Japan Trade Statistics (Customs, HS × Country, Monthly)

Monthly Japanese import/export statistics by HS commodity code and partner country — straight from Japan Customs, no API key, no account.

This Actor queries the official trade statistics database of Japan Customs (Ministry of Finance, customs.go.jp) and returns the Commodity-by-Country table (普通貿易統計 品別国別表) as clean JSON: 9-digit statistical code, derived 6-digit HS subheading, partner country, quantities with units, trade value in actual JPY, and year-to-date cumulatives. Think of it as the Japanese counterpart of USITC DataWeb-style tooling — data back to 1988, published monthly.

Who is this for?

• Trade intelligence and policy analysts — measure tariff and trade-friction impact on specific commodity flows, monthly, at HS-code granularity.
• Sourcing and commodity research teams — who supplies Japan with what, and where Japanese exports go, tracked over time.
• Economists, journalists, and data teams — a scriptable alternative to a Japanese-first search interface, with values already converted from the source's 1000-yen units to actual JPY.

Country names come from the source's own English interface (customs' abbreviations, e.g. "USA", "NICARAG"); null quantities are the source's - (not published / no trade), passed through honestly rather than zero-filled.

Input example

{
  "tradeType": "import",
  "period": "2026-01..2026-06",
  "hsCodePrefix": "0901",
  "countryCode": "213"
}

• hsCodePrefix — required: 2/4/6-digit HS prefix or full 9-digit Japanese statistical code. Full-month dumps of everything are deliberately unsupported.
• period — a month (YYYY-MM), a range (max 6 months per run), or empty for the latest published month, discovered automatically.
• countryCode — optional 3-digit customs country code (official code list).

Pricing

Pay per result — see the pricing tab. A single commodity × country × month query is a handful of rows; a 6-month panel of an HS4 chapter across all partners is typically a few thousand.

FAQ

Where does the data come from? From the official Japan Customs trade statistics search system on customs.go.jp — retrieved directly from the customs servlet in its English mode, so column semantics and country names are the source's own English publication, not our translation. No e-Stat account, no appId, no API key.

Is this an official government service? No. Unofficial, independently built and maintained. The customs terms of use permit commercial reuse with attribution; the required 出典 statement is embedded in every record.

How fresh is the data? Monthly, with a publication lag of roughly two months (e.g., June figures available in late August). Leave period empty and the Actor finds the latest published month itself. Data reaches back to 1988. Note that recently published months may be provisional figures subject to later revision by customs.

Why is hsCodePrefix required? Two honest reasons: the upstream caps one query at 3,000 rows, and we don't do unbounded full dumps of public servers as a matter of design. If your query would exceed the cap, the Actor fails before downloading, with a message telling you to narrow the HS prefix or add a country filter.

Are commodity descriptions included? No — the commodity-by-country table publishes codes only; descriptions live in a separate tariff table upstream. hs6 gives you the international 6-digit subheading to join against any standard HS nomenclature you already use.

Any privacy concerns? None by construction: this is aggregate national statistics. Automated tests still assert no personal-data-shaped strings and full source attribution on every record.

What about server load? Two polite requests per month queried (search + CSV retrieval), ≥1.5 s apart, exponential backoff, hard request budget, no rate-limit evasion. Max 6 months per run keeps single runs modest by design.
