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.
Kagawa Prefecture
Olives and olive-related products have also come to be recognized as Kagawa foods. As the first place in Japan to successfully cultivate olives, Kagawa has been producing olive-related products since 1908. As well as winning both domestic and international awards for the quality of its olive oil, Kagawa has also created two offshoot food brands from its olive industry - "olive beef" and "olive yellowtail". Waste organic matter from olive pressing is used as feed for cattle and the Yellowtail Amberjack. Due to the high amount of polyphenol in the olive waste, the flesh of the respective meats does not oxidize or lose colour easily.
