Import tools
Customs FX rates (weekly)
The official Japan Customs weekly exchange rates used for import valuation — as a page, a free JSON API and an embeddable widget. Not the market rate: the rate customs actually applies.
Open the tool →Tariff finder & landed-cost calculator
Japan's import tariff by HS heading in plain English, plus a calculator for duty, consumption tax and total landed cost.
Open the tool →Import compliance wizard
PSE, PSC, Giteki radio approval, food sanitation and more — answer a few questions and see which Japanese regimes apply to your product and who must act as importer.
Open the tool →Giteki certification checker
Search Japan's radio-equipment certification (技適) database in English — by brand, model or certification number.
Open the tool →Japan address toolkit
Postal-code lookup API and a converter that turns a full Japanese address into a correctly formatted English shipping label.
Open the tool →Why these tools?
Generic currency APIs and foreign tariff sites don't match what Japan Customs actually applies. These tools republish the official Japanese sources — customs notices, METI/MIC registers, Japan Post data — in formats importers can actually use.
