In Japan, Tokushima is a key producer of indigo plant and has a history which dates back to more than 700 years ago. The region was well known for supplying beautiful colourfast and high-grade dye to all over the country. By developing a unique paste-like substance from the traditionally-produced indigo and treating it as a pigment rather than a dye, makers over generations established a technology that can be used as a paint or spray and applied it to designs that make use of grain as part of construction materials, interiors, or small objects. AOLA focuses on local materials. Amongst them, the Indigo Cedar Wood Coasters is a trademark of Tokushima’s indigo dyeing culture, also known as Japan Blue.
