Panel backs Japan police phone hacking to fight fraud, but rights concerns remain

On September 2, Japan's National Police Agency (NPA) expert panel recommended early implementation of remote analysis of smartphones for use against anonymous, transient crime syndicates. This proposal stems from a sense of urgency, as conventional investigative methods struggle to prevent the escalating harm caused by increasingly severe crimes.

The proposed technique is expected to address the secrecy of communications, which is protected by the Constitution, raising questions about appropriate usage. According to the NPA, losses from special fraud cases committed through digital or telecommunications, including social media-based investment and romance scams, reached a record ¥325.7 billion (approximately $203.67 million) in 2025.

In the first half of 2026 alone, these losses were about 1.5 times the level from the same period a year prior. The panel's primary concern is the anonymity these crime groups employ, often using social media apps to find and hire individuals for these illicit activities – known as "dark part-time jobs" or "dark gigs" – all conducted anonymously.

To overcome this issue, the panel suggested remote analysis, a method that would enable police to identify and analyze the smartphones of those coordinating criminal activities based on reports from victims, statements from arrested suspects, and information from individuals seeking to leave these groups. Investigators could also apply under false identities, similar to a method introduced in 2025, to gather leads.

Remote analysis would function similarly to active cyber defense, where police and the Self-Defense Forces would legally access harmful servers to neutralize threats. The police would then search for crucial information left on the smartphones of coordinators, such as the names, addresses, roles, meeting places, and contact details of potential victims, roles, and bank accounts utilized in scams.

The goal is to prevent new cases of fraud and robbery. However, obtaining communications content raises constitutional concerns, as it may conflict with the secrecy of communications. The panel addressed this by proposing that remote analysis should be conducted under the condition of a warrant and subject to judicial review. The information obtained through remote analysis under administrative investigative authority is expected to be used not only for preventing harm but also in later criminal investigations.

The NPA will designate specialists to manage the analysis, separating their roles from those of police officers handling victim protection and other responses to ensure thorough information management. After the analysis, rules will be established for notifying users, but specific operational details are yet to be discussed.
