Transport in Greater Tokyo

The transport network in Greater Tokyo includes public and private rail and highway networks; airports for international, domestic, and general aviation; buses; motorcycle delivery services, walking, bicycling, and commercial shipping. While the nexus is in the central part of Tokyo, every part of the Greater Tokyo Area has rail or road transport services. The sea and air transport is available from a limited number of ports for the general public.

Public transport within Greater Tokyo is dominated by the world's most extensive urban rail network (as of May 2014, the article Tokyo rail list lists 158 lines, 48 operators, 4,714.5 km of operational track and 2,210 stations [although stations recounted for each operator]) of clean and efficient surface trains and subways run by a variety of operators, with buses, trams, monorails, and other modes supporting the railway lines. The above figures do not include any Shinkansen services. However, because each operator manages only its own portion, the system is managed as a collection of rail networks rather than a single unit; many operators have ongoing upgrades and expansions underway. 40 million passengers (counted again when passing through a gate and not simply a platform) use the rail system daily (14.6 billion annually) with the subway representing 22% of that figure with 8.66 million using it daily. Extensive through services for seamless and rapid interconnections are also a feature of the network: the Narita-Haneda service run integrates track of 6 separate and independent operators. There are 0.61 commuter rail stations per square mile in the Tokyo area, or one for each 1.6 square miles of developed land area. Commuter rail ridership is very dense, at 6 million people per line mile annually, with the highest among automotive urban areas. Walking and cycling are much more common than in many cities around the globe. Private automobiles and motorcycles play a secondary role in urban transport.

Commercial flights in the region are served predominantly by Tokyo International Airport (Haneda) in Ōta, Tokyo (domestic hub for Japan's major airlines) and Narita International Airport in Narita, Chiba (main international gateway airport to the region but has also recently become a new hub for some domestic flights). Service improved to level pre-2011 following expansions but remain congested.
