I bought a magazine before bording in CKS Airport. In the last part of the magazine, it provides some traffic infomation in Tokyo, including the ways to go to Tokyo from Narita. I noticed that there is a new solution..... well, actually not "New", but "cheap" and "fast", which is the " N'EX special package for foreigners".
"N'EX" is the initial of " Narita Express", which is the express train from Narita Airport to Tokyo and Yokohama, but the tickets are very expensive. For example, an one way ticket from Narita Airport to Shinjuku costs 2900 yen.
The special package for foreigners includes an one way ticket and a "Suica" (valued 2000 yen, which is a prepaid card that you can use it in all the public transportation ) and just cost 3500 yen.
Ordinarily, if I bought the N'EX and the Suica separately, it would cost 2900 + 2000 = 4900, so I can save 1400 yen with the special package. Passengers who travel to Yokohama will save more with this package.
