Sourced. Last verified 9 October 2026
Japan Privacy
- Status
- In force (last major amendment in force 1 Apr 2022). 2026 amendment (Act No. 56 of 2026) passed 10 Jul 2026, promulgated 17 Jul 2026: criminal penalty changes from 17 Jan 2027; main reforms by Cabinet Order, no later than 17 Jul 2028.
- Who it applies to
- Any business handling personal information in Japan, regardless of size. Foreign businesses are covered when they handle data of people in Japan in connection with supplying goods or services to people in Japan (Art. 171).
- Size thresholds
- No size or volume threshold. Breach reporting is triggered by sensitive data, risk of financial loss, malicious intent, or more than 1,000 people affected.
- Regulator
- Personal Information Protection Commission (PPC)
- Breach or incident reporting
- Preliminary report to the PPC promptly (guidance: about 3-5 days), final report within 30 days (60 days if malicious, e.g. cyberattack). Notify affected individuals promptly; public notice if direct notice is impossible.
- Deadline to answer personal data requests
- Being verified
- Data protection officer
- No legal requirement for a DPO. PPC guidance recommends assigning a responsible person (e.g. a Chief Privacy Officer).
- Local representative
- Being verified
- Sending data abroad
- Needs prior consent after telling people the destination country, an outline of its privacy system and the recipient's safeguards, unless the country is approved (EU, UK) or the recipient has equivalent safeguards (e.g. APEC CBPR). Monitor recipients regularly.
- Cookies and consent
- No cookie law. Cookie and browsing data are 'personally referable information': get consent before sharing it with a recipient who can link it to a person. Telecommunications Business Act needs notice, consent or opt-out for third-party cookies.
- Maximum penalty
- Up to JPY 100 million fine for companies (e.g. ignoring PPC orders or improper database provision); individuals up to 1 year in prison or JPY 1 million. From the 2026 amendment: administrative surcharges equal to money gained from certain violations.
