Economy of 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 56,000 km² (14 million acres) cultivated.
Economy of Japan
Japan's mining production has been minimal, and Japan has very little mining deposits. However, massive deposits of rare earths have been found off the coast of Japan. In the 2011 fiscal year, the domestic yield of crude oil was 820 thousand kiloliters, which was 0.4% of Japan's total crude processing volume.
