Mayumi-gami, which was made from Mayumi Tree (Euonymus hamiltonianus), was the popular paper 1000 years ago in Heian-era. Murasaki Shikibu (紫式部 = author of the "Tale of Genji") and Sei Shonagon (清少納言 = author of "The Pillow Book"), both mentioned the paper named as "Mutsu-shi" or "Michinoku-gami" in their stories. It is said that that paper might be made in Kamikawasaki.
Although there is not existing Mayumi-gami anymore, this district has a long history of paper-making.
Recently, although paper-making has been quickly disappearing in this area, the people are tackling to maintain the history to the future.
