Aside from an excuse to show the awesome new E259 series N’EX trains, the answer is yup. Most people don’t realise that the Japan Rail Pass opens up direct, high speed links to many Japanese destinations direct from Narita Airport.
The average fare for the service is around ¥3000-¥5000 return with a N’EX ticket. Of course, it’s totally free if you have a Japan Rail Pass!
