Indigo is a natural dye derived from the leaves of the indigo plant and has a rich history in Japanese culture. Japanese indigo dye is known for its deep blue hue. It has been used for centuries to dye textiles and create stunning patterns in traditional Japanese garments such as kimono and yukata. 

The process of making indigo dye is complex and involves fermentation, which produces a unique blue pigment. 

Today, indigo remains a popular dye for both traditional and modern textiles and is an essential part of Japanese cultural heritage.

The History of Japanese Indigo

The dye was first introduced to Japan from China, along with silk production techniques, during the Nara period (710-794).

During the Sengoku period (1467­–1568), an era dominated by military conflict among feudal warlords, aizome was particularly praised and appreciated by the warrior class for its beauty but primarily for its beneficial antimicrobial properties. Until the Edo period, indigo was mostly used to dye silk fabrics. But, from the 17th century, indigo dyeing became more widespread and less and less relegated to the wealthy upper classes and began to be used for cotton fabrics. During this time, the fermentation process for making the dye was developed.

The production of indigo dye was once a highly prized and valuable industry in Japan. In fact, it was so important that it was tightly controlled by the government, which set prices and regulated production. Farmers who grew indigo plants were required to sell their crops to the government, which would then distribute the dye to dyers and weavers.

During the Meiji period (1868-1912), the government began to liberalize the indigo dye industry, which led to increased competition and a decline in quality. Synthetic dyes also began to be introduced during this time, further eroding the demand for traditional indigo dye.

Making Japanese indigo dye involves thoroughly drying the indigo leaves and then fermenting them in a mixture of water, ash, and lye. This process causes a chemical reaction that releases the blue dye. The resulting liquid is then strained, and the dye can be used to color fabric. The whole process might seem straightforward, but it is long, and it can actually take more than a year before seeing the characteristic blue shade of indigo.

The particular tone, shades, and deepness of the indigo dye depend on various aspects and adjustments in the production of the pigment, and the particular blue created in Japan is often referred to as “Japan Blue.” Japan Blue is highly prized for its deep, rich tone and ability to resist fading, making it a popular choice for textiles exposed to sunlight.

Some of Japan’s most famous regions for indigo dyeing include Tokushima, where the local “Awa indigo” dyeing technique was developed. In particular, the area around Yoshino offers the perfect environment for cultivating the indigo plant.

Despite the rise of synthetic dyes, which are easier and cheaper to obtain, nowadays, the beauty and natural texture of natural indigo have been re-evaluated, and the tradition of Awa indigo has been passed on through the generations thanks to the effort of indigo artisans and other people involved, who preserve and promote Awa indigo.
