern emerging across the sector. Major insurers in Japan have reported similar incidents involving employees seconded to partner firms such as banks or sales agencies. For instance, Nippon Life Insurance previously identified over 1,500 instances of comparable data-handling issues, while Dai-ichi Life Holdings disclosed more than 1,100 cases earlier this year.
The incident underscores growing risks linked to employee mobility and third-party collaborations, especially in sectors handling sensitive financial and personal information. It also raises questions about the effectiveness of current safeguards as insurers increasingly rely on extended networks for distribution and operations.
