Weekly official Japan Customs reference exchange rate (税関長公示レート) used to convert import declaration values to yen under Article 4-7 of the Customs Tariff Law -- a live proxy to the Customs weekly CSV, not a real-time market rate. Source: Japan Customs (customs.go.jp), whose terms of use explicitly permit commercial use. Factual published data only; not a live FX quote or trading advice.
