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.
Kaizu
Agriculture is the mainstay of the local economy, with rice, wheat, soybeans, cucumbers, tomatoes and green pepper as the primary crops. The city is also home to "mikan" producers. Kaizu is the northernmost point in Japan that grows "satsuma mikan" extensively.
