Japan is widely known for its easy-to-use and convenient public transport. Nonetheless, Tokyo is a HUGE city and maybe confusing at first.

Hint: Google/Apple/OpenStreet Maps are very good at leading you the right way. Most of Tokyo’s subway lines and stations offer free Wifi.

Travel to Tokyo

Tokyo is served by two international airports (Narita and Haneda) which have great connections to the city centre.

NOTE: Unless you choose to pay for each ride individually, you will probably need to purchase a public transport pass. It is often convenient to do this right away at the airport after arrival. (see also Subway Passes below)

After arriving in Japan by plane, you might want to first head towards one of the major train stations (Tokyo Station, Ueno Station, Shinjuku Station) and continue from there, depending where your hotel is located.

From Narita Airport

There are several options to get to central Tokyo from Narita Airport.

Here is a more detailed overview of the options: Transport to and from Narita Airport

From Haneda Airport

Haneda is located just south and a bit closer to the city centre.

  • The easiest connection is to take the Tokyo Monorail to central Tokyo (e.g. Tokyo Station or Ueno Station).
  • A taxi will cost somewhere between JPY 7,000 and JPY 10,000, depending on the exact destination.

Within Tokyo (Getting to Hitotsubashi Hall / NII)

NII’s main building is located very centrally, just north of the Imperial Palace with good access to various sightseeing spots, e.g., Ginza, Shinjuku, Roppongi, Akihabara, Asakusa and Tokyo Tower.

It is conveniently located in walking distance from several major subway lines. The closest subway stations are Jimbōcho Station and Takebashi Station. It is a 3–5 minute walk from either station.

  • If you arrive by Tokyo Metro Hanzomon Line / Toei Mita Line / Toei Shinjuku Line get off at Jimbocho and head towards Exit A9.
  • Should you come by the Toyko Metro Tozai Line, exit at ”TAKEBASHI” and head towards Exit 1b.

Subway passes

Japan has a very convenient prepaid card system (Pasmo / Suica) that can be bought at most subway stations and many other places (e.g. convenience stores). These cards can also be used to pay at many restaurants, convenience stores, vending machines, etc.

Tourists can, however, purchase cheaper 24/48/72 hour tickets. You will probably have to show your passport to prove your tourist status. More information here:
