Primary framework Act on the Protection of Personal Information (APPI) Supervisory authority [Personal Information Protection Commission (PPC)](https://www.ppc.go.jp/en/) Traffic-light rationale — Amber Opt-out and third-party data-provision rules are codified and enforceable, but dark-patterns, standardised opt-out signals, and clean-room-specific rules are absent, and reform of the opt-out scheme itself remains pending. #### Sub-modules (6) #### Cookies And TrackersAmber Cookie-derived individual-related information triggers third-party-provision consent-confirmation duties only when the recipient is likely to render it identifiable. Claims (1): - Where a business provides information about a living individual that is not itself personal information (e.g., website browsing history via cookies), and the recipient is likely to receive it in a form that becomes personal data, the provider must confirm the recipient has obtained the data subject's consent. #### Dark PatternsRed No dedicated dark-patterns prohibition was identified under current Japanese data-protection law. Claims (1): - No dedicated statutory prohibition on dark patterns in consent or data-collection interfaces was identified under current Japanese data-protection law. #### Opt Out SignalsRed No standardised, legally-recognised opt-out signal mechanism (e.g., GPC/DAA-equivalent) was identified under the APPI. Claims (1): - No legally-recognised, standardised browser/device opt-out signal mechanism analogous to the Global Privacy Control was identified under the APPI. #### Clean Rooms And DcrRed No clean-room / data-collaboration-room-specific rules were identified as distinct from general third-party-provision and joint-use requirements. Claims (1): - No rules specific to data clean rooms or data-collaboration platforms distinct from general third-party-provision and joint-use requirements were identified. #### Cross Context AdvertisingAmber Cross-context data sharing for advertising is governed by the general third-party-provision consent/opt-out framework rather than a CPRA-style 'sale'/'share' taxonomy. Claims (1): - Where a business provides information about a living individual that is not itself personal information (e.g., website browsing history via cookies), and the recipient is likely to receive it in a form that becomes personal data, the provider must confirm the recipient has obtained the data subject's consent. #### Direct MarketingAmber Direct marketing via shared personal data is governed by the opt-out scheme (PPC filing plus subject notice/accessibility), which functions as the suppression mechanism; reform would restrict abuse of this scheme. Claims (2): - Personal data may be provided to third parties for purposes such as marketing without consent if the operator notifies data subjects of opt-out matters (or makes them easily accessible) and files with the PPC. - The pending amendment would bar use of the opt-out scheme to provide personal data collected by deceit or improper means, or data that was itself received via another party's opt-out scheme, in response to observed abuse for fraud-adjacent list trading. Category narrative 94 words Cookie-derived browsing/behavioural data is regulated indirectly through APPI's 'individual related information' provision rule: a provider must confirm the recipient has obtained consent where the recipient is likely to combine such data into identifiable personal data. The opt-out scheme (PPC filing + subject notice) is the principal mechanism enabling third-party data provision, including for marketing purposes, without individual consent; the pending amendment would tighten this scheme by barring provision of improperly-collected data or data received via another party's opt-out filing. No dedicated dark-patterns prohibition or GPC/DAA-style recognised opt-out signal was identified in current Japanese law. no periodic updates on record for this sub-brief Evidence 6 Sources and claims (6) - Confirmed[IAPP](https://iapp.org/news/a/japan-updates-enforcement-rules-for-amended-appi) — Where a business provides information about a living individual that is not itself personal information (e.g., website browsing history via cookies), and the recipient is likely to receive it in a form that becomes personal data, the provider must confirm the recipient has obtained the data subject's consent.observed 2026-07-29 - Uncertain[IAPP](https://iapp.org/news/a/japan-s-dpa-publishes-interim-summary-of-amendments-to-data-protection-regulations) — No dedicated statutory prohibition on dark patterns in consent or data-collection interfaces was identified under current Japanese data-protection law.observed 2026-07-29 - Uncertain[IAPP](https://iapp.org/news/a/japan-s-dpa-publishes-interim-summary-of-amendments-to-data-protection-regulations) — No legally-recognised, standardised browser/device opt-out signal mechanism analogous to the Global Privacy Control was identified under the APPI.observed 2026-07-29 - Uncertain[IAPP](https://iapp.org/news/a/practical-notes-for-the-amended-appi-how-to-amend-privacy-notices) — No rules specific to data clean rooms or data-collaboration platforms distinct from general third-party-provision and joint-use requirements were identified.observed 2026-07-29 - Confirmed[IAPP](https://iapp.org/news/a/analysis-of-japans-approved-bill-to-amend-the-appi) — Personal data may be provided to third parties for purposes such as marketing without consent if the operator notifies data subjects of opt-out matters (or makes them easily accessible) and files with the PPC.observed 2026-07-29 - Probable[IAPP](https://iapp.org/news/a/analysis-of-japans-approved-bill-to-amend-the-appi) — The pending amendment would bar use of the opt-out scheme to provide personal data collected by deceit or improper means, or data that was itself received via another party's opt-out scheme, in response to observed abuse for fraud-adjacent list trading.observed 2026-07-29
