Agriculture, forestry, and fishing in Japan
Agriculture, farming, and fishing form the primary sector of industry of the Japanese economy together with the Japanese mining industry, but together they account for only 1.3% of gross national product. Only 20% of Japan's land is suitable for cultivation, and the agricultural economy is highly subsidized.
Korea under Japanese rule
By 1910 an estimated 7 to 8% of all arable land in Korea had come under Japanese control. This ratio increased steadily; as of the years 1916, 1920, and 1932, the ratio of Japanese land ownership increased from 36.8 to 39.8 to 52.7%. The level of tenancy was similar to that of farmers in Japan itself; however, in Korea, the landowners were mostly Japanese, while the tenants were all Koreans. As often occurred in Japan itself, tenants had to pay over half their crop as rent, forcing many to send wives and daughters into factories or prostitution so they could pay taxes.
