The easiest way to get from Narita Airport to central Tokyo is by the Friendly Airport Limousine Bus. Most of you are probably wanting to take it to Shinjuku Station’s west exit but there are endless destination points to choose from including major Tokyo Hotels.
Terminal 1 has five tickets counters, while Terminal 2 has two tickets counters, all with helpful English speaking staff. Buses depart right outside of Narita aiport’s central exit every 20 minutes. The bus stop is on the ground level so no bags to haul up stairs or maneuver through escalators. You can roll your airport luggage cart through customs and right up to the bus luggage compartment. There are even some friendly staff attending to passengers, checking tickets, and making sure your gear is safely stored in the baggage compartment under the bus.
Ask for a window seat to get some great views of Tokyo bay and the urban sprawl of one of the most densely packed cities in the world.
A bus to Shinjuku will cost you about 3000 yen one way and take between 85 to 115 minutes depending on traffic. For current travel times, fares, departure and arrival options, check out their English site here
