Shinkansen at Tokyo station

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 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.

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.
