Terms: 30

A

ATM operator fee: An ATM operator fee is a charge made by the company that owns an ATM for using its machine. It is separate from any fee charged by your own bank, and it may or may not be shown on screen before you confirm the withdrawal, so look at the confirmation screen carefully and cancel if the fee or currency is unclear. One withdrawal can carry several layers of cost, including the operator fee, your bank's fee, a foreign transaction fee and the exchange margin. See also: foreign transaction fee, daily withdrawal limit, and the guide ATMs and Fees in Japan.

B

Bank of Japan: The Bank of Japan is Japan's central bank. It describes itself as a juridical person established under the Bank of Japan Act, and its objectives include issuing banknotes, carrying out currency and monetary control, and ensuring smooth settlement of funds among banks; the Act states that monetary control shall be aimed at achieving price stability. It publishes English information on the yen and on its policies. For the price you will actually pay in a shop or at an ATM, your provider's rate is what counts. See also: yen, exchange rate, and the guide Using a Yen Rate Tool and Rate Alerts Wisely.

C

Cash advance: A cash advance is a cash withdrawal made using a credit card. Many issuers treat it differently from a purchase, with a separate fee and interest that may start accruing immediately rather than after a grace period, and it may earn no rewards. This is why many travelers use a debit card for cash and keep the credit card for purchases. The terms are set by your issuer, so check your cardholder agreement before relying on a credit card at a Japanese ATM. See also: foreign transaction fee, ATM operator fee, and the guide ATMs and Fees in Japan.
Consumption tax: Consumption tax is Japan's tax on many goods and services, similar in purpose to a sales tax. Prices may be shown with or without it, depending on the shop, so check the displayed price and the receipt. It is the tax involved in tax-free shopping for eligible visitors, whose rules are set by the authorities and can change. This glossary deliberately gives no rates, since figures are the details most likely to be revised; see the National Tax Agency for current information. See also: tax-free shopping, National Tax Agency, and the guide Tax-Free Shopping in Japan.
Contactless payment: Contactless payment means paying by tapping a card or phone on a reader instead of inserting the card. Support varies by terminal, card and country, and some foreign cards can have trouble with certain terminals, so a failed tap does not always mean your card is broken. Ask your issuer before you travel whether your card supports contactless payments abroad and whether you should expect to use a PIN, and test a phone wallet at home before you rely on it. See also: PIN, IC card, and the guide Cash vs Card in Japan.
Currency exchange counter: A currency exchange counter is a booth or desk, often at an airport or in a city center, where you swap one currency for another. It is easy to understand and convenient for a small amount of yen on arrival, but the cost is usually hidden in the rate rather than in a visible charge. Before you hand over money, ask what exact amount of yen you will receive, whether there are any fees on top, and whether that figure is final. See also: spread, margin, leftover cash, and the guide How to Exchange Yen.

D

Daily withdrawal limit: A daily withdrawal limit is the maximum cash you can take out in a day, set by your bank, the card network or the machine. It can cause a withdrawal to fail even when your balance is sufficient, so a declined attempt is not always a problem with your account. Limits can differ between machines and cards, and they are separate from per-transaction limits. Check your bank's limit before traveling and, if it is low, ask whether it can be changed. See also: ATM operator fee, cash advance, and the guide ATMs and Fees in Japan.
DCC: DCC is short for dynamic currency conversion, the offer to pay in your home currency instead of the local one. When a terminal or ATM in Japan asks which currency to pay in, choosing the local currency, yen, usually avoids it and lets your card network and issuer handle the conversion under the terms you agreed to. A quick check is to compare the dollar total on the screen with the yen price converted at the reference rate, plus your card's own fee if any. See also: dynamic currency conversion, cash advance, and the guide Avoiding Currency Conversion Traps.
Dynamic currency conversion: Dynamic currency conversion is a service at card terminals, ATMs and online checkouts that charges you in your home currency instead of the local one. The merchant, ATM operator or their payment provider sets the rate, and it can be less favorable than the rate your card network or issuer would apply if you paid in yen. The prompt may present the dollar total as the neutral choice. In most cases, choosing yen is the safer option. See also: DCC, foreign transaction fee, and the guide Avoiding Currency Conversion Traps.

E

Exchange rate: An exchange rate is the price of one currency expressed in another. For yen and dollars it tells you how many yen one dollar is worth at a given moment, and it changes continually while markets trade. A rate on a converter is a reference point, while the rate a provider gives you includes its own margin or fee. To judge an offer, compare the exact yen you would receive with what the same dollars would buy at the reference rate. See also: mid-market rate, spread, margin, and the guide Mid-Market Rate vs the Rate You Actually Get.

