Foreign-Currency Invoices in Japan: Yen Tax, Exchange Rates, Bank Details
How a business in Japan writes an invoice in US dollars, euros, won or another foreign currency: a foreign-currency invoice can still be a qualified invoice (適格請求書), only the consumption tax amount per rate has to be in yen, which exchange rate to use, when to round, a worked example, and how to give bank details for a payment from abroad. Based on National Tax Agency (NTA) and e-Gov sources as of October 23, 2026.

Who this is forSole proprietors living in Japan and Japanese corporations that issue invoices in a foreign currency to clients in Japan or abroad. If you live outside Japan and bill a Japanese client, different consumption tax and withholding rules apply.
Short answer
- A foreign-currency invoice can be a qualified invoice (適格請求書). The required items are the same as for a yen invoice and may be written in a foreign language or currency, except the consumption tax amount for each tax rate (消費税額等), which must be stated in yen[1][2].
- Convert to yen the same way sales are converted for income tax or corporate tax: in principle, the TTM on the transaction date. If that is impractical when you issue the invoice, a reasonable method used consistently, such as the TTM on the issue date, is also accepted[1][2][3].
- Round only once per tax rate, after the tax is in yen. Rounding the foreign-currency tax first and then converting it is not allowed. The tax shown in the foreign currency is for reference only[1].
- Example: USD 1,234.56 at 10% with a rate of 1 USD = ¥150.25 gives 1,234.56 × 150.25 × 10% = 18,549.264, so the consumption tax amount is ¥18,549 (fraction dropped)[1].
- An invoice to an overseas client may fall under the export exemption (輸出免税) or be outside the scope of Japanese consumption tax, in which case there is no obligation to issue a qualified invoice. For bank details, banks typically ask for the bank name in English, SWIFT code, account number, and the account name and address in Latin letters[4][5][6].

A foreign-currency invoice can be a qualified invoice: only the tax amount must be in yen
Question 68 of the NTA's Q&A on the qualified invoice system says that for transactions in US dollars or other foreign currencies, a qualified invoice needs the same items as a yen invoice. Apart from the consumption tax amount for each tax rate, those items may be written in a foreign language or currency[1]. The consumption tax amount must be converted to yen, even for a foreign-currency transaction[1][2].
| Required item | On a foreign-currency invoice |
|---|---|
| Issuer's name and registration number (登録番号) | May be in a foreign language. The registration number stays as T plus 13 digits[4][1] |
| Date of the transaction | May be written in a foreign-language format[4][1] |
| Description (and a note if the reduced rate applies) | May be in a foreign language[4][1] |
| Total consideration for each tax rate, and the rate | May be in the foreign currency[4][1] |
| Consumption tax amount for each tax rate | Must be the amount converted to yen[1][2] |
| Name of the business receiving the invoice | May be in a foreign language[4][1] |
- A tax amount in the foreign currency (for example, Tax amount USD 123.45) is not a required item; it is shown for reference only[1]. If you show it, mark it "reference" (参考) so it is not confused with the yen amount.
- If your client calculates its input tax credit by adding up the tax amounts on the invoices it receives, it uses the yen tax amount on your invoice. The NTA says this is fine even if your conversion differs from the client's own method[1].
Choosing the exchange rate: TTM in principle, or a reasonable method used consistently
The consumption tax amount is converted to yen in the same way as the consideration itself (Consumption Tax Basic Circular 10-1-7): following the method used to convert foreign-currency sales for income tax or corporate tax[1][3]. That method uses the TTM on the date the transaction is recorded. TTM is the midpoint between the bank's telegraphic transfer selling rate (TTS) and buying rate (TTB)[7][8].
| Issuer | Rule | Allowed if used consistently |
|---|---|---|
| Sole proprietor | TTM on the transaction date[7] | TTB on the transaction date for sales; the rate at the end of the previous month or the start of the month; an average over a period of up to one month[7] |
| Corporation | TTM on the transaction date[8] | TTB on the transaction date for sales; the rate at the end of the previous month or the start of the month; an average over a period of up to one month[8] |
In principle, use the rates of your main bank[7][8]. If this is impractical, for example because the transaction-date rate is not known yet when you write the invoice, a reasonable method is also accepted, such as consistently using the TTM on the day you issue the qualified invoice or the rate on the settlement date[1][2].
