Tosa-men-tsumugi is a cotton textile known for its subdued tones, rustic handfeel, and nostalgic charm. Its origins trace back to 1804–1817, when the Tosa Domain encouraged cotton cultivation, leading to the development of this weaving tradition. In earlier times, it was also called Akaoka-jima or Kishimoto-jima after local striped patterns, and during the Meiji and Taisho periods it was commonly worn as everyday clothing. With the decline in demand for kimono, production gradually diminished. Today, Tosa-men-tsumugi survives as a folk textile preserving the legacy of Akaoka-jima stripes, valued for its simplicity and traditional character.
