It handles more than 3 million passengers each day. Trains are notoriously crowded, especially during morning rush hours, and are often filled to more than double their capacity. The Yamanote Line is Tokyo's most crowded. Much of the street pattern of Tokyo dates to historic times and is made of narrow, crooked lanes that are unsuitable for heavy use by automobiles. The radiating highways and expressways that were put in to modernize the road network are usually badly overcrowded, and traffic moves at a slow pace.
Parking is a major problem.
A person must provide proof of an off-street, overnight parking space to own a car in Tokyo. Tokyo's major airport is the New Tokyo International Airport, also called Narita Airport. Narita Airport is reached by two railways, the Narita Line and the Keisei Line, as well as limousine bus service. More than 20 million passengers use this airport each year. Narita is also important as an air freight port, particularly for imports of fresh foods, magazines, and newspapers.
