Kurobane Aizome is an indigo-dyeing tradition passed down in the Kurobane district of Otawara City, Tochigi Prefecture. It is said to have originated when the first-generation dyer, Konya Shinbei, buried indigo vats in the ground at Kurobane and began kon-zome dyeing during the Bunka-Bunsei era (around 1804-1829). The technique uses a traditional dye made by adding wheat bran, lime, and sake to sukumo (fermented indigo leaves) from Tokushima and fermenting it further in the indigo vats, and combines this with a pre-dyeing process called kon-zome, using pine soot ink (shoen-boku) and soybean liquid, to achieve a deep, rich indigo blue that resists fading. Kurobane Aizome Konya, which has tended its indigo vats for around 200 years, is now the only workshop known to carry on this technique, and it has been designated a Tochigi Prefecture Traditional Craft. Kurobane is also known as the place where the haiku poet Matsuo Basho stayed longest during his journey recorded in Oku no Hosomichi (The Narrow Road to the Deep North) - thirteen nights over fourteen days - and the culture of indigo dyeing lives on alongside the atmosphere of this merchant town dating back to the Edo period.
Origin
Kurobane Aizome is said to have originated during the Bunka-Bunsei era (around 1804-1829), when the first-generation dyer, Konya Shinbei, buried indigo vats in the ground at Kurobane and began kon-zome dyeing. In the Edo period, Kurobane flourished as the castle town and merchant town of the Kurobane domain, and indigo dyeing developed mainly as a practical fabric for merchants' work clothes.
History
For about 200 years since then, successive generations of dyers have kept the indigo vats alive without interruption. Today, the eighth-generation artisan carries on the family trade and is the sole bearer of the Kurobane Aizome technique. The workshop has also long offered hands-on classes for local junior high school students, actively working to pass the craft on to the next generation, and it is positioned as a local cultural asset designated as a Tochigi Prefecture Traditional Craft.
Features
The characteristic of Kurobane Aizome lies in the kon-zome technique, in which fabric is pre-dyed with pine soot ink (shoen-boku) made by burning pine roots and with soybean liquid, giving the indigo a deeper color that resists fading. The dye itself is prepared through a traditional natural fermentation process, in which wheat bran, lime, and sake are added to sukumo from Tokushima and left to ferment further in the indigo vats. A paste made from cooked rice bran and rice-cake flour is used for resist-dyeing, and Ise-katagami stencils have also been used to apply patterns.
