Getting from Narita to Shin-Okubo station

Hey everyone,
I need some help figuring out how to get to my hotel. I've already kind of tried to think of what to do. I want to take the airport limousine bus (I'll be in no mood to tackle the trains) but it doesn't go to my hotel, the closest it will get me is Shinjuku station. From what I gather, Shin-Okubo station (a very short walk from my hotel) is one stop away on the Yamanote line, problem is I don't know where to enter the station at or where I'll be going once I'm inside (we don't have a big train system in Seattle).

Any help is much appreciated, let me know if you know of a better way to get to my hotel. All I know is that I'll be able to get there once I get to Shin-Okubo station. Thanks.

why not take a cab from Shinjuku?

You get off at Shinjuku, enter the station through any gate that says JR Shinjuku, ride on train at track number 15 (green colour) and you're in Shin-Okubo within 2 minutes. Shin-Okubo has only one exit so you won't get lost.

Regular train(rapid/Not NEX or Skyliner as LtdExp) cheaper than bus
same one transfer but just one ticket(or Suica/PASMO) from NRT.

Fastest way by NEX until JR Shinjuku
then change platform of JR Yamanote line
not need ticket gate out.
