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.
Vegetarianism by country
According to a 2014/12 survey 4.7% of the Japanese population are vegetarian or vegan (2.7% vegan). NOTE: The referenced web survey included 1,188 valid responses and is not representative of the population of Japan.
