I realized from the pass week of experience, banks in Japan is very
stupid in handling international money transactions. Can someone tell
me how i can send money from US to JP to a existing credit card
account to pay off the credit card bills? The credit card company is
quite big in JP but the branches in US don't handle any "normal"
customers, only businesses. So I am trying to find out the best
cheapest safest way to accomplish this.

So far i have try wiring money from BofA to JP bank but Japanese
credit card company don't know the swift number(routing number) very
stupid. So what else can i do? Any help would be appricated!!! Thanks
