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 Manchukuo
The effective annexation gave Japan an area suitable for farming, such as scarcely existed on the country's islands, or other parts, generally mountainous, of the Empire of Japan. The area was primarily agricultural in character, although with some urbanization. Agriculture employed 85% of the population.
