Some Things About Indigo As Your Brain Processes These Jeans

Indigo is purported to be the oldest dye used by humans worldwide, introduced to Japan around 1500 years ago. Originally it was considered a noble color predominantly worn by courts and upper aristocrats during the Heian period. It was during the Edo period that indigo spread among the common people, and it is said that kimonos, work clothes, shop curtains, and even bedclothes were gettin’ dyed in indigo. Revered by the Japanese as an “auspicious” color, indigo was the symbolic color of Japan during the Meiji era, referred to as "Japan Blue" in other countries.

Indigo dyeing in Tokushima is rumoured to have been introduced to Japan around 900 AD by the lord of Awa, Hachisuka, who recognized that the climate along the Yoshino River was suitable for indigo cultivation. The technique used in indigo dyeing in Tokushima is called "fermentation," with Awa indigo as a raw material. Since it cannot be dyed to a dark shade all at once, the process of dyeing, squeezing, and drying is repeated many times. It is said that the authentic color achieved through the Awa Shoai dyeing technique (hank dyeing) is obtained after washing with water about 30 times, during which the uneven color is washed off until a deep shade is achieved. 

This method of creating indigo dye is labor-intensive and incredibly time-consuming. Leaves are carefully gathered from the indigo plant and placed under thick straw mats for months on end. To ensure the leaves ferment properly, very specific conditions must be consistently maintained. Workers must perform daily maintenance to ensure that the leaves have proper airflow and stay at a temperature around 60 degrees Fahrenheit.

From picking the leaves to completion, the entire fermentation process takes approximately one full year. Finally, after months of patience and dedicated work, the final result is something that resembles dirt, but with a pungent, vinegary aroma. This product, known as "sukumo," serves as the basis for indigo dye.

Just as the indigo dyers of hundreds of years ago, the "Aizome" dyeing is a manual process, done on hands and knees while leaning over a large metal vat of inky blue indigo dye. The shade of blue after one dip will be very light, and the dipping process must be repeated multiple times to achieve darker colors.
