Currency in Japan
Japan’s official currency is the Japanese Yen (JPY).
Banknotes are commonly issued in different denominations, and coins are frequently used for smaller purchases, vending machines, and public transport in some situations.
It’s a good idea to familiarize yourself with the yen before your trip so you can quickly estimate prices while shopping or dining.
Cash vs. Card
Japan has become increasingly cashless in recent years, especially in larger cities. However, cash is still useful, particularly at smaller businesses, local markets, rural attractions, and some traditional restaurants.
Credit and Debit Cards
Cards are widely accepted at:
- Hotels
- Department Stores
- Major Restaurants
- Large Retail Chains
- Many Attractions
Carry Some Cash
You may still need cash for:
- Small Local Restaurants
- Temples and Shrines
- Street Food Vendors
- Rural Shops
- Some Buses or Taxis
A combination of card and cash is usually the most practical approach.
Using ATMs
ATMs are easy to find throughout Japan. You’ll commonly find them at:
- Convenience Stores
- Banks
- Airports
- Shopping Centers
Before Traveling Check:
- International withdrawal fees
- Daily withdrawal limits

Currency Exchange
Travelers have several options for exchanging money:
- Exchange Before Departure
- Airport Exchange Counters
- Banks
- Licensed Exchange Offices
Compare exchange rates and fees before converting large amounts of money.
Mobile Payments
Japan supports several mobile payment systems, though international travelers often continue using contactless bank cards or digital wallets where accepted.
If you plan to rely on your smartphone for payments, confirm compatibility with your device and payment provider before your trip.
Is Tipping Expected?
Unlike many countries, tipping is generally not part of Japanese culture. Restaurants, taxis, hotels, and other service providers typically include excellent service as part of the experience. Leaving extra money may cause confusion or be politely declined.
