Infrastructure
As of 2005, one half of energy in Japan is produced from petroleum, a fifth from coal, and 14% from natural gas. Nuclear power in Japan makes a quarter of electricity production but due to the Fukushima Nuclear disaster there is large desire to end Japan's nuclear power program.
Japan's road spending has been large. The 1.2 million kilometers of paved road are the main means of transportation. Japan has left-hand traffic. A single network of speed, divided, limited-access toll roads connects major cities and are operated by toll-collecting enterprises. New and used cars are inexpensive. Car ownership fees and fuel levies are used to promote energy-efficiency.
Dozens of Japanese railway companies compete in regional and local passenger transportation markets; for instance, 7 JR enterprises, Kintetsu Corporation, Seibu Railway, and Keio Corporation. Often, strategies of these enterprises contain real estate or department stores next to stations. Some 250 high-speed Shinkansen trains connect major cities. All trains are known for punctuality.
There are 176 airports and flying is a popular way to travel between cities. The largest domestic airport, Tokyo International Airport, is Asia's second busiest airport. The largest international gateways are Narita International Airport (Tokyo area), Kansai International Airport (Osaka/Kobe/Kyoto area), and Chūbu Centrair International Airport (Nagoya area). The largest ports include Nagoya Port.
Given its heavy dependence on imported energy, Japan has aimed to diversify its sources. Since the oil shocks of the 1970s, Japan has reduced dependence on petroleum as a source of energy from more than 75% in 1973 to about 57% at present. Other important energy sources are coal, liquefied natural gas, nuclear power, and hydropower. Demand for oil is also dampened by higher government taxes on automobile engines over 2000 cc, as well as on gasoline itself, currently 54 yen per liter sold retail. Kerosene is also used extensively for home heating in portable heaters, especially farther north. Many taxi companies run their fleets on liquefied gas with tanks in the car trunks. A recent success towards greater fuel economy was the introduction of mass-produced Hybrid vehicles. Former Prime Minister Shinzo Abe, who was working on Japan's economic revival, signed a treaty with Saudi Arabia and UAE about the rising prices of oil.
