Scope and territorial reach
Scope
Japan’s Act on the Protection of Personal Information (個人情報の保護に関する法律) is the federal privacy law administered by the Personal Information Protection Commission (PPC). It applies to any “Personal Information Handling Business Operator” — effectively any business handling identifiable data of natural persons in Japan, with extraterritorial reach for foreign operators offering goods/services to Japanese residents.
The current text reflects the 2022 amendments — the most significant rewrite since the law’s 2003 introduction. EU adequacy is mutual since January 2019, meaning EU↔Japan transfers do not need additional safeguards.
Consent and lawful processing
APPI requires explicit consent (Art 18) for: (a) using personal information beyond the originally disclosed purpose, (b) providing personal information to third parties, (c) cross-border transfers (Art 24-2), and (d) handling sensitive data — race, creed, criminal record, medical history (Art 17-2).
For analytics tracking, the PPC has issued non-binding guidance recommending banner-style notices, but APPI does not have an explicit cookie-banner mandate equivalent to ePrivacy Art 5(3). In practice, opt-in consent is the safe default for cross-border transfers via Google Analytics and similar tools.
Data subject rights
- Disclosure (Art 28) — copy of data + processing purposes. No fixed response window — “without delay”.
- Correction, deletion, suspension (Art 29-30) — exercisable on the same “without delay” timetable.
- Cease use of personal information (Art 30, 2022 expansion) — broader than GDPR’s restriction right; can be invoked for any unfair processing.
Cross-border transfers
APPI Art 24 restricts transfers to jurisdictions outside Japan unless: (a) the recipient is in an adequacy-listed country (currently the EEA + UK), (b) the recipient has implemented “appropriate measures” equivalent to APPI, or (c) the data subject has consented after being told the destination country.
The 2022 amendments require disclosure of the destination country at the time of consent — not just generic “we may transfer abroad”. This is stricter than the equivalent GDPR Art 49(1)(a) consent path.
Breach notification
Mandatory since the 2022 amendments. Two thresholds:
- Promptly to the PPC upon discovering a covered breach (sensitive data, financial data, ≥1000 records affected, or breach for unlawful purpose).
- Promptly to affected individuals — except where contacting them is difficult and alternative public notice is given.
“Promptly” is interpreted as within roughly 3-5 days for the initial notification, with a final report within 30-60 days.
Enforcement
The 2022 amendments raised maximum corporate fines to ¥100 million (~€600k) or 1% of relevant turnover. Pre-2022 caps were ¥500k — a meaningful escalation. The PPC has historically focused on guidance over fines, but recent administrative orders against major retailers and platform operators signal a more enforcement-forward stance.
Notable: the LINE incident (2021) — Korean affiliate access exposure — triggered PPC administrative guidance and accelerated the 2022 amendment passage.

Where it applies — 1 jurisdictions
Seven principles (Article 5)
The constitutional backbone — every processing activity must satisfy all seven simultaneously.
-
01
Lawfulness of acquisition Art 17
Personal information must be acquired by proper means — no deception, fraud, or covert collection.
-
02
Purpose specification Art 17
Specify the purpose of use as clearly as possible before or at the time of acquisition.
-
03
Use restriction Art 18
Do not use personal information beyond the specified purpose without consent of the data subject.
-
04
Accuracy Art 22
Keep personal data accurate and up to date within the scope necessary to achieve the purpose of use.
-
05
Security control Art 23–25
Take necessary and appropriate measures to safeguard personal data, including supervision of employees and processors.
-
06
Transparency Art 21, 32
Notify or publicly announce the purpose of use; make matters concerning retained personal data accessible to data subjects.
-
07
Accountability Art 40
Endeavor to handle complaints appropriately and respond to PPC reports/inspections; document handling procedures.
-
08
Cease-use enforcement (2022) Art 35
2022 amendment broadened data subjects' right to demand cessation of use beyond original GDPR-equivalent grounds — including risk of rights infringement.
Six lawful bases (Article 6)
You must identify and document one before processing — and consent isn't always the right one.
Consent of the data subject
Default basis — required to use data beyond specified purpose or to share with third parties.
Based on laws and regulations
Processing required by Japanese law (tax, AML, employment).
Protection of life, body, or property
Necessary to protect human life or property when consent is hard to obtain.
Improvement of public health
Especially necessary for public health or sound development of children, and consent is hard to obtain.
Cooperation with public bodies
Cooperation with national or local government performing statutory duties; consent might impede the duty.
Academic research purpose
Personal data handled by academic institutions for research, where the purpose is academic in nature.
Eight data-subject rights (Articles 12–22)
What individuals can demand from you, with the response window and scope.
| Right | Article | Response | Scope |
|---|---|---|---|
| Notification of purpose of use | Art 32 | At collection | Right to know the purpose of use of one's retained personal data — must be publicly announced or disclosed on request. |
| Right to disclosure | Art 33 | At collection | Right to receive a copy of retained personal data — including in electronic form (added 2022). Response 'without delay'. |
| Right to correction / addition / deletion | Art 34 | At collection | Right to correct, add, or delete inaccurate retained data; response 'without delay'. |
| Right to cease use / erasure | Art 35 | At collection | 2022 amendment broadened: cessation when data is no longer needed, after a breach affecting the subject, or when there is a risk of rights/legitimate-interest infringement (broader than GDPR Art 17). |
| Third-party transfer log access | Art 26, 30 | At collection | Right to access records of third-party provision (sender/recipient logs) — controllers must keep such logs. |
| Right to lodge a complaint | Art 40 | At collection | Right to file a complaint with the controller, certified accreditation body, or directly with PPC. |
National addons
GDPR is a Regulation — directly applicable, no transposition required. But Member States layer additional rules on top via national acts.
| Country | National act | Stricter than GDPR baseline? | Note |
