My family and I are scheduled to arrive at 9:00 pm in NRT, and we are staying in a small ryokan in Narita town. As far as I can tell, the trains stop running at around 10:00, and in any case the ryokan is a bit far to walk from the station with bags. So we are thinking of just taking a taxi from the airport. The question is, how much will this cost us? The fixed rate chart only lists destinations in Tokyo.

The other questions are whether we will have a hard time finding a taxi at that hour - I doubt it, but you never know - and whether taxi drivers accept credit cards.
