Tokushima prefecture is japan’s biggest domestic producer of the indigo plant. By developing a unique past-like substance from the traditionally-produced indigo and treating it as a pigment rather than a dye, we 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.　 we would like to hand over our japan blue and another local valuable resource to the next generation.
