Shibuya Station to Narita Aiirport

I would like to ask for directions from Shibuya station to Narita International airport. I will be staying in a hotel near the Shibuya station and was wondering how to get back to the airport the following day. Thanks!

The Narita Express stops at Shibuya. For other options, see Hyperdia.

Four railroad operators have Shibuya Stations, with tracks are above and under the ground in at least two separate buildings. And, there are many hotels are round them.
I recommended you would check in advance your route from the hotel to a gate of Shibuya Station of JR.

If you stay in Hotel Mets Shibuya, for example, you can directly get to New South Gate of Shibuya Station of JR, and the gate is very close to the platform for Tracks 3 and 4 used by "Narita Express" trans; so unless your plane departs too early in the morning, you can smoothly take a "Narita Express" train to NRT Terminal 2 / Terminal 1 and catch the plane.

Just walk into the station and buy a ticket for the Narita express from the ticket machine. Its about 3000 yen. You have to have a reserved seat on this train. Then just follow the signs to the Narita Express platform. Easy!!

cheapest way:
shibuya to nippori by JR yamanote line(outer) 28 min 200Y, change to(very easy change) nippori to narita airport on keisei main line limited express, 71 min and 1030Y.
