Tokyo - Haneda Airport (HND)

The airport has three terminals partly build on reclaimed land and a landfill in the Tokyo Bay (one of the runways is build on top of the landfill so it may be you land basically on garbage). The two main domestic terminals, terminal 1 and 2, are located next to each other and connected by an underground walkway. The international terminal is on the other side of a runway and a free shuttle bus connects it to the domestic terminals.

Haneda is located 14 km south of Tokyo Station in the Tokyo Bay.

Tokyo Haneda has several public transport options for getting into central Tokyo. The Tokyo Monorail (JPY 500, every 4 minutes, trip time 13 minutes) has a station at all three terminals and the monorail will terminate at the Hamamatsucho station 17 km away from where you can easily connect to other trains. The airport also has train stations at each terminal for the Keikyu train which can also bring you to inner Tokyo. Both the monorail and Keikyu train in fact compete for the same passengers. Also shuttle buses run from the airport to various destinations in the region and to Narita Airport (1,5 hour for JPY 3500) but you can connect to Narita by train as well (JPY 2000).
Although the airport operates 24 hours most of the public transport option and most of the shops, especially in the international terminal close in the night. If you land after midnight you may not have another choice than using a taxi. There are plans to improve this situation though.
