Akin to the Heathrow Express, just jump on the Nippori Express and 30 min later you are at Narita. First, Terminal 2, 3. Then, for International Flights, Terminal 1. It costs about $ 20 bucks, which is very good considering a taxi is $ 150+ from downtown Tokyo. Seats recline, are firm yet comfy. Plenty of space for luggage and its spotlessly clean, like everything else in Japan. Upside to a taxi other than price is, it drops you right in the Terminal. Up 4 escalators about 30 yds from the track and you are at your checkin counter merely 2 min from getting off a rather quiet, lovely train ride from downtown Tokyo. If you are headed to Narita from Tokyo, this is the way to go.
