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.
Niigata Prefecture
Niigata Prefecture produces the highest volume of azaleas and cut lilies in Japan, and is increasing production of cut flowers and flower bulbs. Along with Toyama Prefecture, it produces the highest volume of tulips in the country.
