Aizome, or indigo dye, is a traditional Japanese dyeing technique that uses the leaves of the indigo plant. This natural dye has been used for centuries to create deep blue textiles, prized for their vibrant color and durability. The dyeing process involves fermenting the leaves to extract the indigo pigment, which is then applied to fabrics like cotton and silk. In Japan, Aizome is not just a craft but also a cultural heritage. The dyeing technique is often associated with the Bingata style of textile art and has been recognized for its environmental sustainability. Today, Aizome continues to be celebrated in fashion and art, reflecting a blend of tradition and modernity.
