Why Nishijin Weaving Has Used Silk for Over 1,200 Years

Nishijin weaving is best known for its luxurious kimono obi, celebrated for intricate patterns, elegant luster, and an exceptionally soft drape. At the heart of these remarkable textiles is silk.
Today, a wide range of fibers—including polyester, cotton, and nylon—are used in textile production. Yet for more than 1,200 years, Nishijin weaving has continued to rely on silk.
Why has silk remained the material of choice for over twelve centuries? Discover the unique qualities that have made it the foundation of Japan's finest luxury textiles.

Silk textiles are premium woven fabrics made from natural silk fibers. For centuries, they have been treasured across Japan, China, Italy, and other parts of the world for their elegant luster, soft drape, and exceptional durability. Today, silk textiles continue to be used in luxury fashion, interior design, and traditional craftsmanship.
In Italy, Como Silk—produced around Lake Como—is renowned as one of the world's finest silk textiles and is used by many luxury fashion houses. In Japan, Nishijin weaving has been perfected over more than 1,200 years, creating exquisite silk textiles distinguished by intricate patterns, refined craftsmanship, and timeless beauty. Today, Nishijin remains one of Japan's most iconic silk textile traditions.

Silk is a natural fiber produced by the silkworm (Bombyx mori). After hatching, the silkworm grows for about 25 days, molting five times before reaching maturity. It then spends approximately two days spinning a single continuous filament to form its protective cocoon.

Inside the cocoon, the silkworm transforms into a pupa over the course of about 12 days before emerging as a moth. Nishijin silk is carefully reeled from these cocoons, preserving the long, unbroken fibers that give silk its exceptional quality.

Although each filament is remarkably fine, it is also exceptionally strong. This rare combination of strength, natural luster, and graceful drape has made silk one of the world's most prized textile fibers for centuries, forming the foundation of luxury textiles such as Nishijin weaving.

Silk is composed of two natural proteins: fibroin and sericin.
Fibroin forms the core of the silk fiber, providing its remarkable strength, elegant luster, and smooth drape. Sericin is a natural protein that surrounds the fibroin, binding and protecting the delicate filaments.
During silk production, sericin is removed through a process known as degumming, in which the fibers are gently washed in hot water. This essential step reveals silk's characteristic softness, natural sheen, and refined texture.
For Nishijin weaving, careful degumming is one of the key processes that determines the quality and beauty of the finished textile.

Nishijin weaving creates intricate patterns using thousands of individual threads within the narrow width of a kimono obi. If the yarns were thicker, the level of detail that could be achieved would be limited. Silk, however, is exceptionally fine while offering remarkable tensile strength, allowing artisans to weave highly detailed and complex designs.
This unique quality makes it possible to create the delicate floral motifs, arabesque patterns, phoenixes, and other traditional Japanese designs that define Nishijin textiles.

At Kawase Mitsu Orimono, advanced Jacquard weaving technology further expands these possibilities, enabling even more intricate patterns, rich textures, and three-dimensional expressions while preserving the craftsmanship of traditional Nishijin weaving.

At Kawase Mitsu Orimono, the craftsmanship of Nishijin weaving extends far beyond traditional kimono obi. Our expertise is applied to neckties, interior textiles, art panels, cushions, and custom textiles created for fashion brands and designers around the world.
The natural luster, refined texture, and intricate expressive qualities of silk allow Nishijin weaving to transcend traditional craftsmanship, bringing new value to contemporary luxury fashion, interior design, and bespoke textile creation.

For more than 1,200 years, Nishijin weaving has continued to evolve while preserving its heritage. Today, that legacy inspires new collaborations with designers, architects, and creative brands, shaping the future of luxury textiles through Japanese craftsmanship.

Nishijin weaving has continued to rely on silk for more than 1,200 years—not simply because of its beauty, but because of its exceptional performance.
Each fine silk filament produced by the silkworm combines remarkable strength with extraordinary flexibility, making it possible to create intricate patterns, rich colors, and the refined luster that define Nishijin textiles.
For over twelve centuries, artisans in Kyoto have refined this natural material into one of Japan's most celebrated luxury textile traditions, bringing out the full potential of silk through generations of craftsmanship.
At Kawase Mitsu Orimono, we carry this tradition into the future by applying Nishijin weaving to far more than kimono obi. From fashion textiles and neckties to interior fabrics, art panels, and bespoke collaborations, we continue to explore new possibilities for silk.
Our commitment to silk is not only about preserving tradition—it is about creating the next generation of luxury textiles through Japanese craftsmanship.

At Kawase Mitsu Orimono, we are committed to introducing the beauty and craftsmanship of Nishijin textiles to the world. Through initiatives such as visiting the Embassy of Japan in the Czech Republic, building relationships with the Mucha Foundation, and exhibiting at Milano Unica, one of the world's leading textile trade fairs, we continue to expand the global presence of Kyoto's Nishijin weaving.
By sharing Japan's traditional weaving techniques internationally and fostering cultural exchange, we strive to create new value for Nishijin textiles. Through collaboration with designers, brands, and creative industries around the world, we are shaping the future of luxury silk textiles while preserving a craftsmanship that has been refined for more than 1,200 years.

At Milano Unica, one of the world's leading textile trade fairs held in Milan, Italy, the Nishijin Textile Collection showcased new possibilities for the centuries-old art of Nishijin weaving.
The collection brought together renowned Nishijin weaving houses, including Kawase Mitsu Orimono, Morisan, Taiyo Necktie, and Tomiya, each contributing its own distinctive craftsmanship and creative approach. Together, they presented innovative textiles for fashion, interiors, and lifestyle applications, introducing the versatility and beauty of Nishijin weaving to an international audience.

Kawase Mitsu Orimono is the only Nishijin weaving house in the world officially licensed by the Mucha Foundation to recreate the works of Alphonse Mucha through the art of Nishijin weaving.
Around a decade ago, representatives of the Mucha Foundation visited our workshop in Kyoto's Nishijin district, where they experienced the unique qualities of our textiles firsthand—including their rich three-dimensional texture, the elegance of natural silk, and the subtle play of light that can only be achieved through weaving rather than printing.

They recognized our ability to faithfully reproduce Mucha's intricate linework and decorative beauty using traditional Nishijin weaving techniques. That recognition became the foundation of this unique collaboration.
