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.
Environmental issues in Japan
In the Japanese diets, fish and its products are more prominent than other types of meat. Because of the depletion of ocean stocks in the late 20th century, Japan's total annual fish catch has been diminishing rapidly. Japan, along with the United States and the European Union, occupies the large part of international fish trade. Japanese fish catches were the third in the world in 2000, following China and Peru. The United States, Chile, Indonesia, the Russian Federation and India were other major countries.
