When you arrive at Tokyo International Airport (Haneda Airport), you maybe worry about the transportation to your destination.
If you come to Western Tokyo Tama area, it would be easier to come by airport bus as there are a lot of destinations to Tama area such as Tachikawa, Hachioji, Tama center, Chofu, Fuchu, etc.
Hope that your first travel from Haneda airport in Japan would be the perfect start with the airport bus trip.
