Get Japanese government subsidy and grant programs as clean JSON, including city programs that jGrants does not list.
Most Japanese subsidy tools read only jGrants, the Digital Agency's portal. jGrants covers national programs and many prefectures, but big cities usually publish their own programs only on their own websites. For example, on 2026-10-27 jGrants had 0 open city programs from Yokohama or Nagoya. This Actor fills that gap and returns everything in one schema.
Sources
source | Coverage | How |
|---|---|---|
jgrants | National ministries and agencies, many prefectures (e.g. Tokyo), some cities | Official jGrants public API |
yokohama | Yokohama City business support programs (中小企業支援) | Crawls the official city website |
nagoya | Nagoya City industry programs (産業振興) | Crawls the official city website |
More cities will be added based on usage.
Output
One item per program:
| Field | Meaning |
|---|---|
maxAmountYen | Largest cap stated on the page, in yen (5億円 → 500000000) |
subsidyRate | As written, normalized: 1/2, 2/3, 20%以内, 定額 |
applicationStart / applicationEnd | ISO dates. Japanese era years (令和・平成) are converted. Either can be null |
status | open, upcoming, closed (judged against today in JST), or unknown when the page states no dates; these are often year-round programs |
periodText | The sentence the dates came from, so you can check them |
Input
| Field | Default | |
|---|---|---|
sources | all | Any of jgrants, yokohama, nagoya |
keywords | none | Keep programs whose title contains any keyword (Japanese), e.g. 省エネ, 創業, DX |
statuses | open, upcoming, unknown | Add closed to include past programs |
maxItems | 1000 | You pay per result |
A full run takes about 3 minutes, because city websites are crawled politely on purpose (at most one new request per second per site). Run it on a daily or weekly schedule.
Limitations
- City fields are extracted from free-form Japanese web pages with rules, not from a database. Always check
urlbefore applying.periodTextshows where the dates came from. - When a page lists several rounds (第1回, 第2回), the round that includes today is returned. If none does, the latest round is returned.
- Dates written without a year are read as the same Japanese fiscal year (April to March) as the page's last update. Deadlines like 「毎年度1月31日」 become the next upcoming date.
- If only a start date is known,
statusisopenonly when the program started in the current fiscal year. Otherwise it isunknown. - Many city programs close early when the budget runs out (先着順).
status: openmeans the deadline has not passed. It does not mean budget is left. - Only facts (name, dates, amounts, rates, link) are output. Page text is not copied.
- jGrants items have no
subsidyRate(the list API does not return it). - Not affiliated with the Digital Agency, Yokohama City or Nagoya City.
