First visit to Japan

How to get to 2-14-4, Odai, Adachi-ku, Tokyo. 120-0046, from Narita? I'm planning to go to Japan this December and apparently it's going to be my first visit there. I'm going with a group of 14 people. Do you guys have any recommendations on what transportation to use to get there? (I would prefer avoiding taxis as they cost a lot).

Just glancing at a map, but you can take the Keisei Skyliner or limited express from Narita to Nippori, then transfer to the Nippori-Toneri Liner and get off at Adachi-odai, which seems to be the closest station to your address.
I'm not familiar with the area or anything, but someone else will probably be along in a little bit to give even better/more detailed advice.

Try this address in google maps:

Seems to be quite straightforward. Train to Nippori station , change train and ride to Adachi Odai station and then walk.

There is also a bus getting you closer but with 14 people plus luggage I wouldnft take the bus as you are going to essentially capture it.

Enjoy your trip to Japan!

On the other hand the Toneri Liner gets very full at certain times of day. I used to live at Kumanomae and for such a small train it really can be a nightmare. Itfs the most straightforward way to get where you are going but if I had a choice I would not want to take 14 people plus luggage on there.
