Japan cash declaration check

Enter holdings reportable in Japan in the arrival list. Rates must convert each currency into JPY.

Inputs
One line: carrier ID; currency; amount; local currency per one currency unit. Example rates only: replace with the applicable official rate. Include every reportable instrument for this side; use different lists where definitions differ. Blank means zero. Max 200 lines. Use anonymous carrier IDs, not names. Rates must be local currency per 1 foreign unit; invert a quote given in the opposite direction. Japan: official weekly rates — select the week containing your crossing date. Canada: Bank of Canada rates — use the rate in effect at import/export under CBSA E667. For other profiles, confirm the applicable rate and period with the linked border authority; no universal customs rate is assumed. Local-currency preset: use the destination’s variant page, which starts with its own currency at rate 1; replace the amount with your holdings. Border guidance: EU external border, Great Britain, Northern Ireland, United States, Japan, Australia, Canada.

  • Japan: Currency, checks, promissory notes and securities. Gold over 1 kg at over 90% purity has a separate declaration, not assessed here. Ordinary entry/departure only; North Korea departures are excluded.
  • Include all members of one travelling family/group for GB, NI and US; individual carriers are tested separately elsewhere. Repeat for unrelated groups and each transit border. Never split holdings to avoid reporting.
  • Rates are user inputs, not live quotes. These are reporting thresholds, not carrying caps or clearance approval. Other restrictions and requests for disclosure may apply below the thresholds.
  • EU-internal and unlisted jurisdictions are not assessed. For China use the related China cash checker.

How it works

For each carrier, multiply each amount by local currency units per one unit of that currency and add the converted amounts. GB, NI and US apply the travelling family/group total. Other profiles check each carrier. Use one list per border because reportable instruments and conversion rates differ.

converted holdings = Σ(amount × rate)

US and Japan use a strict greater-than test; the other profiles include equality. Decimal arithmetic compares unrounded totals. Display totals have at most six decimal places. Replace the example rates with the applicable official customs rate. Rules were checked on 14 November 2026; historical commencement dates vary.

“Other” means unassessed, not exempt. EU refers to its external border, not every European country. NI arrivals from GB are tested, but the reverse journey has no UK cash declaration under this rule. National intra-EU rules, freight, sanctions and Japan–North Korea departures are outside this checker.
