How come you think you can open only one currency? You may have several currency in the account and I do (USD, EUR, JPY, CAD, GBP). For each currency you can register several banks but practically there are limitations. You need to be resident same as the bank or your citizenship is same location as the bank. They should match with IDs.

For banking system these protocol are used (as far as I realised)
USD, CAD, GBP : SWIFT (or manual OP in recent congestion?)
JPY : Japanese Domestic (Zengin)
EUR : SEPA or SWIFT(if necessary)

You won't be able to transfer USD via Japanese Domestic Transfer. You just need to open JPY bank account and just need to add JPY from the settings and register the bank.
