KAKISHIBU
A TANNIN-RICH DYE EXTRACT
OF THE JAPANESE PERSIMMON FRUIT
Kakishibu has a rich cultural heritage that dates back centuries in ancient Japan. This natural dye, derived from fermented unripe persimmon fruit, holds a special place in Japanese traditional crafts of textiles, paper and woodwork. Renowned for its rich amber colour, durability, and eco-friendly properties, kakishibu continues to captivate artisans.
The dyeing process involves first extracting tannins from the unripe fruit of the kaki (persimmon) tree, specifically the astringent variety known as ‘shibu’. The fruits are collected, peeled, and left to ferment in water for several months to several years. The process of fermentation allows for the release of tannic acid, which gives kakishibu its distinct characteristics.
Kakishibu on textiles has been used for centuries. The dye can be applied through various techniques, including direct application, stencil dyeing, and immersion dyeing. The result is not only a stunning colour but imbues natural fibres with enhanced durability, water repellency, and resistance to insects.
Kakishibu is used extensively in traditional Japanese fine woodworking. Wood artisans use the dye to protect and beautify a variety of wooden objects such as furniture, flooring, and tools. The tannins in kakishibu act as a natural wood preservative and offer protection against insects, fungi, and moisture. The dye enhances the natural beauty of wood by deepening its colour and creating a rich, aged, weathered appearance.
