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.
Agriculture, forestry, and fishing in Japan
Japanese agriculture has been characterized as a "sick" sector because it must contend with a variety of constraints, such as the rapidly diminishing availability of arable land and falling agricultural incomes. The problem of surplus rice was further aggravated by extensive changes in the diets of many Japanese in the 1970s and 1980s. Even a major rice crop failure did not reduce the accumulated stocks by more than 25% of the reserve. In 1990, Japan was 67% self-sufficient in agricultural products and provided for around 30% of its cereal and fodder needs.
