Meet Japan's APPI data protection rules with less effort

The APPI is the Act on the Protection of Personal Information (Act No. 57 of 2003), Japan's main data protection law. It sets rules on how businesses specify purposes, acquire, secure, share and transfer personal information, gives individuals rights to disclosure, correction and deletion, and requires breach reporting. The Personal Information Protection Commission (PPC) supervises and enforces it.

Any business that handles personal information in Japan must comply with the APPI's Chapter IV obligations, regardless of size. Under Article 171, the Act also applies to businesses outside Japan that handle the personal information of people in Japan in connection with supplying goods or services to them, so overseas SaaS providers serving Japanese users are usually in scope.

The PPC can request reports, carry out inspections, and issue recommendations and orders under Article 148. Breaching a PPC order, or providing a personal information database for illegal profit, can lead to imprisonment of up to one year for individuals, and the corporation can be fined up to 100 million yen under Article 184. The PPC can also publicly announce that an order was breached.

Yes. Article 26 requires a business to report leaks, loss or damage of personal data to the PPC, and to notify the affected individuals, where the incident is of a kind prescribed by the PPC rules, for example incidents involving sensitive data, risk of financial loss, wrongful purpose, or a large number of individuals. Businesses need an incident process that can assess and report quickly.

The APPI and GDPR share core principles, such as purpose limitation, security, individual rights and breach reporting, and the EU and Japan have mutual adequacy arrangements. The APPI differs in detail: it relies more on consent for third-party sharing and overseas transfers, has its own rules for pseudonymised and anonymised information, and uses PPC rules and guidelines rather than GDPR-style lawful bases.

Yes, with conditions. Article 28 requires prior consent, with information about the destination country's data protection system, unless the recipient is in a country the PPC recognises as equivalent, such as the EU and UK, or the recipient has a system meeting PPC standards, for example under contract. In that case the business must ensure continuing implementation of equivalent measures.

ISO 27001 helps with the APPI's security requirements, particularly Article 23 security control measures and the supervision of staff and entrusted processors under Articles 24 and 25. It does not cover the APPI's privacy obligations, such as purpose specification, consent for third-party provision, records of provision and individual rights, so those need separate controls and procedures.

Yes. OneClickComply supports the APPI today. Because controls are mapped across frameworks, evidence you already collect for ISO 27001, SOC 2 or GDPR counts towards the APPI's security and governance obligations. Automated evidence collection, AutoComplete policies and continuous monitoring support the work, and our in-house audit team can advise on APPI-specific privacy processes.
