Tosa Washi Paper: A Thousand-Year Tradition of Kochi's Paper Culture

Kochi Prefecture (Tosa) is, alongside Echizen and Mino, one of Japan three great washi paper regions, and is said to lead the nation in the variety of paper it produces. Centered on Ino Town and made on the banks of the clear Niyodo River, Tosa washi has built up over a thousand years of history as a thin, strong, and beautiful paper. It is a craft Kochi is proud of, one where you can feel the warmth of paper made by hand.

Highlights

A Thousand Years of Papermaking

Papermaking in Tosa is old enough to appear in Heian-period records; the Engishiki, a legal code completed in 927, is said to hold some of the oldest records of Tosa paper. Rich in fine raw materials such as kozo (paper mulberry) and mitsumata, and blessed with the clean water essential to papermaking, Tosa grew into a major paper-producing region. In the Edo period, production expanded under the protection of the Tosa domain, and techniques continued to be refined from the Meiji era onward. The ultra-thin Tosa tengujoshi, described as being like "the wings of a mayfly," is known as one of the world thinnest handmade papers and is used in the restoration of cultural properties.

Clear-Stream Paper Nurtured by the Niyodo River

What has supported the quality of Tosa washi is the clear water of the Niyodo River, praised as "Niyodo Blue." The papermaking process requires large amounts of clean water, and clear-stream-blessed Ino Town was an ideal place for it. Washi made with cold, clear water has evenly aligned fibers and, though thin, is strong and hard to tear. Papermaking that lives alongside the river reflects a beautiful culture where Tosa nature and human life are intertwined.

A Rich Variety of Papers

Tosa washi is also known for the great variety of its papers. From the very thin tengujoshi to calligraphy paper, shoji paper, art paper, and restoration paper, papers for many uses have been made here. In recent years, its strength and texture have drawn attention as a material for lighting, interiors, and contemporary art.

Seasonal Enjoyment

Tosa washi experiences and visits can be enjoyed year-round, and visiting in the fresh green or summer season, when the Niyodo River is beautiful, also lets you enjoy the nature behind the papermaking. Autumn pairs with the foliage of the Niyodo basin, while winter offers a quiet setting to dive into the world of papermaking. It is a mainly indoor cultural experience that can be enjoyed in any season.
