Japan APPI AI Controls Mapping for LLM Requests
A Japan APPI AI controls mapping should connect each applicable statutory duty to an owner, an enforcement point, a test, and retained evidence. This mapping covers purpose limitation, special care-required information, security measures, employee and processor supervision, domestic and foreign provision, incident response, and individual rights, with applicability nuances for entrusted LLM providers.
Japan's APPI attaches obligations to the handling of personal information and personal data, not to an AI label. A single LLM request can carry an employee name, performance note, medical detail, customer ID, and account history. The controls mapping has to follow that payload through purpose, access, provider, country, retention, and response handling.
I map each APPI duty to four fields: accountable owner, technical enforcement point, test, and evidence. The useful artifact is a row that links Article 23 to policy JP-PII-EGRESS-07, a denied request at 14:03, and the engineer who owns remediation. A matrix full of words such as governance and monitoring deserves the red pen.
Scope and purpose create the first control boundary
The Act on the Protection of Personal Information, linked through Japan's Personal Information Protection Commission, distinguishes personal information from personal data associated with a personal information database. Inventory prompts, attachments, retrieval sources, outputs, caches, and logs. Assign a stable system ID to every application and model route.
Articles 17, 18, and 21 map to a purpose control. Privacy or legal approves a specific purpose, the application supplies a controlled purpose code, and the policy decision point checks that code against identity, data category, model, and route. Test an allowed support summary and a denied experimentation request using the same customer transcript.
This control needs evidence of the stated purpose, notice, approval date, policy version, and two decision records. The mapping should also identify Article 20(2) where prompts can contain special care-required personal information.
APPI duties map to distinct AI controls
The mapping below uses the current PPC General Guidelines for implementation detail. It separates statutory duties because one broad privacy control hides different owners and failure modes.
| APPI duty | AI control | Operating test | Retained evidence | |---|---|---|---| | Articles 17, 18, 21: purpose and notice | Controlled purpose code bound to each model request | Send one approved and one out-of-purpose prompt | Purpose register, notice, policy version, permit and deny records | | Article 20(2): special care-required information | Prompt and attachment classification with consent or exception check | Submit a Japanese medical note and scanned certificate | Classification result, consent reference, expected and observed action | | Article 23: security control measures | Identity-aware access, data policy, model allowlist, fail-closed decision | Use an unauthorized role and unapproved endpoint | Access review, configuration, denial record, exception log | | Article 24: employee supervision | Role-based AI usage policy and escalation | Sample employee calls against approved routes | Training record, role mapping, request samples, corrective action | | Article 25: entrusted-person supervision | Provider restrictions, subprocessor review, deletion and incident terms | Compare live provider settings with the contract | Assessment, contract, settings export, review record |
The owner column belongs in the working matrix even though it is omitted here for width. Name one accountable person for each row.
Article 23 becomes enforceable at the HTTP request layer
Article 23 requires necessary and appropriate security control measures. The PPC General Guidelines describe organizational, human, physical, and technical measures, including rules for handling, access control, authentication, protection against unauthorized access, logs, incident readiness, and periodic review. AI traffic needs those measures translated into request decisions.
At the HTTP boundary, attach verified identity and role, classify the prompt, resolve purpose, check the model and country, then apply a versioned permit, redact, or deny action. Inspect responses for covered data introduced by the model. Record the result before returning the response to the application.
Test the control with a shared service credential carrying two delegated users. The finance user may access an approved analysis route. A developer using the same application credential should receive a different decision when the prompt contains customer account data. Preserve both records beside the identity mapping and policy version.
Provider role determines the Article 25 and 27 mapping
Model-provider treatment depends on the contract and actual use. A provider handling prompts solely to deliver the customer's requested service may fit Article 27(5)'s entrustment treatment, which connects directly to Article 25 supervision. A provider retaining prompts for an independent training purpose can change that classification and bring Article 27's third-party restriction into the analysis.
Map the decision explicitly:
| Provider fact | Control response | Evidence | |---|---|---| | Processing limited to documented customer instructions | Apply entrusted-person selection and supervision | Contract restrictions, settings, subprocessor list, review | | Provider receives independent-use rights | Route to privacy review before activation | Legal analysis, consent or applicable exception, approval | | Processing purpose or terms change | Suspend the route pending reassessment | Change alert, denial record, reassessment ticket | | Provider deletion commitment applies | Trigger and verify deletion on schedule or request | Deletion request, confirmation, retained metadata |
Articles 29 and 30 record and confirmation duties apply to defined third-party provisions and receipts. Match those controls to the classification. An LLM API call should not receive a misleading Article 29 label merely because it crossed a network boundary.
Article 28 requires country-aware route policy
Article 28 adds restrictions for provision to a third party in a foreign country, including entrusted processing abroad. Map every provider deployment to its actual recipient country and transfer mechanism. A vendor name alone lacks the processing location needed for this control.
The PPC's Foreign Third-Party Provision Guidelines explain information supplied for consent and ongoing measures under an equivalent-measures route. The operating control should track the recipient, country, contractual mechanism, equivalent measures, review method, review date, relevant foreign legal system, impediments, remediation, and suspension status.
Enforce country-model combinations inline. Then test a permitted Tokyo endpoint, a permitted foreign endpoint with a current transfer record, and an unapproved region. The evidence bundle should show one permit, one policy-based permit with transfer reference, and one denial. I consider runtime destination evidence mandatory for a credible mapping.
Incident, retention, and rights controls share an index
Article 22 addresses accuracy and deletion when use is no longer necessary. Article 26 covers prescribed leaks and similar events. Articles 32 through 35 support information, disclosure, correction, and cessation or deletion rights for retained personal data. A shared request index can connect these duties while keeping prompt content in a more restricted store.
Use a stable person reference, request ID, timestamp, application, purpose, data category, provider, country, policy version, and retention class as the index. Incident response can retrieve affected calls by time and route. The rights team can locate prompts, responses, vector-store entries, provider histories, and downstream records tied to one individual.
Test one correction, one deletion, and one incident reconstruction. Keep the search query, stores checked, provider correspondence, disposition, and access log. The physical detail matters: a reviewer should be able to scan one printed timeline and trace the same request ID across the incident ticket and signed event export.
Control assurance needs reproducible samples
The PPC General Guidelines call for confirming handling status and reviewing security measures. Add a cadence and trigger to each mapping row. Quarterly samples fit stable routes; provider changes, new countries, incidents, new data categories, and material model changes should trigger event-driven testing.
A complete mapping row contains the APPI duty, applicability decision, control objective, owner, implementation, policy version, test method, population, evidence location, exception process, review cadence, and failure response. Sample permit, redact, and deny records. Record the query and evidence hash so a second reviewer can reproduce the set.
Exceptions need scope, approver, reason, compensating control, expiry date, and closure test. Reviewers should treat a blank expiry field as a failed control. This is my committee-delete opinion for the article: annual policy review is too slow for model routes whose provider terms and processing regions can change during the year.
DeepInspect
DeepInspect sits inline between authenticated users or agents and HTTP-based LLM APIs. It evaluates identity, role, purpose context, prompt classification, route, model authorization, and policy before forwarding the request. The policy can permit an approved Japan route, redact defined data, or deny a model-country combination whose APPI review is missing or expired.
Each decision produces a tamper-evident record containing the request ID, identity, classification, destination, policy version, timestamp, and outcome. These records connect the technical enforcement point to the test and evidence columns in an APPI controls mapping. DeepInspect leaves purpose approval, notices, consent, provider classification, contracts, rights decisions, and PPC reporting with the organization.
