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.

Other grain products heavily rely on imports from other countries.
