Tokyo is well-connected by airways to the rest of the world, so plenty of airlines across the world, including Asia and India also connect to Narita Airport. These include Air India, Emirates, Jet Airways, Lufthansa and Etihad. Flights to Tokyo can be boarded from any major Indian city.
Tokyo has well-established connections to every major city around the world, and every major airline lands at Narita Airport, the most important airport in Tokyo.
From Narita Airport, one can use the road to travel to Tokyo.
Tokyo is the centre of railways and the subway in Japan, with connections to every single city in Japan. The subway and the railways can be used with a rechargeable card, but a map is a must as some of the railways and subway lines are slightly difficult to navigate.
Tokyo also has a good bus service, for which rechargeable cards are also available. There are inter-city buses, as well as intra-city bus services. Most intra-city buses require small change, so it is advisable to carry coins and JPY 1000 notes.
Waterways are only applicable from island-to-island in Japan, so from Kyuushu one can take the ferry to Honshu to visit Tokyo.
