The history of Mino Washi goes back to the sixth century. Mino Washi is one of those traditional Japanese papers, which were used to keep records of important documents. Because of clear rivers and streams in Gifu Pref., paper industries have made handmade paper for a long time. Mino Washi is made from the fibers of kouzo, paper mulberry, through many processes. Its thinness and toughness can be ranked in the highest quality among many other washi papers. Even now, Mino Washi is used for important documents, which should be in good condition so many years. It is also used to mend National treasures. Mino Washi is used for lighting equipments in a guesthouse for VIP from abroad, which is under construction in Kyoto Pref.
