This is a great tip that will save you time and money in Tokyo and is not that well known about as most people use the JR line to get from Narita into the city.

The Skyliner & Metro Pass, available at the entrance to the Skyliner train in T2, is in my opinion the most convenient and valuable pass available for visiting Tokyo for a couple of days. It allows you to ride the Skyliner connecting Narita Airport and central Tokyo upon arrival and then to use all of the Tokyo Metro lines as many times as you like for one or two consecutive days at a reduced cost.

If you haven’t been to Tokyo before, the Metro underground train system gives you the most flexibility due to your ability to get to many more places than when just using the JR pass or lines. All of the major tourist attractions including Tsukiji fish market, the Imperial Palace in Hibiya, Harajuku and Omotesando (shopping), Shinjuku and Shibuya (neon), Ueno and Asakusa (temples and history), Roppongi and Roppongi Hills are directly on Metro lines so it makes seeing these much easier.

The Skyliner train plus a 1-Day Tokyo Metro Pass costs 2,100 yen which is a saving of 530 yen or if staying a little longer then the Skyliner plus a Tokyo Metro 2-Day Pass costs 2,480 yen which is a saving of 860 yen. When you consider the JR Narita Express takes the same time and is about 3,000 yen, this is a great deal.
