Japan APPI (Act on the Protection of Personal Information) 2022 Amendments

Japan's Act on the Protection of Personal Information (APPI), as amended by the 2020 revision effective April 1, 2022, introduced mandatory breach notification, expanded extraterritorial scope, tightened third-party provision rules, and significantly increased penalties. The Personal Information Protection Commission (PPC) administers the APPI with binding enforcement authority. The 2022 amendments require that all breaches involving "leakage, loss, or damage" of personal information meeting specific criteria be reported to the PPC within a "prompt" timeframe — subsequently clarified by PPC guidelines to mean within 3–5 days for initial report and 30 days for full report (60 days for cases involving "illicit purposes"). Affected individuals must also be notified when there is risk of harm.

The 2022 APPI amendments expanded the definition of "personal information requiring special care" (Sensitive Data) to explicitly include criminal records. They also introduced a new category: "personal information related to individuals' rights and interests in their economic lives" — covering information about financial status, loan defaults, and employment. Processing sensitive data requires opt-in consent, and third-party provision of sensitive data is prohibited without explicit consent in nearly all circumstances. The APPI now includes an extraterritorial provision (Article 24): foreign businesses handling personal information of persons in Japan in connection with providing goods or services are subject to PPC jurisdiction, and the PPC may make reports and recommendations to such foreign operators through their domestic representatives.

Japan's opt-out mechanism for third-party data provision (Article 27, Paragraph 2) — "Opt-Out Provision" — was significantly restricted by the 2022 amendments. Organizations that previously used opt-out registration with the PPC to provide personal data to third parties without consent can no longer use that mechanism for sensitive data, data obtained through fraud or unauthorized means, or data obtained from other opt-out registrants. The "anonymously processed information" (仮名加工情報, pseudonymously processed information) and "anonymized information" (匿名加工情報) frameworks provide specific processing pathways: pseudonymously processed information can be used for internal analysis without consent but cannot be provided to third parties; anonymized information can be provided to third parties if proper notice is given.

We implement APPI 2022 compliance with breach detection pipelines that trigger both the initial 3–5-day PPC report and the 30-day full report workflows, with automated classification of breach type against the mandatory notification criteria. Our third-party provision controls enforce the tightened opt-out restrictions and maintain PPC-compliant anonymously processed information workflows with appropriate internal/external access separations.
