Japan Grants & Subsidies API (jGrants) - Search and New Subsidy Alerts

Find Japanese government grants and subsidies (補助金・助成金, hojokin) that are open for applications, and get alerts for new subsidies every day. Data comes from the official jGrants public API run by the Digital Agency of Japan, which lists national programs and many prefecture and city programs.

• Official public API: no login, no API key, no proxy, no scraping of web pages.
• Clean JSON: application deadline, days left, maximum amount (JPY), subsidy rate, target area (with English prefecture names), company size, industry, purpose, and the full description as plain text.
• Monitor mode: returns only subsidies that are new since your last run. Schedule it daily and send the results to Slack, email, Google Sheets or your CRM.
• Several keywords in one run, merged and de-duplicated.
• Low cost: you pay per subsidy returned, and monitor mode only returns new ones.

What can you do with Japanese subsidy data?

• Subsidy consultants, tax accountants and SME advisors (補助金コンサル・士業): a daily list of new programs for your clients' region and industry.
• SaaS, equipment and construction vendors: find programs that pay for part of your product (IT導入, DX, 省エネ, GX) and use them in sales.
• Foreign companies entering Japan: see which national and regional incentives exist, with English labels for areas and company sizes.
• Media, newsletters and AI assistants: publish "new subsidies this week" automatically, or feed structured subsidy data to an LLM or RAG pipeline.

How to use it

1. Enter one or more keywords (Japanese works best: 補助金, 助成金, IT導入, DX, 創業, 省エネ, 設備投資, 海外展開, 観光, 人材育成).
2. Optionally filter by prefecture (English or Japanese), industry, company size and use purpose.
3. Run it. Each subsidy is one row in the dataset. Export to JSON, CSV or Excel, or use the Apify API.
4. For alerts, turn on monitor mode and add a daily schedule.

Input examples

IT and DX subsidies, closest deadline first:

{
  "keywords": ["IT導入", "DX"],
  "acceptingOnly": true,
  "sortBy": "acceptance_end_datetime",
  "sortOrder": "ASC",
  "includeDetails": true,
  "maxItems": 50
}

Daily alert of new subsidies for Tokyo:

{ "keywords": ["補助金"], "prefecture": "Tokyo", "monitorMode": true, "monitorId": "tokyo-all", "includeDetails": true }

Tips:

• Keywords must be at least 2 characters long (a jGrants rule).
• The prefecture filter returns programs targeted at that prefecture. Nationwide programs are labelled 全国. Use "prefecture": "全国" for nationwide programs only, or leave it empty for everything.

}

Other fields: subsidyNumber, catchPhrase, industry, institution, targetAreaDetail, projectEndDeadline, multipleApplicationsAllowed, matchedKeyword, isNew (monitor mode), scrapedAt. Attachments (guidelines, forms) are listed by file name only. Open the url page to download them from jGrants.

A RUN_SUMMARY record in the key-value store shows the keywords, how many subsidies were listed and returned, and why the run stopped.

Pricing

Pay per event: a small fee per subsidy returned (result) plus a tiny start fee. See the Pricing tab for current prices. You can set a maximum cost per run; the Actor stops cleanly when it is reached. Monitor mode keeps daily runs cheap because only new subsidies are returned.

Data source, attribution and terms

• 出典：Jグランツ (Source: jGrants, https://www.jgrants-portal.go.jp/), the subsidy application system of the Digital Agency, Government of Japan. API documentation: Digital Agency developer site.
• このデータは政府公式の補助金申請システム Jグランツの Web-API 機能を利用して取得した情報をもとに panda studio が加工して作成したものです。コンテンツの内容は日本国政府及び自治体によって保証されたものではありません。 (The data was retrieved with the jGrants Web-API and processed by panda studio: text converted from HTML, status, daysLeft and English area names added. It is not guaranteed by the Government of Japan or local governments.)
• This Actor is not affiliated with or endorsed by the Digital Agency or any government body.
• Every record has a source field with this attribution. If you publish or share the data, keep the attribution "出典：Jグランツ" and say that it was processed, as the jGrants Web-API terms require. Do not present it as if it were made by the government.
• Some application guidelines and forms may contain third-party rights. This Actor does not copy attachment files; get permission from the rights holder if you reuse them.
• The jGrants API is a beta service and allows up to 10 requests per second. This Actor sends at most about 2.5 requests per second, waits between requests and retries politely on errors. If the API is down for maintenance, the run fails with a clear message and nothing is charged for results.

Limitations

• Titles and descriptions are in Japanese, as published. Field names and area labels are in English. Add a translation step (for example an LLM) if you need English text.
• Not every Japanese subsidy is on jGrants. Some local programs are listed there but take applications on their own website; the description says so.
• 助成金 from the Ministry of Health, Labour and Welfare (employment subsidies) are included only if they are published on jGrants.

FAQ

Is there an API key or login? No. The jGrants public API is open. You only need an Apify account.

How does monitor mode remember? Subsidy IDs are saved in a named key-value store (jgrants-monitor-state) in your own Apify account. Use a different monitorId for each saved search.

Can I get subsidies that are closed or not yet open? Turn off "Only subsidies currently accepting applications". The status field shows open, upcoming or closed.

Can I use it with Make, Zapier, n8n or an AI agent? Yes. Call it through the Apify API or integrations, or connect it to an AI agent through the Apify MCP server.
