Mimasaka (美作), current a part of Okayama prefecture, has been known as a paper-making district since the 8th century. The name was described on the Shōsō-in(正倉院) document.
At present, only the Ueda family in the Kami-Yokono village inherits the tradition. They use only Mitsumata, cultivated locally. The paper is used for the lining of Gold-Leaf, thin and strong, light yellow-brown coloured. That is one of the Washi which represents the Japanese culture.
