How to use this Japan credit card fee calculator

Enter the yen purchase amount, an estimated JPY per USD exchange rate, and your card's foreign transaction fee. The calculator estimates the U.S. dollar charge and compares paying in yen with merchant-provided U.S. dollar conversion.

Should I pay in JPY or USD in Japan?

When a terminal asks whether to pay in Japanese yen or U.S. dollars, paying in yen is often cheaper. Merchant U.S. dollar conversion can include a markup before your card issuer sees the transaction.

What fees should travelers check?

Check whether the card has a foreign transaction fee, whether the purchase is charged in local currency, and whether the merchant is offering its own conversion. For ATM cash advances, separate ATM, cash advance, and interest charges may apply.
