Japan Renewable Energy FIT/FIP Certified Facilities

Japan's officially certified renewable-energy plants — solar, wind, hydro, biomass, geothermal — as English-schema JSON, from METI's public FIT/FIP disclosure.

This Actor delivers the 事業計画認定情報 (certified business plan) disclosure published monthly by METI / the Agency for Natural Resources and Energy on fit-portal.go.jp: facility ID, corporate operator, energy type, output in kW, municipality-level location, certification and operation-start dates, FIT period end, and solar decommissioning-reserve status. One prefecture per run, two upstream requests, everything parsed offline.

Unofficial tool. Not affiliated with or endorsed by METI, the Agency for Natural Resources and Energy, or the Government of Japan. Records are edited/processed data from the fit-portal public disclosure (出典：再生可能エネルギー電子申請サイトの事業計画認定情報を編集・加工して作成); the site's terms (政府標準利用規約 2.0, declared CC BY 4.0-compatible) permit commercial reuse with attribution and a processed-data notice — both are embedded in every record.

Who is this for?

• Renewable-energy investors and asset managers — screen Japan's certified capacity by region, technology, size, and operating status; identify operators and portfolios; track FIT period ends (repowering and secondary-market signals).
• Market analysts & consultants — capacity mapping, operator concentration, decommissioning-reserve compliance patterns in Japan's post-FIT transition.
• Data & AI teams — a structured alternative to 47 monthly Excel files behind changing download links.

What you get, and what we deliberately leave out

The upstream disclosure file contains substantial personal data — roughly a third of low-voltage solar operators are private individuals, listed with personal names, home addresses, and phone numbers. This Actor is built not to republish any of it:

• Individual operator names are withheld. operatorName passes a positive corporate/institutional test (legal-form designators, public bodies, cooperatives). Any name not positively identifiable as a legal entity becomes null with operatorNameWithheld: true. We accept losing some real companies to this filter; we do not accept publishing a person's name. (Measured on a live prefecture file: 1,120 kept / 565 withheld.)
• Locations are truncated to municipality level (市区町村). The upstream parcel-level address of a rooftop plant is effectively a home address; unparseable addresses fail safe to null.
• The operator's own address and phone columns are never read — they are deny-listed by header name, and automated legal tests verify that none of their values appear anywhere in the output.

If you need parcel-level locations or individual operators, this is the wrong tool — and we'd encourage you to think carefully before building that dataset from any source.

Input example

{
  "prefecture": "chiba",
  "energyType": "solar",
  "minOutputKw": 50,
  "maxItems": 5000
}

One run covers one prefecture (the upstream publishes one file per prefecture). For nationwide coverage, run all 47 prefectures — e.g., on an Apify schedule; that's 94 polite upstream requests in total, deliberately not crammed into a single run.

Pricing

Pay per result — see the pricing tab. A mid-size prefecture's solar fleet above 50 kW is typically a few thousand records.

FAQ

Where does the data come from? From the FIT/FIP certified-facility disclosure (事業計画認定情報) on fit-portal.go.jp, published by METI / the Agency for Natural Resources and Energy and refreshed monthly. The Actor resolves the current month's download link at run time and stamps asOfDate from the page's own reference date.

Is this an official government service? No. Unofficial, independently built and maintained. Every record carries the required attribution and the processed-data notice.

How complete is the coverage? The disclosure covers FIT/FIP-certified facilities and excludes solar below 20 kW (upstream policy). isOperating is true when an operation-start report month is published and null otherwise — legacy transition-certified plants may be operating without a report on file, and the Actor does not guess.

Why are some operator names null? See above: those are (or could not be proven not to be) private individuals, and we don't republish personal data. operatorNameWithheld: true marks them, and each run's summary reports the withheld count, so the filtering is visible rather than silent.

How fresh is the data? Monthly upstream refresh, sometimes with a publication lag of several months relative to the stated reference date — asOfDate always tells you what you actually got.

What about server load? Two requests per run, ≥1.2 s apart, exponential backoff on 429/5xx, explicit User-Agent, no rate-limit evasion. On persistent blocking the run fails visibly rather than working around it.
