Kaihara, a Hiroshima-based denim mill, pioneered handwoven authentic indigo-dyed kasuri in 1983 and invented Japan’s first rope dyeing machine in 1893. Kaihara focuses on quality, rich indigo hues, and unique textures, blending traditional craftsmanship with innovation to produce durable denim that conserves water by 20%. They produce organic cotton and recycled cotton (cotton dirt) waste from production, saving approximately 10 gallons of water per denim roll1.
