This article provides an overview of the rules and regulations for bringing money into Japan. It discusses the limit on carrying cash, how to exchange money, what currency to bring, safety concerns, and tips for travelers. The Japanese government requires individuals entering or leaving Japan with more than 1 million yen in cash or traveler’s checks to declare it at customs upon arrival or departure from the country. Foreign currency can be exchanged at banks, post offices, authorized foreign exchange dealers, and some hotels throughout Japan. Credit cards are widely accepted throughout most major cities and tourist areas within Japan; however they may not always be accepted outside these areas so it is best practice for travelers to have both forms of payment available when traveling around Japan. Pickpocketing does occur occasionally so it is best practice not to carry large amounts of cash around with you while traveling in public places such as train stations or busy streets during peak hours.
