Japan
The Japanese agricultural sector accounts for about 1.4% of the total country's GDP. Only 12% of Japan's land is suitable for cultivation. Due to this lack of arable land, a system of terraces is used to farm in small areas. This results in one of the world's highest levels of crop yields per unit area, with an overall agricultural self-sufficiency rate of about 50% on fewer than cultivated.
Economy of Japan
Japan's spendings on roads has been considered large. The 1.2 million kilometers of paved road are one of the major 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, and the Japanese government has encouraged people to buy hybrid vehicles. Car ownership fees and fuel levies are used to promote energy-efficiency.
