Tokyo, as the center of the Greater Tokyo Area, is Japan's largest domestic and international hub for rail, ground, and air transportation. Public transportation within Tokyo is dominated by an extensive network of clean and efficient[40] trains and subways run by a variety of operators, with buses, monorails and trams playing a secondary feeder role.
Within Ōta, one of the 23 special wards, Tokyo International Airport ("Haneda") offers mainly domestic flights. Outside Tokyo, Narita International Airport, in Chiba Prefecture, is the major gateway for international travelers to Japan. All Nippon, Air Japan and Delta Air Lines have a hub at the airport.
Various islands governed by Tokyo have their own airports. Hachijōjima (Hachijojima Airport), Miyakejima (Miyakejima Airport), and Izu Ōshima (Oshima Airport) have service to Tokyo International and other airports.
Rail is the primary mode of transportation in Tokyo, which has the most extensive urban railway network in the world and an equally extensive network of surface lines. JR East operates Tokyo's largest railway network, including the Yamanote Line loop that circles the center of downtown Tokyo. Two organizations operate the subway network: the private Tokyo Metro and the governmental Tokyo Metropolitan Bureau of Transportation. The metropolitan government and private carriers operate bus routes. Local, regional, and national services are available, with major terminals at the giant railroad stations, including Tokyo and Shinjuku.
Expressways link the capital to other points in the Greater Tokyo area, the Kantō region, and the islands of Kyūshū and Shikoku.
Other transportation includes taxis operating in the special wards and the cities and towns. Also long-distance ferries serve the islands of Tokyo and carry passengers and cargo to domestic and foreign ports.
