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 km? (14 million acres) cultivated.

Japan's small agricultural sector, however, is also highly subsidized and protected, with government regulations that favor small-scale cultivation instead of large-scale agriculture as practiced in North America.

Imported rice, the most protected crop, is subject to tariffs of 490% and was restricted to a quota of only 7.2% of average rice consumption from 1968 to 1988. Imports beyond the quota are unrestricted in legal terms, but subject to a 341 yen per kilogram tariff. This tariff is now estimated at 490%, but the rate will soar to a massive 778% under new calculation rules to be introduced as part of the Doha Round.

Although Japan is usually self-sufficient in rice (except for its use in making rice crackers and processed foods) and wheat, the country must import about 50% of its requirements of other grain and fodder crops and relies on imports for most of its supply of meat. Japan imports large quantities of wheat, sorghum, and soybeans, primarily from the United States. Japan is the largest market for EU agricultural exports. Apples are also grown, mostly in Tohoku and Hokkaid?; Pears and Oranges are mainly grown in Shikoku and in Ky?sh?. Pears and oranges were first introduced by Dutch traders, in Nagasaki in the late 18th century
