Tokushima, formerly known as Awa, is a key region for aizome, or Japanese indigo dyeing. There is a popular Japanese tongue-twister that loosely translates to "Awa is blue, blue is Awa," which highlights the deep roots of aizome in the region. Aizome is a dyeing technique that uses natural dye extracted from Persicaria tinctoria, a plant endemic to Tokushima. The dye is applied to fabric to create different shades of indigo. Aizome textiles have become extremely popular in Japan for their resistance to fading and absence of chemicals. Tokushima aizome is called Awa-ai. In its heyday, 1,500 dyers lived in Tokushima.