- Decide which day, which bank and which rate (TTM, TTB and so on) you will use.
- Keep using the same method for every invoice[1][2].
- Show the rate and its basis on the invoice, for example "換算レート 1 USD = ¥150.25 (2026/10/22 TTM)". The rate is not a required item, but Question 68's sample also shows the TTM used, above the table. Showing it lets your client check the yen tax amount[1].
Order of calculation and rounding: convert to yen, then round once per rate
Question 68 gives four ways to arrive at the yen tax amount. In every one, the rounding is applied to the tax amount once it is in yen[1].
| Method | Order of calculation |
|---|---|
| 1 | Consideration per rate (foreign currency, tax excluded) × TTM → yen consideration × tax rate → round[1] |
| 2 | Consideration per rate (foreign currency, tax included) × TTM → yen consideration × 10/110 (8/108) → round[1] |
| 3 | Consideration per rate (foreign currency, tax excluded) × tax rate → interim tax in foreign currency × TTM → round[1] |
| 4 | Consideration per rate (foreign currency, tax included) × 10/110 (8/108) → interim tax in foreign currency × TTM → round[1] |
- In methods 3 and 4, the interim tax in the foreign currency must not be rounded. Rounding applies only to fractions of a yen, so there is nothing to round until the tax is in yen[1].
- In methods 1 and 2, rounding the yen consideration is optional. That rounding is not the rounding of the consumption tax amount[1].
- The consumption tax amount is rounded once per tax rate on each qualified invoice. You may round up, round down or round to the nearest yen[1].
Worked example: an invoice in US dollars
| Item | Amount | Calculation |
|---|---|---|
| Website design | USD 1,200.00 | |
| Additional banners (3) | USD 34.56 | 11.52 × 3 |
| Subtotal (10% rate, tax excluded) | USD 1,234.56 | 1,200.00 + 34.56 |
| Consumption tax 10% (reference) | USD 123.45 | 1,234.56 × 10% = 123.456 → fraction of a cent dropped |
| Total (amount billed) | USD 1,358.01 | 1,234.56 + 123.45 |
| Exchange rate | 1 USD = ¥150.25 | TTM on the transaction date, as an example |
| Consumption tax amount in yen, 10% rate | ¥18,549 | 1,234.56 × 150.25 × 10% = 18,549.264 → fraction of a yen dropped[1] |
Method 1 and method 3 both give ¥18,549. Under method 1, rounding the yen consideration of ¥185,492.64 down to ¥185,492 before applying 10% gives ¥18,549.2, which is also ¥18,549[1]. The amount billed stays USD 1,358.01; the yen tax amount is not added to the total.
Totals block for the example above (in Japanese, as printed on Japanese invoices)
小計(10%対象) USD 1,234.56 消費税(10%)(参考) USD 123.45 合計 USD 1,358.01 消費税額等(円換算)10%対象 18,549円 換算レート 1 USD=150.25円(2026/10/22 TTM)
Common mistake: rounding the foreign-currency tax before converting
Multiplying the reference tax of USD 123.45 by the rate gives 123.45 × 150.25 = 18,548.36…, or ¥18,548, which is ¥1 off the correct ¥18,549. The interim foreign-currency tax may not be rounded, so this calculation cannot be used[1]. Multiplying the unrounded USD 123.456 by 150.25 gives ¥18,549.264, the correct result.
Billing an overseas client: check separately whether consumption tax applies
When the client is abroad, first check whether Japanese consumption tax applies at all. This section covers only the starting points for that decision.
- Domestic or overseas transaction: a service is, in principle, located where it is performed. "Electronic services" (電気通信利用役務の提供) such as distributing e-books, music or advertising online are located by the recipient's address. Overseas transactions are outside the scope of consumption tax[9].
