Why this happens

Cloud account credentials are commonly compromised through phishing, password reuse on breached sites, and SIM swap attacks. Two factor authentication via SMS provides only partial protection against modern attackers.

Once inside, attackers commonly download the full photo library before exiting. The original account compromise may have occurred weeks before the content surfaces online.

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 change passwords before the access logs are preserved. Account log retention is limited and changing the password may trigger log rotation that erases the intrusion evidence.

Five step removal process

  1. 1

    Preserve all evidence first

    Cloud account access logs showing the unauthorized access dates and IP addresses. The full list of devices and locations that have accessed the account.

  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
