Do the stores in an airport in Japan accept US Dollars?

Question:

I'm going on vacation during the summer, and one of the stops during the flight is Tokyo, Japan. I'm going to be there for about 3 hours and wanted to go to the stores. I was wondering if the stores in the airport accept US Dollars. If not, is there a place I can exchange Dollars for Yen within the airport?

P.S. The airport is Tokyo Narita Airport.

Answer:

No. You must use yen. Not all restaurants or stores at Narita accept credit cards either.

Yes, you can exchange money at the airport. You won't get a very good exchange rate and there may be minimum exchange amounts but it is possible. I'd go to your local bank a few weeks before you leave and get some yen.
