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 quail
As the Japanese quail is easily managed, fast growing, small in size, and can produce eggs at a high rate, it has been farmed in large quantities across the globe. Countries such as Japan, India, China, Italy, Russia, and the United States all have established commercial Japanese quail farming industries. The Japanese quail provides developing countries with a stable source of animal proteins and developed countries with a suitable alternative to chicken. However, the quail finds its true economic and commercial value in its egg production, as domesticated lines of the Japanese quail can lay up to 300 eggs a year at a very efficient feed to egg conversion ratio.A feed to egg conversion ratio of 2.62 was accomplished by the 1990s.
