Gujo-tsumugi is a silk fabric known for its rustic luster and natural shades produced with plant-based dyes. The region has a long tradition of weaving known as Gujo-ori. In the past, local farmers wove “jiori,” homespun tsumugi cloth made from hand-spun threads of waste cocoons (kuzu-mayu), primarily for their own daily use. Although production declined after the Meiji period, it was revived after World War II, with further technical advancements giving rise to the modern form of Gujo-tsumugi. The fabric is warm, soft, and comfortable to wear. Its patterns are highly varied, combining stripes and checks with ikat (kasuri), as well as curved lines and unique gradation effects (bokashi) expressed through weaving.
