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.
Berry
Berries also began to be cultivated in Europe and other countries. Some species of blackberries and raspberries of the genus "Rubus" have been cultivated since the 17th century, while smooth-skinned blueberries and cranberries of the genus "Vaccinium" have been cultivated in the United States for over a century. In Japan, between the 10th and 18th centuries, the term referred to many berry crops. The most widely cultivated berry of modern times, however, is the strawberry, which is produced globally at twice the amount of all other berry crops combined.
