Tōhoku region
Tōhoku was traditionally considered the granary of Japan because it supplied Sendai and the Tokyo-Yokohama market with rice and other farming commodities. Tōhoku provided 20 percent of the nation's rice crop. The climate, however, is harsher than in other parts of Honshū due to the stronger effect of the Siberian High, and permits only one crop a year on paddy fields.
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.
