Japanese bank <-> US credit card

Hi! I'm moving to Japan in a couple of weeks. I'm wondering if there is a good way to continue using my credit cards from US banks (e.g. chase/amex), while paying off the balance with funds from a Japanese bank?

My job will be paying my salary into a Japanese bank account. From some googling, it doesn't sound like there are any straightforward options, but wanted to ask around just in case.

Thanks!
