Japan’s natural indigo dyeing tradition has been around for centuries, but the introduction of synthetic alternatives in the 1800s posed a significant threat to the industry. Despite this challenge, a few masters in Japan’s Tokushima Prefecture continue to practice the ancient art of making sukumo, a unique form of natural indigo dye. The yearlong process of growing and fermenting natural indigo is labor-intensive and time-consuming, making it difficult to compete with the efficiency and cost-effectiveness of synthetic dyes. As a result, natural indigo is now mainly used for niche purposes such as limited-edition items, while the denim industry relies heavily on synthetic alternatives, using around 55,000 tons of synthetic indigo per year.
One of the main drawbacks of synthetic indigo is its reliance on toxic chemicals and large amounts of water, making it a less sustainable option compared to natural indigo. Industry experts believe that natural indigo could serve as a more environmentally friendly alternative, but the question remains whether it can be scaled up to meet the demands of the modern market. To explore how natural indigo is still being preserved in Japan, we visited the Watanabe farm and workshop in Kamiita, where the traditional art of natural indigo dyeing is still practiced.
Despite the challenges posed by synthetic alternatives, the determination of these craftsmen to keep the eight-century-old tradition of natural indigo dyeing alive is truly remarkable. By showcasing the sustainability and uniqueness of natural indigo, they are not only preserving a valuable cultural heritage but also offering consumers a more eco-friendly option in a world increasingly concerned about environmental impact. As industries continue to explore sustainable practices, the perseverance of Japan’s natural indigo dyeing tradition serves as a testament to the enduring value of traditional craftsmanship in a modern world.
