What is APPI (Japan)?
APPI (Japan) stands for the Act on the Protection of Personal Information, formally known as Act No. 57 of 2003. It is Japan’s main data protection law that governs how personal information is collected, used, stored, and shared by private sector organizations. The law is enforced by Japan’s Personal Information Protection Commission (PPC), an independent government authority.
APPI applies to a wide range of organizations, including Japanese companies and foreign businesses that handle personal information about individuals in Japan. It is relevant across industries such as technology, finance, healthcare, education, retail, e-commerce, manufacturing, HR, and cloud services. Any entity that qualifies as a Personal Information Handling Business Operator is subject to the law.
The law has undergone several major revisions:
- In 2017, amendments introduced rules for anonymized data and stricter controls.
- In 2020, further changes strengthened user rights and breach notification rules. These came into effect in April 2022.
- In 2021, public and private sector oversight was unified under the PPC. Full enforcement began in April 2023.
- In June 2024, the PPC published an interim legal review. A revised draft of the law is expected by the end of 2025.
APPI is separate from the My Number Act, which governs Japan’s national ID system. There is no certification or registration process under APPI. Organizations are expected to meet legal obligations through internal governance and operational safeguards.
What are the requirements for APPI (Japan)?
There is no formal application process for compliance. Organizations must meet the requirements set out in Chapter IV of the law and demonstrate responsible handling of personal data.
Key requirements include:
- Clearly specifying the purpose of data use, and not using personal information for unrelated purposes without consent
- Acquiring personal information fairly and lawfully
- Notifying or publishing the purpose of use when collecting data
- Keeping personal data accurate and deleting it when no longer needed
- Implementing safeguards to protect data against unauthorized access, loss, or leaks
- Supervising employees and service providers who handle personal data
- Obtaining consent before sharing data with third parties, unless a legal exception applies
- Providing individuals with rights to access, correct, delete, or stop the use or sharing of their data
- Setting up systems to handle complaints and requests from individuals
Although APPI does not require compliance with international standards, many organizations use frameworks like ISO 27001, ISO 27701, or GDPR to support their controls.
The Personal Information Protection Commission (PPC) is the supervisory authority. It has the power to issue recommendations, orders, and penalties.
While the APPI (Japan) law includes multiple chapters covering obligations for government bodies, accredited organizations, and administrative procedures, our assessment focuses exclusively on the actionable compliance requirements under Chapter IV — the obligations of business operators handling personal data. This is the core section that applies to most private-sector organizations. Chapters related to government authority, accreditation processes, or transitional and administrative measures have been excluded, as they are either not applicable or impose no direct compliance requirements on businesses. Our assessment is designed for companies and institutions to whom Chapter IV applies.
Why should you be APPI (Japan) compliant?
Compliance with APPI is a legal obligation for any business handling personal data about individuals in Japan. It also provides operational and reputational benefits.
Benefits of compliance:
- Avoid legal penalties and orders from the PPC
- Meet legal requirements for cross-border data transfers
- Build trust with customers, regulators, and partners
- Show readiness for audits or vendor assessments

Risks of non-compliance:
- Fines of up to 100 million yen for serious violations

Being APPI-compliant helps organizations manage risk, operate lawfully, and maintain customer confidence in Japan.
