Japan Subsidies & Grants Scraper — official jGrants data, structured

Extract Japanese government subsidies and grants (補助金・助成金) from jGrants, the Digital Agency's official subsidy application portal. Keyword search, open-application filtering, and full detail enrichment — amounts, subsidy rates, deadlines, target industries, target regions, employee-size conditions, full descriptions and application-document metadata — returned as clean structured JSON.

The source is an official government API: legal to use, token-free, and exceptionally stable.

FAQ

Is this legal? Yes. jGrants' public API is operated by Japan's Digital Agency precisely so subsidy information can be reused programmatically. No personal data.

Why is maxAmountJpy sometimes 0 or fields null? The portal aggregates records from many institutions; not every field is populated at the source. title, targetArea, acceptance dates and officialPageUrl are reliably present.

Can I get the application files themselves? The API embeds files as base64 (several MB each), which would blow up dataset items — this Actor returns file names + sizes instead, and every record links to its official page where files are downloadable.

Does it include municipal subsidies? It includes everything published on jGrants (national + prefectural + municipal). Some purely local subsidies are never posted to jGrants — that subset is out of scope.

Something broken? Open an issue on this Actor's page — fixes ship within 24 hours.
