Anyone have a little input on the most cost efficient rail in Tokyo? I'm flying into Narita and staying in Shibuya. Will probably spend limited time in the hotel and do as much possible in the city. I'm just trying to decide what pass to purchase, one that hopefully includes a ride back to the airport.
Are you staying in Tokyo the whole trip? I bought a Japan Rail (JR) Pass before I went because I was going to other cities, and it included my train between Narita and Tokyo (N'EX train). The pass also includes the JR line within Tokyo, but it's probably not worth buying for you -- price-wise -- if you're staying in Tokyo the entire trip.
When returning to Narita, I actually took the bus (Airport Limousine) from my hotel (Shinjuku Hilton) directly back to Narita because my JR Pass had expired by then. The bus made sense for me price-wise and travel-wise since I would've had to first trek my way over to the Tokyo Central train station just to get on the train to Narita. You'll have the same issue in Shibuya. I'd check out the bus options for your hotel:

But they're all relatively easy to figure out and you'll just use whichever is most convenient to your location. When you get in the station, you look at the map to see what the cost is from your station to the next (160 yen or whatever) and put that amount in the machine to get your ticket. Cash only.
I'm jealous of your trip. Hope you have a great time.
P.S. If you do karaoke while you're there, it makes sense to buy a membership. I now carry a membership card for Karaoke Kan in Shinjuku.
