Pay in Yen or Your Home Currency? Card Machines in Japan

When a card machine or ATM in Japan asks whether you want to be charged in yen or in your home currency, choosing yen is usually the cheaper option. Picking your home currency hands the exchange rate to the shop or the ATM operator instead of your own bank, and that rate normally carries a markup on top of the wholesale rate. The service is called dynamic currency conversion (DCC), it is optional under the card network rules, and you are allowed to decline it.

This article explains the exact prompt you will see in Japan, what the markup can cost you on a typical hotel bill, and which answer to give in each of the three places the question comes up.

What is the “pay in your own currency?” prompt in Japan?

Dynamic currency conversion converts a yen amount into your card’s billing currency at the moment of the transaction, rather than letting your card issuer convert it later. Seven Bank, which runs the ATMs inside 7-Eleven stores, describes it plainly: DCC lets overseas visitors choose whether the transaction is settled in their home currency or in yen.

If you choose your home currency, the converted amount is fixed there and then, at the ATM or terminal. If you choose yen, the transaction settles in yen and your own bank works out the home-currency figure when the bill is issued.

Seven Bank lists DCC as available on Visa and Mastercard, around the clock, and not available on JCB, Discover, UnionPay, American Express or Diners Club (per its overseas-card page, as of October 2026). On a Visa withdrawal, the currency question appears as a distinct step after you have already chosen the yen amount — so seeing the yen figure on screen does not mean the currency decision is behind you.

Japan Post Bank gives the same warning from the other direction: when you withdraw yen with certain overseas cards, the settlement amount may be finalised in your card’s home currency, whereas settlement is normally finalised when the card transaction is billed.

Why paying in yen is usually cheaper

Two different organisations can convert your money, and they do not price it the same way.

If you pay in yen, your card issuer and its network do the conversion using their own exchange rate, plus whatever foreign transaction fee your card carries. If you accept DCC, the conversion is done by the merchant, the branch or the ATM operator — Visa’s rules require receipts for a DCC transaction to state that the conversion is conducted by the merchant, branch or ATM acquirer, not by Visa.

That matters because the DCC rate includes a markup that the merchant or ATM operator has agreed commercially. Visa’s rules require a DCC receipt to show the currency conversion rate and the “currency conversion commission, fees, markup, or margin on the exchange rate over a wholesale rate or government-mandated rate” (Visa Core Rules and Visa Product and Service Rules, 18 April 2026 edition). In other words, the markup is a known, disclosable number — it is just not always a small one, and it is added on top of anything your own bank charges.

How much does DCC cost on a ¥30,000 hotel bill?

The useful thing about a markup expressed as a percentage is that you can price it in yen without knowing the exchange rate. A markup of 5% on a ¥30,000 bill costs the same ¥1,500 of extra value whether you are billed in dollars, euros, pounds or Australian dollars.

The table below is illustrative arithmetic on a ¥30,000 charge, not a quoted price from any provider. Use it to judge whether the markup on your screen is worth accepting. Markups are set per merchant or per ATM operator, so the number you see is the number that applies to you.

Compare that with your own card’s foreign transaction fee, which is typically a single low percentage and is charged whichever currency you choose. If the DCC markup is higher than your card’s own fee, paying in yen leaves you better off; if the terminal discloses a markup lower than your card’s fee, the arithmetic can go the other way. The point is that the screen is asking you to make a price comparison, so treat it as one.

Where you will see the prompt: terminals, ATMs and online

The same decision shows up in three different situations in Japan, and the right answer is not identical in all three.

What to tap: the cheat line

On any Japanese terminal or ATM screen that offers two currencies, choose the option labelled JPY, Japanese yen, or wording such as “without currency conversion”. Decline anything phrased as “pay in USD/EUR/GBP”, “conversion to your currency”, or “lock in today’s rate”.

If a member of staff has already produced a receipt showing your home currency and you had not agreed to it, you are entitled to say so. Visa’s rules require a merchant, ATM acquirer or branch offering DCC to inform you that DCC is optional, to avoid language or procedures that make you choose DCC by default — pre-selecting the DCC option is the example the rules give — and to obtain your express agreement. In a card-present transaction the rules require you to agree by interacting with a customer-facing screen or handheld device yourself.

The rules also say the merchant or ATM operator must not impose any additional requirement on you in order to have the transaction processed in the local currency. Asking to be charged in yen is therefore a normal request, not a favour.

