Asamai Shibori is a traditional tie-dye technique from the Asamai region of former Hirakata County, dating back to the late Edo period. Supported by ideal conditions for cotton and indigo production, it flourished until declining in the Taisho era, before being revived in 1982 by a preservation society. Using various tie-dye methods—such as stitching or board clamping—Asamai Shibori creates intricate, one-of-a-kind patterns in rich shades of indigo. Each piece is unique, with variations depending on the technique and number of dyeings, and can be re-dyed, adding to its longevity.
