okkyu trains are cheaper, but Airport Limousines are much more frequent. The journey to most points in central Tokyo takes 90 minutes or so, but watch out in rush hour (especially on the way to the airport) as there may be traffic jams.
The Airport Limousine buses make three pickup stops (Terminal 1 North Wing, Terminal 1 South Wing, Terminal 2) and two dropoff stops (Terminal 1 and Terminal 2).
By taxi
A taxi to central Tokyo is extremely expensive, on the order of �30000 if you hail one directly by yourself (equivalent to a few nights stay in the average Tokyo hotel), and you are more likely to get stuck in a traffic jam than save any time. Flat fare taxi cabs to Tokyo go for around �17000-19000 from special taxi ranks, but even so, if you're in a hurry, it's generally much faster and cheaper to take the Narita Express or the Skyliner, and change to a taxi upon arriving in Tokyo or Ueno. If you're not in a hurry, consider the airport limousine bus
