Japanese tissue

Japanese tissue is a thin, strong paper made from vegetable fibers. Japanese tissue may be made from one of three plants, the kozo plant (Broussonetia papyrifera, paper mulberry tree), the mitsumata (Edgeworthia chrysantha) shrub and the gampi tree (Diplomorpha sikokiana). The long, strong fibers of the kozo plant produce very strong, dimensionally stable papers, and are the most commonly used fibers in the making of Japanese paper (washi). Tissue made from kozo, or kozogami (楮紙), comes in varying thicknesses and colors, and is an ideal paper to use in the mending of books. The majority of mending tissues are made from kozo fibers, though mitsumata and gampi papers also are used.
