In 1999, Japanese owned approximately 73.69 million vehicles (49.97 million passenger cars; 18.86 million cargo vehicles, and 4.86 million other types of vehicles). This is an increase of around 18.55 million vehicles over a 10-year period. In contrast to the rapid proliferation of cars, however, development of roads has not kept pace, and morning and evening traffic jams, particularly in urban areas, are common. Expressways are no exception, despite high toll charges. Currently, the Japan Highway Public Corporation (JH) maintains 9,064 kilometers of expressway, charging a toll of 24.6 yen per kilometer for standard passenger cars. The first expressway in Japan was opened to traffic in 1963 and consisted of 71.1 kilometers of the Meishin Expressway between the Kurihigashi Interchange in Shiga prefecture and the Amagasaki Interchange in Hyogo prefecture.
