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.
Japanese cuisine
In most of Japan, rice used to be consumed for almost every meal, and although a 2007 survey showed that 70% of Japanese still eat it once or twice a day, its popularity is now declining. In the 20th century there has been a shift in dietary habits, with an increasing number of people choosing wheat based products (such as bread and noodles) over rice.
