In accordance with the city's world position, Tokyo's economy has shifted to put much more emphasis on financial services and banking. It is also an important wholesale center. Among the diverse industries of Tokyo are the manufacture of electronic apparatus, transport equipment, automobiles, cameras and optical goods, furniture, textiles, and a wide variety of consumer items, as well as publishing and printing.
The city, which lies on the Kanto plain, is intersected by the Sumida River and has an extensive network of canals. Yokohama is its seaport, but there is a large man-made port at the mouth of the Sumida, through which such items as electrical products, cameras, and automobiles are exported. The deepening of Tokyo's harbor and the development of storage facilities have gradually lessened the city's dependence on Yokohama. Land reclamation projects in Tokyo Bay have led to waste disposal islands, additional port functions, and even new residential developments.
Tokyo has an outstanding subway system, and the world's first public monorail line runs between downtown and Haneda international airport. Narita International is Tokyo's main airport. The transportation system also includes the Shinkansen, whose "bullet trains" connect Tokyo with Osaka and other cities.
