Credit cards are safe. For overseas consumption, you can use them directly according to the card organization logo. UnionPay, VISA, MasterCard, etc. can be used if they are available locally. Credit cards are generally used, and third-party payment platforms such as Alipay and WeChat are now very popular in big cities in Japan such as Tokyo and Osaka. In addition, many banks such as CCB Long Card will offer cash back for overseas consumption. You can get 8% cash back when you use UnionPay and VISA credit cards, and you can get 10% cash back when you use JCB logo, so it is still better to use a credit card. Not bad.
