If your credit card is a dual-currency credit card, you can pay on foreign websites through the payment channels of VISA and MASTER. Beware of foreign phishing websites.

If you open an account in a domestic bank and the customer opens an account in a Japanese bank, Alipay does not support foreign exchange transfer and the other party cannot receive the money. You can use overseas remittance to directly convert the money into foreign currency and remit it to the other party's account, and then let the other party buy it.

If you and your customers both open accounts in China, you can pay them by domestic remittance, and ask them to bring them back to you after purchasing them abroad. Or through Alipay transaction, confirm the payment to the other party after receiving the goods.

Direct remittance is risky. Once the money is remitted, it cannot be withdrawn.
