How Japan's 800-year-old indigo dyeing process is still standing
Briefly

Natural indigo dye has a rich history of thousands of years but faced a significant downturn due to the introduction of synthetic indigo in the 1800s. In Japan's Tokushima Prefecture, skilled artisans continue the time-honored tradition of creating sukumo indigo, a unique type that takes a year to produce. Unfortunately, the efficiency and low cost of synthetic indigo, which is heavily used in the denim industry, limit the adoption of natural indigo. Despite its sustainable benefits—free from toxic chemicals—the challenge remains whether natural indigo can be produced at scale for wider usage.
Natural indigo dye has been used globally for thousands of years, but the arrival of synthetic indigo in the 1800s significantly impacted its production and usage.
In Japan's Tokushima Prefecture, a few artisans still practice the ancient craft of sukumo indigo dyeing, a tradition dating back eight centuries.
