Japan's National Police Agency, Financial Services Agency and five other ministries and agencies on the 7th asked five major platform operators to strengthen countermeasures against impersonation scam advertisements spreading across social media. The request was sent to Google, LINE Yahoo, Meta, TikTok Japan and X Corp after investment scam ads using deepfake technology (AI-generated fake audio or video) circulated with celebrities' images and voices used without permission, contributing to rising losses from SNS-based investment fraud. The authorities highlighted three policy pillars, including identity verification for advertisers. In related fraud data, YouTube accounted for 27.1% of contact methods in SNS-type investment scams. The move was framed as administrative guidance under Japan's Administrative Procedure Act and not as a punitive disposition.
