The History of Aizome

"Indigo entered Japan through the Silk Road around the 8th or 9th century, and as with so many other things it soon took on its own unique Japanese touch."

Japanese ukiyo-e maestro Hiroshige's woodblock print Wakamurasaki shows a young Prince Genji getting a first glimpse of lady Murasaki in an illustration from Murasaki Shikibu's The Tale of Genji, by many considered the world's first novel. Court life in the Heian period (794-1185), in which the story takes place, was characterized by gaudy kimonos in vivid colors, but Genji's in Wakamuraki stands out as it is a more subtle dark blue with a white squared pattern.

It is actually one of the first glimpses into indigo-dyeing in Japan, or aizome (藍染) as it is called from the Japanese word for indigo (ai) and to dye (someru). Indigo is the oldest plant dye known to man, used for thousands of years in places such as ancient Egypt, where mummified remains have been discovered wrapped in indigo-dyed cloths. It entered Japan through the Silk Road around the 8th or 9th century, and as with so many other things it soon took on its own unique Japanese touch. As a matter of fact, when British chemist R.W. Atkinson visited Japan in 1874 he saw so many indigo-dyed fabrics, even among commoners, that he labeled the color "Japan Blue".

But let's rewind the tape a bit. The evolution of aizome could be broken down into three stages. We have already mentioned the first, making its way into royal garments of the Heian period. The second is more practical in nature, as samurai from around the 12th century wore indigo-dyed garments under their armor as it proved to protect their skin from various ailments as well as cool it. It even had antibacterial properties, as sword-infested wounds healed quicker.

The third and final stage of the evolution took place during the Edo period (1600-1868). This is when aizome became public, so to speak. Commoners were prohibited by the Shogun to wear too explicit colors, limiting their choice of wardrobe to subdued colors such as blue, brown or grey. This didn't stop them from using their creativity, as indigo-dyed fabric provided an excellent opportunity to express one's individuality and fashion due to its unique pattern-making (more on that here). Cotton and hemp also proved relatively easy to dye with indigo, and only noblemen were allowed to wear silk.

Soon Japan exploded in a spectrum of indigo, as everyone from merchants to farmers - who like the aforementioned samurai found many practical uses in aizome's medicinal (and insect-repelling) properties - started donning aizome wear in their daily lives. Shops followed suit and dyed their noren curtains indigo, and perhaps most relevant for you reading this right now, people started sleeping on indigo-dyed bed sheets. No wonder R.W. Atkinson labeled indigo Japan Blue as it must have been literally all around him.

Aizome production thrived along the Yoshino river in Takamatsu, Shikoku, long the Mecca of indigo-dyeing in Japan. As the river often overflowed, rich silt spilled into the nearby fields, making them much more suitable for indigo than rice farming. Artisans grew by the number and perfected their skills for centuries until industrial production took over, making way for harmful but much cheaper synthetic indigo. Today Shikoku remains the nexus of natural indigo production, but very few artisans still work their trade. However, with more and more scientific reports confirming the medical benefits of natural indigo, we're standing in the dawn of a second coming of aizome.
