[9] During the Genpei War (1180–1185) between the Taira and Minamoto clans in the late-Heian period, Tottori became a base for anti-Taira forces, specifically at two temples, Daisen-ji and Sanbutsu-ji.By the beginning of the Kamakura period (1185–1333) shōen estates were established to directly support the Imperial court and various temples.In the postwar period land reform was carried out in the prefecture, resulting in a great increase of agricultural production.Tottori Prefecture is heavily agricultural and its products are shipped to the major cities of Japan.Some of the famous products are the nashi pear, nagaimo yam, Japanese scallion, negi, and watermelon.
