Tokyo has two large airports: Narita for international flights, and Haneda for (mostly) domestic flights.
Narita Airport
Tokyo’s main international gateway is Narita Airport (成田空港) (IATA: NRT) , located in the town of Narita nearly 70 kilometers northeast of Tokyo and covered in a separate article. A brief summary of options for getting there and away:
Easiest: Limousine bus direct to major hotels, ~120 minutes (subject to traffic), ¥3000
Fastest: Narita Express to Tokyo Station, Shibuya, Shinjuku, Yokohama, 55 minutes, ¥2940 (Japan Rail Pass valid)
Cheapest: Keisei Limited Express train to Nippori/Ueno, ~80 minutes, ¥1000
Most expensive: Taxi to the city, more than ¥30,000
Haneda Airport
Haneda Airport (羽田空港 IATA: HND) , officially known as Tokyo International Airport, in Ota is the busiest airport in all Asia despite being (almost) entirely limited to domestic traffic. Terminal 1 houses the JAL group including Skymark and Skynet, while Terminal 2 is home to ANA and affiliate Air Do. Shuttle services to Hong Kong, Seoul-Gimpo and Shanghai-Hongqiao use the small separate International Terminal, which is connected to the main domestic terminals by a free shuttle bus that runs every 5 minutes.
The easiest and most scenic way from Haneda to the city is the Tokyo Monorail [4] with a station in each terminal running to Hamamatsucho (16 min, ¥470), from where you can connect to almost anywhere in Tokyo on the JR Yamanote line. The other, slightly cheaper alternative is the private Keikyu (京急) line, which has a single station between the terminals and runs to Shinagawa (19 min, ¥400) and Yokohama (27 min, ¥470). Keikyu also runs trains to Haneda from the Toei Asakusa subway line, and even a few direct services to Narita. Note that there is no JR service to the airport, and the “Airport Terminal 2″ station that pops up in some route search engines is located in Narita, not Haneda!
Expect to pay anywhere from ¥4,000 to ¥10,000 for a taxi to central Tokyo.
Chōfu Airfield
Chōfu Airfield (調布飛行場 Chōfu hikōjō) serves only some turboprop flights to the Izu Islands south of Tokyo. The nearest railway station is Nishi-Chōfu on the Keiō Line, a 15-minute walk away. Alternatively, you can take a bus from Chofu or Mitaka stations.
