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.
Persimmon
Asian or Japanese persimmon ("Diospyros kaki") is the commercially most important persimmon, and is native to Japan, China, Korea, Myanmar and Nepal. It is deciduous, with broad, stiff leaves, and is known as the "shizi" (柿子 in Chinese), and also as the Japanese Persimmon or kaki (柿) in Japanese. Its fruits are sweet and slightly tangy with a soft to occasionally fibrous texture. Cultivation of the fruit extended first to other parts of east Asia, India and Nepal, and it was later introduced to California and southern Europe in the 1800s and to Brazil in the 1890s.
