Pay in Yen or Your Home Currency? Japanese Card Machines Explained

The short answer: When a Japanese terminal or ATM offers to charge you in your home currency instead of yen, that is dynamic currency conversion (DCC), and the exchange rate comes from the merchant's provider rather than from your card network. Choosing yen is normally the cheaper option. Both Visa and Mastercard require the choice to be yours and the markup to be shown before you decide.

This is a small decision that appears many times on a trip: at hotel checkout, at a department store counter, at a convenience-store ATM withdrawal. Each one is a two-second tap, and each one can quietly add a few percent to the bill. Unlike most travel money advice, this one is fully documented by the card networks themselves, so you can check the rules rather than guess.

The guidance below was checked on October 24, 2026. Fees and rates change; the structure of the decision does not.

What the screen is actually asking

A Japanese card terminal that supports DCC will show you the amount twice: once in yen, and once in the currency your card is billed in. It then asks which one you want the transaction processed in. The wording varies by terminal brand, but the two numbers side by side are the giveaway.

If you pick yen, your card network (Visa, Mastercard, JCB and so on) converts the amount using its own rate when the transaction settles, and your bank may add a foreign transaction fee on top. If you pick your home currency, the conversion happens at the terminal, using a rate chosen by the merchant's DCC provider — and your bank may still add its foreign transaction fee, because the transaction is still a foreign one.

That last point is the part most travellers miss. Choosing your home currency does not make the purchase domestic. It changes who sets the exchange rate, not where the card was used.

What the card networks require

Both major networks publish rules on this, and both are unusually direct about it.

Visa's traveller guidance states that "merchants and ATMs should give you a choice to accept or decline currency conversion and must not choose on your behalf," and that providers "should not use language or procedures such as different font size or color to influence your decision." Visa also lists what must appear on the screen and receipt: the amount in local and cardholder currency, both currency symbols, the exchange rate used, and any additional fees or markup assessed. If those details are missing, Visa's own recommendation is to "decline the currency conversion offer and report the incident to your card issuer." (Visa: Decoding Dynamic Currency Conversion)

Mastercard's 2025 merchant guide goes further into terminal design. Its DCC offer requirements state that no currency conversion method may be the default option, that the cardholder "must not be required or encouraged (i.e. 'steered') in any manner to use DCC," and that the offer must be presented in a clear and neutral manner. On consent, the guide is explicit: "If the cardholder does not explicitly choose to have the transaction completed in their billing currency, it must be processed in the local currency. … Automatic DCC is not permitted by Mastercard Standards." (Mastercard DCC Performance Guide, merchant version)

The same Mastercard guide bans a list of specific terminal behaviours, which doubles as a checklist of red flags to recognise in the wild:

Mastercard also requires that before you make your selection you be told your right to choose the currency, the amount in local currency, the amount in billing currency, the conversion rate to be applied, and any other fee that can be charged if you select DCC — for example commission or VAT.

None of this means DCC is fraud. It is a disclosed, permitted service. It just means the rules assume you will be given enough information to decline it, and that declining must not be made awkward.

A worked example on a ¥30,000 hotel bill

The markup on a DCC transaction is typically expressed as a percentage added to a wholesale rate, and the exact figure is set by the provider — which is precisely why the networks require it to be displayed. Rather than claim a universal number, work the arithmetic yourself with whatever percentage the screen shows you.

Suppose your hotel bill is ¥30,000, and the terminal shows both the yen amount and a home-currency amount. Take the home-currency figure, divide it by 30,000, and you have the effective rate you are being offered. Compare that with the mid-market rate on your phone. The gap is the cost of convenience.

The right-hand column is the one worth looking at. A single ¥300 difference is not worth thinking about; the same decision repeated across a trip is a restaurant meal or an extra shinkansen leg.

To make the comparison concrete at the counter, here is the arithmetic in one line: home-currency amount ÷ yen amount = your effective rate. If your phone says the mid-market rate is 150 yen to the dollar and the terminal is offering an effective 142, you are paying roughly 5% for the convenience.

ATMs: the same question, different screen

Cash withdrawals in Japan raise the identical choice, and the two networks most visitors use both document it.

Japan Post Bank's international ATM service page states that cards bearing VISA, PLUS, Mastercard, Maestro, Cirrus, JCB, China UnionPay and DISCOVER can withdraw at its ATMs, and that "when using certain cards issued abroad to withdraw cash (Japanese yen), you may finalize the settlement amount in the currency of the country where your card was issued." That sentence is the DCC offer. The same page notes an ATM usage fee of ¥220 (tax included) per use may apply to certain cards issued abroad, in addition to any fee your own bank charges. (Japan Post Bank: International ATM Service)

Seven Bank's international card page sets out the other half of the coverage picture: over 28,000 ATMs at 7-Eleven stores nationwide, plus machines at New Chitose, Narita, Haneda, Chubu Centrair, Kansai, Fukuoka and Naha airports, accepting VISA, PLUS, Mastercard, Maestro, Cirrus, UnionPay, American Express, JCB, Discover and Diners Club. It notes that some cards carrying these marks may still not be accepted. (Seven Bank: using international cards)

Japan Post Bank also publishes a single-transaction withdrawal limit of ¥50,000, and notes that balance inquiries are not available for foreign-issued cards. Plan larger withdrawals as multiple transactions — and remember each one may carry its own fee.