What the receipt should show

If you do accept DCC, the paperwork is supposed to let you check the price. Under the Visa rules, a DCC receipt must carry the amount in both the local currency and the transaction currency, the currency conversion rate, the conversion commission or markup over a wholesale or government-mandated rate, a clearly visible statement that you were offered a choice of currencies and expressly agreed, a statement that the conversion is being done by the merchant, branch or ATM acquirer, and a customer service contact.

Keep the receipt. Those required lines are what you would use to query a charge with your card issuer later.

Do EU rules help if your card was issued in Europe?

If your card was issued in the EU, the markup is meant to be disclosed in a comparable form. Regulation (EU) 2021/1230 on cross-border payments requires currency conversion charges to be expressed as a percentage markup over the latest available euro reference rates published by the European Central Bank, and states that the markup “shall be disclosed to the payer prior to the initiation of the payment transaction”. It also requires the party offering conversion at an ATM or point of sale to inform the payer of the possibility of paying in the currency used by the payee.

That regulation replaced the regime introduced by Regulation (EU) 2019/518, which had amended the earlier cross-border payments regulation and added the ATM and point-of-sale disclosure duties from 2020 and 2021. The 2019 text is explicit about the reasoning: as its recitals put it, where conversion charges are not transparent it “increases the risk of payers choosing expensive currency conversion options”, and the payer should be able to refuse the service and pay in the currency used by the payee instead.

Two caveats. These are EU rules, so they bind EU payment service providers and the parties covered by the regulation rather than every shop counter in Japan — a Japanese merchant’s screen is not obliged to show you an ECB-based percentage. And the EU’s own consumer guidance notes that currency conversion fees sit outside the EU rules that cap what banks may charge for cash withdrawals in another EU country, while still requiring ATM operators to inform you of fees and currency conversion costs before you complete a withdrawal.

Does paying in yen avoid every fee?

No. Declining DCC removes the merchant’s or ATM operator’s conversion markup. It does not remove the fees on your side of the transaction, and it does not remove the ATM’s own usage fee.

Japan Post Bank states that for certain overseas-issued cards an ATM usage fee of ¥220 including tax per use may apply, and that your card issuer may charge additional fees (as of October 2026). Seven Bank says fees for cards issued overseas vary by card brand, and does not publish a single figure on its overseas-card pages (as of October 2026); the per-transaction charge is shown on the ATM before you confirm.

Many cards also carry a foreign transaction fee that applies to any non-home-currency purchase. If yours does, you pay it on the yen transaction as well — so the honest comparison is “merchant markup plus your card fee” against “your card fee alone”, not “fee” against “no fee”. Check your card’s own terms before the trip; that is the one number in this whole article you can look up in advance.

Japanese ATM practicalities worth knowing

Two operators cover most travellers’ needs, and their published limits differ.

Both operators note that a card bearing an accepted mark may still be declined, and Japan Post Bank points out that balance inquiries are not available for overseas cards. Seven Bank ATMs are also present at airports including New Chitose, Narita, Haneda, Chubu Centrair, Kansai, Fukuoka and Naha, which is where many travellers make their first withdrawal.

Frequently asked questions

Can I refuse to pay in my home currency in Japan?

Yes. Visa’s rules require a merchant, ATM acquirer or branch offering DCC to tell you that DCC is optional, to obtain your express agreement, and not to impose additional requirements on you to have the transaction processed in the local currency.

What if the cashier has already selected my home currency?

Ask for the transaction to be processed in yen. Visa’s rules prohibit language or procedures — pre-selecting the DCC option is the stated example — that could cause you to choose DCC by default, and for in-person transactions they require you to agree via a customer-facing screen or handheld device.

Is the ATM currency question the same as the DCC question?

At a Seven Bank ATM, yes. Its described Visa withdrawal flow has you choose the yen amount, then choose the currency used to calculate your billing amount. That second step is the DCC decision.

Does choosing yen mean I will not know the final cost right away?

Correct, and that is the trade-off. Seven Bank notes that with standard settlement the yen amount is settled at the ATM and the home-currency amount is converted and billed later, so the exact charge appears on your statement rather than on the ATM screen.

Which cards avoid conversion costs entirely in Japan?

None will suit every traveller, and this depends on terms set by your issuer rather than by anything in Japan. The controllable part is the merchant markup: declining DCC removes it, and your card’s published foreign transaction fee tells you what remains.

The bottom line

Dynamic currency conversion is the rare travel-money mistake you can fix with a single tap. Choose yen at the terminal, choose yen at the ATM, compare both totals online, and keep the receipt if you ever accept the conversion. The screen is legally obliged to show you the markup before you agree — reading it costs nothing.
