Currency in Japan is the "yen." You can obtain yen at currency exchange desks at major airports around the world, Haneda Airport, Narita Airport and currency exchange shops in Tokyo and Yokohama. Exchange at the airport is recommended for your convenience. Most foreign currencies can be exchanged at banks and hotels where you stay. However, we highly recommend purchasing a certain amount of cash in Yen or U.S. dollars before leaving your home countries. A passport may be required for currency exchange services.

Credit Card

Most hotels, major department stores and restaurants accept VISA, Master, JCB, Amex and Diners. However, small shops like station kiosks, convenience stores, vending machines and train tickets for short distances do not accept credit cards. It is advisable to bring a certain amount of cash.


Many automatic teller machines (ATMs) in Japan do not accept credit, debit and ATM cards which are issued outside of Japan. The big exception is the ATMs found at the post offices and 7-Eleven convenience stores. (7-Eleven ATMs are also available at international airports and in major railway stations.) These ATMs allow you to withdraw cash using credit and debit cards issued outside of Japan, including Visa, Plus, Mastercard, Maestro, Cirrus, American Express and JCB cards and provide an English user menu. Recently, some major Japanese banks have also started to offer ATM withdrawals for international cards at certain branches. Look for the English information beside the ATM.