The decision tree at an ATM has one extra branch compared with a shop terminal, because there are two separate fees in play: the ATM operator's charge and your own bank's overseas withdrawal fee. Taking out larger amounts less often reduces the number of fixed fees. Taking out your home currency instead of yen adds a conversion markup to each one.

What to tap: the short version

1. Look for two amounts on the screen. One in yen, one in your currency.
2. Choose the yen amount. Every time, unless you have a specific reason not to.
3. If the screen does not show the rate and any markup, that is a disclosure failure under both networks' rules.
4. If you cannot find a way to choose yen, ask the staff to cancel and re-run the transaction.
5. Keep the receipt. The amount you were charged, and the currency, should both be printed on it.

If a transaction is processed in your home currency without you choosing it, Visa's guidance is to report the incident to your card issuer. That is a real remedy, not a formality — the issuer is the party with a contractual relationship to the acquiring bank.

Cards that charge a foreign transaction fee anyway

Avoiding DCC does not make a foreign purchase free. Many cards add a foreign transaction fee, commonly expressed as a percentage of the converted amount, and that fee applies whether or not you chose yen.

This matters for trip planning because the two costs stack differently depending on what you do:

Before the trip, look up your card's foreign transaction fee in its published fee schedule. If you hold more than one card, bring the one with the lower fee and treat the other as a backup. Travel-focused and some digital-bank cards advertise no foreign transaction fee; cards bundled with rewards programmes often do charge one. Neither is universally better — it depends on how much you expect to spend.

One practical note: a card with no foreign transaction fee removes the main reason anyone ever argues for DCC, which is budget certainty. If the conversion costs you nothing beyond the network rate, there is very little left to weigh.

Where you will meet this in Japan specifically

Japan has moved quickly toward card acceptance, which means the DCC prompt now appears in places it did not a few years ago.

Tax-free shopping is a separate matter and does not interact with this choice. If you qualify for the consumption tax exemption, that is handled by the shop's tax-free process regardless of which currency you settle in.

Contactless payments and wallet apps follow the same rules. If you tap a phone and the terminal offers a currency choice, the choice is still yours to make.

Cash is still part of the answer

Japan is no longer a cash-only country, but it is still a country where cash solves specific problems cleanly — and cash sidesteps the currency question entirely once it is in your pocket.

Small restaurants, older shops, shrine and temple offerings, coin lockers, some bus fares in rural areas, and market stalls still lean on cash. Carrying a modest reserve means you are never forced into a bad payment decision because the alternative is no payment at all.

The practical approach for most trips is a single larger ATM withdrawal early on, taken in yen, rather than a string of small ones. You pay the fixed ATM fee once instead of five times, and you still have card coverage for the large transactions where the DCC decision actually matters.

One caution worth stating plainly: withdrawing more cash than you will spend simply moves the conversion problem to the end of the trip, when you change leftover yen back at an airport rate. Estimate your cash-only spending honestly rather than generously.

A pre-trip checklist

Five minutes before you fly saves the guesswork at the counter.

1. Find your card's foreign transaction fee in its published schedule and write the number down.
2. Tell your bank you are travelling, if it still requires that.
3. Check whether your card is in the accepted-brand list of the ATM networks above.
4. Note your daily ATM withdrawal limit, and remember Japan Post Bank's ¥50,000 per-transaction cap.
5. Save your issuer's overseas contact number somewhere reachable without data.
6. Decide which card is your primary and which is the backup, and carry them separately.

Frequently asked questions

Is it ever right to choose my home currency?
Only if you genuinely need the exact billed amount locked in at that moment — for an expense claim with a strict deadline, for example. You are paying for that certainty, and the terminal is required to show you how much.

Does DCC affect the exchange rate I get on a refund?
A refund is processed as its own transaction, so the rate can differ from the original purchase. This is one more reason to keep receipts for anything you might return.

Will declining DCC cause the payment to fail?
No. Visa states explicitly that opting to accept or decline DCC "will not impact your ability to make purchases or withdraw cash internationally."

The staff member tapped the screen before I could.
Under Mastercard's standards, DCC must not be selected in the cardholder's absence or without consent. Ask for the transaction to be voided and redone, and keep the receipt either way.

Does this apply to online bookings made from abroad?
Some booking sites offer a currency choice at checkout. The same logic applies: the site's conversion rate is not your card network's rate. Compare before you confirm.

What about IC cards like Suica and Pasmo?
Topping up with cash avoids the question entirely. Topping up with a foreign card may present the same prompt.

Summary

The currency prompt on a Japanese card terminal is not a trick question, but it is not a neutral one either. The default correct answer is yen, because that keeps the conversion with your card network instead of adding a second, merchant-set rate on top. Both Visa and Mastercard require that the choice be yours, that the rate and any markup be shown before you decide, and that declining be as easy as accepting.

Before you fly, check your card's foreign transaction fee so you know what the yen route actually costs you. On the ground, look for two numbers, pick the yen one, and keep the receipt. Repeated across a two-week trip, that single habit is worth more than most of the money-saving tactics people spend real time on.
