There are two options for buses out of Narita. The Airport Limousine Bus (counter in the main lobby). Limousine Buses leave hourly and tend to make stops at all the major hotels. The price is approximately ¥2500 – 3500 (depending on destination). The buses make stops at all the major hotels; if yours is not one of the scheduled stops, a good option is to take the bus to the hotel closest to where you’re staying and then to take a cab the rest of the way.
The Airport Shuttle to the Tokyo City Air Terminal (TCAT) also has a counter in the main lobby of Narita. While this bus departs more often, it doesn’t stop at the major hotels. You will need to utilize other transportation from TCAT to your hotel.
If you choose to arrive via taxi to your hotel, you might consider the bus for your trip back. Your hotel’s concierge can assist in making travel arrangements.
