Dried sweet potatoes are a processed sweet potato product that is popular among men and women of all ages. Ibaraki Prefecture is the top producer of dried sweet potatoes in Japan. Hitachinaka City, Tokai Village, and Naka City produce most of it. Dried sweet potatoes are said to have originated in Shizuoka Prefecture, where they were introduced to Japan after Osawa Gonemon saved a ship from Satsuma (now Kagoshima Prefecture) that was in distress. As the cultivation of sweet potatoes spread in Shizuoka Prefecture, a man named Shozo Kuribayashi came up with the idea of boiling sweet potatoes, cutting them into thin slices with a knife, and then drying them. This is said to have been the beginning of "dried taro." Because of its convenience in that it could be eaten at any time and preserved, it quickly spread to the Kanto region. Later, Terunuma Kantaro, who was lost off the coast of Shizuoka Prefecture, began making dried shiitake in Ibaraki Prefecture from the dried shiitake he had seen in Shizuoka Prefecture. Then, it is said that production of dried taro increased dramatically when Toshichi Yuasa and Kihei Koike, who ran a rice cracker shop in Nakaminato City (present-day Hitachinaka City), began to produce and sell dried taro. At Horide Shrine in Ajigaura, there is a bust of Kibei as the person who popularized "dried sweet potatoes. Production of dried taro practically stopped after the war, when sweet potatoes replaced other staple foods, but was revived after the war with the encouragement of the prefectural government.
