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.
Geography of Japan
The terrain of Japan is mostly rugged and mountainous with 66% forest. This caused the population to be clustered in urban areas on the coast, plains and valleys. In 2010, 90.7% of the total Japanese population lived in cities. Japan is an urban society with about only 5% of the labor force working in agriculture. About 80 million of the urban population is heavily concentrated on the Pacific coast of Honshu.