F

Foreign transaction fee: A foreign transaction fee is a charge some card issuers add to purchases or withdrawals made in another currency or processed abroad, often as a percentage of the amount. Not all cards charge it, and the figure differs by issuer and product, so check your own cardholder agreement or ask your issuer before you travel. It is separate from any margin in the exchange rate and from an ATM operator fee. Knowing which of your cards charges the least helps you choose which one to use at a shop in Japan. See also: ATM operator fee, cash advance, and the guide ATMs and Fees in Japan.

I

IC card: An IC card is a rechargeable contactless card used mainly for public transport in Japan and, in some places, for small purchases at shops and vending machines that show the accepted logo. You load value, tap in and out, and the fare is deducted automatically. Rules for buying, loading and refunding cards change by operator, so check with the issuer. Loading one with a foreign card may count as a foreign currency purchase with your issuer's fees. See also: Suica, Pasmo, and the guide IC Cards in Japan.
Interbank rate: The interbank rate is the rate at which banks trade currencies with each other in the wholesale market. People often use the term loosely as a synonym for the mid-market rate, and the two are closely related. Customers at exchange counters, ATMs and card terminals do not usually receive it, because each provider adds costs and profit to the price. It is still useful as a yardstick: the further an offer sits from the interbank level, the more the conversion costs you. See also: mid-market rate, margin, spread, and the guide Mid-Market Rate vs the Rate You Actually Get.

J

Japan Tourism Agency: The Japan Tourism Agency is a Japanese government agency responsible for tourism policy. Its materials are a source of official, visitor-related information, including policy on topics such as tax-free shopping, where it works alongside the National Tax Agency and the Japan National Tourism Organization. Use it for official background rather than for shop-by-shop procedures, which stores explain themselves. Rules and policies change, so look at its current pages before you travel. See also: JNTO, National Tax Agency, and the guide Tax-Free Shopping in Japan.
JNTO: JNTO is the Japan National Tourism Organization, which provides visitor information about traveling in Japan, including practical topics such as transport passes, payments and shopping. It is the source this site cites for the planned change to Japan's tourist tax-free system on 1 November 2026. Information for visitors changes, so treat its current pages as the reference and check them close to your departure. It does not replace your bank or card issuer for questions about your own accounts. See also: Japan Tourism Agency, tax-free shopping, and the guide Travel Money Tips for Japan.
JPY: JPY is the three-letter ISO currency code for the Japanese yen. You will see it on converters, bank statements, card receipts and exchange screens, and it is the first half of the pair written JPY/USD or USD/JPY. A statement that shows a charge in JPY tells you the transaction was made in yen, which is normally the setting you want at a terminal abroad. Check the direction of a pair before you read a converter, because yen to dollars and dollars to yen are different questions. See also: USD, yen, dynamic currency conversion.

L

Leftover cash: Leftover cash is the foreign banknotes and coins remaining at the end of a trip. Converting them back usually means paying the spread again, and some providers do not accept coins at all, so many travelers try to spend coins before leaving or keep the notes for a future visit. Order or withdraw only what you expect to need, and plan to spend down balances on IC cards and travel cards toward the end of the trip. See also: spread, travel money card, IC card, and the guide How to Exchange Yen.

M

Margin: A margin is an amount a provider adds to the wholesale exchange rate before offering it to you. It is often not shown as a separate fee, which makes it easy to overlook: a provider can advertise no commission and still give a rate that costs more than a competitor charging a clear, small fee. You can measure it by comparing the yen you are offered with the amount the reference rate would give, and the shortfall is the cost. See also: spread, foreign transaction fee, and the guide Mid-Market Rate vs the Rate You Actually Get.
Mid-market rate: The mid-market rate is the midpoint between the buy and sell prices of a currency pair in the wholesale market. It is a reference point and a neutral benchmark for judging offers, but ordinary customers usually do not receive it exactly, because providers add a margin or fee. This site's converter uses the European Central Bank's reference rate, which is close to it. A practical test is to multiply your amount by the reference rate and compare the result with the yen you are actually offered. See also: interbank rate, spread, margin, and the guide Mid-Market Rate vs the Rate You Actually Get.
Multi-currency account: A multi-currency account is an account that can hold balances in several currencies and convert between them, usually through an app. Features, fees and the way the exchange rate is set depend on the provider, so read the fee table and the conditions before you load money. Check also how your money is protected and what happens to a balance you do not spend. It can suit a traveler who wants to convert in stages, but it is one option among several. See also: travel money card, spread, and the guide How to Exchange Yen.

