Why this happens

AI undressing apps require only a single clothed photograph and produce results in under 60 seconds at near zero cost. Any public photo on social media can be the source.

Most AI undressing apps watermark their output, which provides forensic evidence of the specific app used. This evidence supports both removal and legal action against the operator.

Legal framework in Japan

Act on Prevention of Damage Caused by Provision of Private Sexual Image Records (Act No. 126 of 2014). Up to 3 years imprisonment or fine up to ¥500,000 for unauthorised provision. Up to 1 year for facilitating provision.

Japan enacted the Revenge Porn Prevention Act in 2014 in response to the Mitsuhashi Yuka case. The Act creates a specific criminal offence and obliges providers to expedite removal upon victim notification. The PPC enforces APPI rights against domestic and foreign processors.

Evidence to preserve

Do not: Do not engage with anyone offering to remove the AI generated content for a fee. This is a common follow on scam targeting recent NCII victims.

Five step removal process

  1. 1

    Preserve all evidence first

    Full page screenshot of every URL where the content appears. Any visible watermarks or metadata indicating the AI app used.

  2. 2

    File the Revenge Porn Prevention Act criminal complaint

    Report to local police or the national cybercrime unit. Safer Internet Association hotline can assist.

  3. 3

    Submit an erasure request under Act on the Protection of Personal Information (APPI) request for cessation of use

    Each major platform has a designated data protection contact. The request must cite the legal basis and identify the URLs. The platform has 30 days to respond. PPC accepts complaints for non compliance.

  4. 4

    Run a biometric scan to find every additional copy

    Content posted to one platform is rarely confined to one platform. ScanErase identifies every current hosting location in a single scan, including mirror copies and AI generated variants.

  5. 5

    File TAKE IT DOWN Act notices for covered platforms

    Use your scan report to file the federal 48 hour notice yourself, in parallel with your domestic rights. The two regimes are cumulative, not exclusive.

Statutory citations to include in your complaint
