The currency of Japan is yen. Currencies other than this will not be accepted for payment anywhere in Japan other than major international airports. While cashless payment methods are becoming increasingly common in Japan, many small retail stores and regional areas only accept cash, so please be sure to carry some with you just in case.
Common forms of currency in Japan are 1 yen, 5 yen, 10 yen, 50 yen, 100 yen, and 500 yen coins and 1,000 yen, 2,000 yen, 5,000 yen, and 10,000 yen bills. While 2,000 yen bills exist, they are not widely circulated.(Current as of 2023)
Souvenirs and other items purchased by foreign visitors to Japan who have been in the country less than six months are eligible for tax exemption if certain conditions are met. For “general goods” such as home appliances, clothing, watches, jewelry, etc., the total value of items purchased in one day at the same store must be at least 5,000 yen (excluding tax) to qualify for tax exemption. In regards to consumable items including food, beverages, medicines, cosmetics, etc., the total value of items purchased at the same store in one day must be between 5,000 yen and 500,000 yen (excluding tax respectively), packaged in a specified manner, and not used in Japan.
Foreign currencies are not accepted in most places in Japan, so you will need to exchange money into yen. There are currency exchange offices at all major airports, so you can exchange money upon arrival in Japan. You can also exchange money at major banks and some hotels. In most cases, bank counters are open from 9:00 a.m. to 3:00 p.m. on weekdays. In recent years, Japan has become increasingly cashless, but cash is still the only accepted form of payment in many places, so it is a good idea to keep cash on hand.
ATMs are available at banks and convenience stores and may accept credit and debit cards issued overseas. Convenience stores are easily found in urban areas and many are open 24/7, making them convenient when you suddenly find yourself in need of cash. ATM fees vary depending on the time and day of the week.
Although cashless payment services are becoming increasingly popular in Japan, mobile payment services from overseas are not available in many places. However, many stores and facilities do accept international brand credit cards. In addition, IC cards for foreign visitors to Japan can be repeatedly recharged and used in many stores, convenience stores, restaurants, and public transport.
Tipping is not customary in Japan however sometimes a 10 or 15% gratuity will be added to the service fee of hotels and restaurants.
