Freelancing in Japan while serving clients abroad is increasingly common — and increasingly confusing at invoice time. Your accounting software is built for the domestic market, your client expects an English invoice in their currency, and the tax rules are different for cross-border work. This guide walks through what actually matters.

1. Consumption tax: usually zero on exports

The first thing that trips people up: you generally do NOT charge 10% Japanese consumption tax (消費税) on services provided to a foreign business. Such transactions are treated as outside the scope of consumption tax (不課税 / tax-exempt for export of services).

On your invoice: - Show the tax line as 0% (or omit the tax and state the net amount clearly). - Add a short note: "Tax-exempt: cross-border service under Japanese Consumption Tax Law."

This both reassures your client and documents why no tax was added. (For domestic clients, the normal インボイス rules apply — that's a separate case.)

2. SWIFT/BIC codes are mandatory for international transfers

A domestic Japanese account (普通 + 7-digit number) is not enough for an overseas wire. You need:

  • SWIFT/BIC code — 8 or 11 characters identifying your bank internationally.
  • IBAN — required for many European transfers.
  • Intermediary / correspondent bank — sometimes needed for smaller Japanese banks; ask your bank.
  • Account holder name in romaji — exactly as registered.

List these clearly in a "Payment Details" block. Missing a SWIFT code is the #1 reason overseas payments stall.

3. Exchange rates: pick a convention and state it

If you bill in a foreign currency (USD/EUR), decide and disclose:

  • The rate you used (e.g. ¥150.00 / USD).
  • The date and source (e.g. "TTM as of 2026-06-22").

Many freelancers bill in JPY and add the foreign-currency equivalent for the client's reference, or bill in the client's currency and keep the JPY equivalent for their own bookkeeping. Either works — just be consistent and transparent.

4. Withholding tax (源泉徴収): mostly domestic

If a Japanese company pays an individual for certain services, they may withhold income tax (typically 10.21%) and show it as a deduction. On the invoice you'd show:

  • Subtotal → consumption tax → total → minus withholding → net amount payable.

For genuinely overseas (non-resident) clients this usually does not apply, but it matters if you also invoice Japanese companies. Know which case you're in.

5. Format details that signal professionalism

  • Dates: avoid 2026年6月22日 for overseas clients — use 22 Jun 2026 or June 22, 2026.
  • Honorifics: drop 御中 on English-only invoices; just use the company name.
  • Numbers: be explicit about currency and thousands separators ($1,540.00).
  • PO / reference number: include your client's PO so they can match it.

6. Tooling: stop re-typing into Excel

Most freelancers end up exporting from their accounting software and rebuilding the invoice in Excel — slow and error-prone. The better path is to reuse the data you already have. If you use freee, a tool like BridgeInvoice connects via OAuth, pulls the invoice, and generates a professional English (or bilingual) PDF that already handles:

  • Consumption-tax exemption notes for cross-border work
  • SWIFT/IBAN/intermediary bank fields
  • Exchange-rate conversion with date/source
  • Withholding tax and net-payable
  • インボイス-compliant tax breakdown for your domestic clients

Summary

Billing overseas from Japan isn't hard once you know the moving parts: zero consumption tax on exports (with a note), complete bank details including SWIFT, a stated exchange rate, and clean Western formatting. Reuse your accounting data rather than retyping it, and your invoices will go out faster and get paid sooner.
