You can choose to run a JCB brand credit card when you go to Japan. JCB Credit Card is a card organization in Japan. There are many special merchants in Japan, and the discount is relatively high.

In addition to JCB credit cards, cardholders can also apply for VISA and MasterCard brand credit cards which are widely used abroad.

In addition, UnionPay credit cards are now available in some places in Japan, and sometimes there are cashback activities. But you'd better prepare a foreign currency card. If the bank card doesn't work, use a foreign currency card.
