APPI compliance and requirements, so personal data from Japan is handled the way the law expects.

What it is

What is the APPI and what is it used for?

The Act on the Protection of Personal Information is Japan's general data protection law. It governs how businesses obtain, use, share, secure and transfer information that identifies individuals, gives those individuals rights over their information, and sets separate duties for government bodies. A single independent regulator, the Personal Information Protection Commission (PPC), supervises its application across the private sector.

In practice the APPI asks a business to know what personal information it holds, why it holds it and who receives it, and to be able to demonstrate that when an individual, a customer or the regulator asks. Companies use a compliance programme to answer those questions once, consistently, instead of case by case under pressure.

Current text. The APPI is Act No. 57 of 2003. Amendments promulgated on 12 June 2020 took full effect on 1 April 2022, and the PPC publishes a consolidated English translation stating that all amended Acts were in full force as of 1 April 2023. Under the Act's triennial review, the PPC decided a system reform policy on 9 January 2026; its outline expected an amendment bill to reach the Diet as early as spring 2026 and to take effect roughly two years after approval. Until any amendment is enacted and in force, the current text applies.

Who it is for

Who needs APPI compliance?

The Act reaches almost every commercial handler of personal information about people in Japan. The earlier exemption for operators holding 5,000 or fewer records was removed by the 2015 amendments, and since the 2020 amendments the PPC can direct requests and orders to operators abroad. Organisations bring APPI work to Sterling for four reasons:

• Japanese customers ask for evidence. Enterprise buyers and group partners in Japan send privacy questionnaires and contract clauses on entrustment, security and incident reporting. A documented programme answers them quickly and consistently.
• A tender or partnership sets conditions. Outsourcing, platform and data-sharing deals often require proof of how personal information will be secured, supervised and returned. Build that evidence before the bid, not during it.
• The regulator's expectations are changing. Mandatory breach reporting, pseudonymised information and the 2026 reform policy mean yesterday's privacy notice and procedures may no longer match the law.
• A group company operates in or serves Japan. Headquarters running a GDPR or ISO/IEC 27701 programme need the Japanese entity, or the offshore service centre handling Japanese data, covered without a parallel system.

Compliance is the business's own obligation. A programme gives it structure and evidence; it does not transfer responsibility, and Sterling works alongside your legal advisers rather than replacing them.

Requirements

What are the main APPI requirements?

The Act is arranged in eight chapters. Private businesses are governed chiefly by the chapter on the obligations of businesses handling personal information; other chapters cover government duties, the PPC's powers and penalties. The list below summarises the Act at chapter and section title level, in plain language; the programme is checked against the current text and the PPC's rules and guidelines, with your legal advisers interpreting the points that need legal judgement.

• General provisions and government responsibilities: the purpose of the Act, its definitions, and the duties of national and local government to protect personal information.
• Obligations of businesses handling personal information: specifying and respecting the purpose of use, no inappropriate use, proper acquisition and notice of purpose, accurate data, security management measures, and supervision of employees and entrusted persons.
• Third-party provision and cross-border transfer: restrictions on providing personal data to third parties, including those in foreign countries, with records of provision and confirmation when data is received.
• Rights of individuals: information about retained personal data, requests for disclosure, correction, ceasing to use or deletion, explanation of reasons, and the handling of complaints.
• Data breaches: reporting qualifying incidents to the PPC and notifying the individuals affected, a duty in force since 1 April 2022.
• Pseudonymized and anonymized personal information: separate, tailored obligations for information processed so that individuals cannot be identified without additional data, or at all.
• Private-sector protection, the PPC and penalties: accredited personal information protection organisations, the PPC's supervision and monitoring powers, and the penal provisions.

Compliance process

How do you become APPI compliant?

There is no audit to pass and no certificate at the end. Compliance means the obligations are met in daily operations and the evidence exists when someone asks. The route has five stages.

1. 01
   Map the personal information in scope.Identify the Japanese entities, customers, employees and systems involved, the purposes of use and every party that receives the data, in Japan or abroad.
2. 02
   Gap analysis: compare current practice with the Act.Assess notices, consents, security, entrustment, transfers, request handling and breach readiness, then agree actions, owners and dates.
3. 03
   Build the compliance programme.Put policies, procedures, contracts and technical controls in place, and train the people who handle personal information.
4. 04
   Test through internal audit and review.Check that controls operate, rehearse a breach report and a disclosure request, and close findings with evidence.
5. 05
   Monitor, maintain and respond to change.Track PPC rules, guidelines and the triennial reform, and keep records, training and supervision current.

Check the route before you sign. Be wary of anyone offering an "APPI certificate": the Act has none. PrivacyMark is a separate scheme run by JIPDEC for Japanese companies, and any statement about it should be checked on privacymark.org. Legal interpretation belongs to qualified advisers in Japan.

Cost

How much does APPI compliance cost?

The cost of an APPI programme follows your data, not a price list. A distributor with one customer database in Japan needs far less than a platform processing millions of consumer records across borders. Sterling's proposal names each component and states everything that is included.

Timeline

How long does APPI compliance take?

Most programmes take three to six months, an estimate that depends on how well the data is already mapped, how many contracts need revising and how quickly decisions are made. Controls then need to run long enough to produce records that show they work.
