name	japan-gov-chart-data-tracer
description	Use when the user identifies a specific Japanese government chart, table, figure, source note, or statistic and wants its 元データ or reproducibility traced. Do not use to brainstorm KPIs or generally search e-Stat.

Japan Gov Chart Data Tracer

Work backward from an identified official figure or number to its source data and transformations.

Do Not Use For

• “What should we measure?” or candidate indicators; use japan-gov-kpi-finder.
• Searching, retrieving, or analyzing an e-Stat table without an identified upstream figure; use japan-gov-estat-data-analyst.
• Broad evidence collection without a figure, table, source note, or quoted statistic.

Workflow

1. Identify the document, edition, figure/table number, title, page or section, source note, and displayed values. Ask only for the missing identifier needed to disambiguate.
2. Inspect the official landing page, linked Excel/CSV, statistical appendix, and source note.
   • Follow ../../references/official-url-model.md and ../../references/egov-whitepaper-route-map.md.
   • Cache only needed files under ../../references/download-cache-policy.md.
3. Trace the chain from rendered figure to reproduced table, original survey/table, and downloadable data. Record every aggregation, rebasing, deflation, seasonal adjustment, estimate, or author calculation disclosed.
4. Classify the result as original data, official reproduced data, processed estimate, commissioned survey, or rendered-only.
5. If the chain resolves to an e-Stat statsDataId and retrieval or reanalysis is requested, pass the identified ID, filters, and transformation notes to japan-gov-estat-data-analyst and continue in the same task.
6. Attempt one official data-page route and one named-survey route after the document links. If neither verifies the source, stop and report the unresolved link.

Output

Figure/statistic	Document location	Source-data candidate	Transformation	Format/ID	Reproducible?	Caveat

Guardrails

• Do not call a chart reproducible when only a rendered PDF or incomplete source note exists.
• Do not erase transformations, survey scope, breaks in series, or estimation.
• Prefer official APIs/tables over bulk scraping and cite official landing pages.
