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.
Tokushima Prefecture
Tokushima abounds in agricultural resources and is the site of large-scale production of many different types of vegetables. The plains north of the Yoshino River are particularly fertile and the produce here is often shipped to mainland Japan in the areas around Kobe, Osaka and Kyoto. Produce from Tokushima always claims top shares in markets in the Kansai region and particularly prominent are Naruto sweet potatoes, the citrus fruit "sudachi", lotus roots and strawberries.