- Export exemption: services provided to non-residents (非居住者) are generally exempt as exports. Services the non-resident benefits from directly in Japan are not exempt, such as transporting or storing goods located in Japan, or meals and accommodation in Japan[10][5].
- Proof: to apply the export exemption to services for non-residents, keep the contract or other documents containing the required details for seven years[10].
- Obligation to issue a qualified invoice: it applies to taxable sales made in Japan, when a business customer (other than a tax-exempt business) asks for one. Sales exempt from consumption tax, such as export-exempt sales, are excluded[4].
Billing a client in Japan in a foreign currency: the payer converts for withholding
If you are a registered issuer and bill a client in Japan in a foreign currency for a taxable domestic sale, you still have to issue a qualified invoice when the client asks[4]. The rules above apply in the same way. Whether to bill in a foreign currency is agreed with the client.
If the fee is subject to withholding tax (源泉徴収), the payer converts the foreign-currency fee to yen. When paying in the foreign currency, the payer generally uses the TTB on the date payment is due. If the contract says the foreign-currency amount is paid in yen, the yen amount follows the conversion method in the contract[11]. When the fee is paid in the foreign currency, the rate on the due date is not known when you write the invoice, so the withholding amount cannot be fixed on the invoice. Which fees are covered and at what rate is explained in Withholding tax on invoices in Japan.
Bank details for a payment from abroad: SWIFT code, account name and address in Latin letters
To be paid from abroad, give the remitter your Japanese bank and account details in English. MUFG Bank lists the following items to give the remitter[6]. Items and formats differ between banks, so also check your own bank's guide to receiving payments from overseas.
| Item | What to write |
|---|---|
| Receiving bank | The bank's English name. If the remitter is asked for a branch name and bank address, give the name and address (in English) of the branch that holds your account[6] |
| SWIFT code (BIC) | 8 characters. MUFG Bank uses one code for all its branches in Japan; if 11 characters are required, add XXX at the end[6] |
| Account number | The 3-digit branch number plus the 7-digit account number[6][12] |
| Beneficiary name | The account name in Latin letters. If you have registered an English name with the bank, use exactly that name[6] |
| Beneficiary address | In English[6] |
- No IBAN or ABA: Japan does not use IBAN or ABA routing numbers. Tell the remitter so if asked[6].
- Intermediary bank: some banks, such as Rakuten Bank, ask you to have the remitter include intermediary bank details in the payment instruction[12].
- Currency received: if you name a yen account, the bank converts the payment to yen at its own rate. To receive the foreign currency as it is, name a foreign-currency deposit account in the same currency[6].
- Fees: your receiving bank may also charge a fee when the payment arrives[6]. In practice, agree who pays the bank charges at the quote or contract stage and repeat it in the invoice notes.

FAQ
Do I have to show the exchange rate on the invoice?
It is not a required item. What is required is the consumption tax amount converted to yen[1]. Question 68's sample also shows the TTM used, above the table. Showing the rate and its basis lets your client check the yen tax amount and saves questions.
My client converts with a different rate. Do I need to change the tax amount?
No. When the client adds up the tax amounts on the invoices it receives, it may use the amount on your invoice even if its own conversion method differs[1]. As the issuer, keep using the method you chose[2].
Can I leave out the tax amount in the foreign currency?
Yes, as far as the qualified invoice requirements go. The foreign-currency tax is shown for reference only[1]. If you show it, mark it "reference" (参考) to tell it apart from the yen amount.
I am not registered for the qualified invoice system. Do I still need the tax amount in yen?
The yen tax amount is an item of a qualified invoice, and the duty to issue qualified invoices applies to registered issuers (適格請求書発行事業者)[4]. An unregistered business's invoice is not a qualified invoice, so this item is not required.
Is the calculation the same for euros or won?
Yes. Question 68 uses US dollars as the example, but the answer covers "foreign-currency transactions such as US dollars"[1]. Even for a currency worth little per unit, such as the won, you still convert to yen first and round once per tax rate.
