Personally, I suggest going to China Bank, which is the most professional foreign exchange bank. The remitter takes his ID card to the bank counter to fill in the remittance application (in English, it is best to bring someone who can write English for him. This kind of international remittance costs a lot and arrives slowly, so it is generally not allowed for bank staff to fill it in). Take RMB and the bank will change it into Japanese yen for you.

The information you need to provide

Name of Japanese receiving bank (accurate to sub-branches, such as Mitsubishi Bank Tokyo Sub-branch)

Address of receiving bank

Swift code of the receiving bank

Payee Name

Payee address

All the above information should be written in English capital letters. You can go to the bank or just go to the bank.
