No, a Japanese PSN account can only be funded with a Japanese PSN card, one with a yen amount on it.
It's actually known as a PSN ID. http://www.us.playstation.com/PSN/mediago
PSN only accept Credit Card or Debit Card that belongs to the region in which the PSN account was created. If you have a US PSN account then you can use only US credit or debit card.This is because PSN does some background check called Address verification Check which is basically Sony checking with your card issuing bank about the address, if the address is from a different region then you will not be able to use that card for that account.Other alternative is to use PSN cards. If you are from a different region and you use a different region PSN account then the best option is to buy a PSN card online.More detail on this can be found at : http://invisibleknight.blogspot.com/2013/04/psn-cards-playstation-network-cards-how.html