N

National Tax Agency: The National Tax Agency is the national authority responsible for taxes in Japan, including consumption tax. It publishes English information on the tax exemption system for non-resident visitors and on related procedures. Because the rules for visitors have been revised in the past and may be revised again, its current pages are the authority, and an older blog post or an article, including this glossary, is only a starting point. Confirm anything that matters with the agency or the store. See also: consumption tax, tax-free shopping, and the guide Tax-Free Shopping in Japan.

P

Pasmo: Pasmo is an IC card used mainly on transit in the Tokyo area, and it works much like Suica for trains, subways and buses. Like other IC cards, its terms for visitors can change, including how it is bought, how it is loaded and whether it can be refunded, so check with the operator. The stored value is in yen, so loading it with a foreign card is a foreign currency purchase with your issuer's terms. See also: Suica, IC card, and the guide IC Cards in Japan.
PIN: A PIN is a personal identification number used to authorize card transactions or withdrawals. Know the PIN for each card before you travel, because some terminals and machines prefer a PIN, and a card whose PIN you rarely use is a common cause of a declined withdrawal. Some cards require a particular PIN length or format, so confirm this with your issuer. Shield the keypad when you enter it, and avoid repeated wrong attempts, which can block the card. See also: contactless payment, daily withdrawal limit, and the guide ATMs and Fees in Japan.

R

Rate alert: A rate alert is a notification sent when an exchange rate reaches a level you choose. Some banks and card apps offer them, while this site does not send alerts. An alert informs you but does not lock in a rate or make a trade, and it cannot tell you whether the rate will rise or fall next. Because you choose the level, it reflects your preferences, not a market signal. The rate you are offered will still include a provider's margin, so check the real figure. See also: mid-market rate, and the guide Using a Yen Rate Tool and Rate Alerts Wisely.

S

Spread: The spread is the gap between the price at which a provider will buy a currency and the price at which it will sell it. Crossing the spread is one of the main ways exchange costs arise, and you cross it again when you convert leftover money back, which is why many travelers exchange only what they expect to need. The midpoint of the spread is roughly the mid-market rate. At a counter you may see two rates for the same currency, a buy rate and a sell rate. See also: margin, mid-market rate, leftover cash, and the guide How to Exchange Yen.
Suica: Suica is a well-known IC card used in the Tokyo area and accepted in many other regions of Japan, mainly for trains, subways and buses and in some shops. Availability for visitors, phone versions and refund rules differ and have changed over time, so check the issuing operator for current details before you rely on one. The balance is held in yen, and any leftover value is not converted back automatically, so load modest amounts at a time. See also: Pasmo, IC card, and the guide IC Cards in Japan.

T

Tax-free shopping: Tax-free shopping is a system for eligible short-term visitors to Japan that has allowed certain goods to be bought without Japanese consumption tax at the point of sale, at participating stores and with documents such as a passport. According to the Japan National Tourism Organization, Japan is changing the system on 1 November 2026 to a refund when you leave the country. Conditions and goods categories change, so verify them with the official JNTO and National Tax Agency pages or the store. See also: consumption tax, JNTO, and the guide Tax-Free Shopping in Japan.
Travel money card: A travel money card is a prepaid or multi-currency card that lets you hold or convert foreign currency, often through an app. Some travelers use one to convert in advance and then spend yen from the balance. Terms, fees and protections vary: compare how the conversion rate is set, whether there are fees for loading, converting, withdrawing or inactivity, what happens to leftover balances, and how the product is regulated, because some are not bank accounts. See also: multi-currency account, leftover cash, and the guide How to Exchange Yen.

U

USD: USD is the three-letter ISO currency code for the United States dollar. It is paired with JPY in a yen to dollar conversion and appears on statements, converters and exchange screens. If a terminal in Japan offers to charge you in USD, that is dynamic currency conversion, where the merchant or its provider sets the rate, and choosing yen instead usually lets your own card network and issuer convert under the terms you agreed. See also: JPY, exchange rate, dynamic currency conversion, and the guide Avoiding Currency Conversion Traps.

Y

Yen: The yen is the official currency of Japan, written with the symbol ¥ and the code JPY. Everyday prices are usually quoted in whole yen because fractions are rarely used, so a yen amount often looks like a large number to someone used to dollars. When you see a price in yen, a converter turns it into a rough dollar value at a reference rate, while the amount your card is actually charged depends on your issuer's rate and fees. See also: JPY, USD, exchange rate, Bank of Japan, and the guide How to Exchange Yen.
