Haneda is the most convenient airport in Tokyo.
It now offers international and domestic flights.
It is one of the busiest airports in Asia, but it doesn’t feel that way.
It is also the primary base of Japan Airlines (JAL, terminal 1) and All Nippon Airways (ANA, terminal 2).
It is cheap and easy to take trains or the monorail into central Tokyo from Haneda.
Best of all, on a clear day you can see Mt. Fuji from the windows.
