Tokyo is serviced by two major airports, Tokyo international at Haneda
and Narita International which was once known as New Tokyo International
Airport. Narita was built as a replacement for the older Tokyo
International Airport and as such Narita handles mostly international
flights while Tokyo now mainly handles domestic flights. Both airports
are a fair way out of central Tokyo and it would be well advised to
catch either a train of shuttle bus into the city rather than a taxi.
Tokyo Airport at Haneda is served by the Keikyu Line and Tokyo Monorail
while Narita Airport is served by the Keisei line and JR Narita Line.
You can get from Haneda to Narita by using the Keikyu line and then
transferring to the Keisei Line at Shinagawa.
If you are traveling from another city in Japan one of the best ways to
get to Tokyo is by Japans famous bullet trains known as the
Shinkansen. Bullet trains are fast and much like
traveling on an airliner, services to all major cities can leave
sometimes every 15 minuets. Because the Shinkansen service departs from
Tokyo Station the service is ideal for tourists staying in the area,
most people find it just as fast as traveling by air but without the
hassle.
Finally as Tokyo is a major sea port several cruise ships operate in and
out of Tokyo's port. The Japanese love to travel and their are plenty
ships that run cruises around the region.
