Production Process of Honminoshi Paper: The Charm and Techniques of Traditional Japanese Paper Making

The Charm and Characteristics of Honminoshi Paper

Honminoshi paper is one of Japan’s traditional washi papers, made from Daigo Nasu Kozo (paper mulberry) produced in Ibaraki Prefecture, known for its long and strong fibers. This washi, made from the white bark of kozo, is characterized by its delicate and beautiful texture. Craftsmen use unique techniques to pulp the paper, creating an orderly interlacing of fibers visible when light passes through.

Background and Cultural Significance

Honminoshi paper is made using the pure water of the Satoyama area in Gifu Prefecture, with craftsmen preserving tradition by hand-pulping each sheet. It is said that pulping during the cold season produces high-quality paper, making it a craft that fuses techniques cultivated over a long history with the natural environment.

Production Process and Materials

The raw material Daigo Nasu Kozo is harvested after leaf fall, with the black bark removed to use only the white bark. The white bark is soaked in clear streams for several days for natural bleaching and impurity removal. Next, it undergoes lye removal in an iron kettle fueled by firewood to soften the fibers. After washing, the fibers are beaten with wooden mallets to shorten and separate them, then mixed with the mucilaginous tororo-aoi before papermaking. The papermaking screen is made using the “sogitsugi” technique, where bamboo strips are cut diagonally and joined, producing the delicate papermaking marks unique to Honminoshi paper. The papermaking method involves not only vertical shaking but also horizontal shaking, resulting in beautifully interlaced fibers arranged vertically and horizontally. Drying is done by attaching the sheets to horse chestnut boards and sun-drying, producing natural bleaching and a glossy texture. Finally, selection is performed to maintain quality.

Production Area and Visit Information

Honminoshi paper is produced in the Satoyama region of Gifu Prefecture, where pure water and natural environment are indispensable for manufacturing. Many craftsmen preserve traditional techniques, and visitors can learn about the production process at local craft centers and cooperatives. When visiting or purchasing, it is advisable to check information from official production cooperatives or craft centers.
