The exhibition explores the history and evolution of silk cord braiding and is presented by Domyo, a Tokyo-based family-owned business that has been producing handcrafted silk cords since 1652.

From May 24 to October 23, Japan House São Paulo presents the free exhibition Kumihimo – the art of Japanese silk braiding, by Domyo. In Brazil for the first time, the exhibition is presented by Domyo, a traditional Tokyo-based family-owned business, which for over ten generations has been handcrafting silk cords, handmade by artisans who work exclusively for the company.

At the exhibition, visitors will get to know the historical evolution of kumihimo in Japan, they will understand how the braids are made, and explore future possibilities for its use, all this by means of three big installations, more than 30 reproductions of historical pieces of kumihimo, tools used by artisans, and videos with accessibility features. The exhibition is part of Japan House’s global roaming project. It has visited Los Angeles, now it is in São Paulo and, later, it will go on to London.

Braided cords

Kumihimo roughly translates into English as “braided cord”. The term is used to refer to lashings of three or more bundles of silk threads, forming strands based on the regular, uniform diagonal overlapping of these threads. The outcome may be simple, three-bundle braids (known as “French braids”), or more complex ones, sometimes with more than 140 bundles of threads.

Kumihimo has been used in Japan over the centuries for various purposes, such as accessories for clothing and ornaments for weapons and armor, and it has undergone a unique evolution. One of the types the Japanese know best is the braid used in obijime – the narrow belt that is tied over the belt of a traditional kimono.

History, Structure, and Future of Kumihimo

Divided into three moments – History, Structure, and Future -, the exhibition occupies the entire second floor of Japan House São Paulo, including a new 100-square-meter room that will be incorporated into this floor from this exhibition.

In the historical part, the focus is on the origins and evolution of the technique over the centuries. Meanwhile, the stands used to produce the cords, the marudai (used to make square cords) and takadai (a high stand that allows for the making of flat braids), are presented to visitors in the Structure section, which also features the tools used in yarn dyeing and preparation and in cord production processes. Finally, visitors can check out the latest braiding structures developed by Domyo, as well as pieces created in collaboration with specialists from areas such as the textile industry and mathematical sciences, which present possibilities for future applications of the technique.

Resistance and Elasticity of Kumihimo

Kumihimo stands out both for its strength and elasticity, factors determined by the braiding and lashing methods that are used, in addition to variations in fiber angle orientation, which is why you can find carbon tube structures similar to kumihimo in a range of industrial applications, from golf clubs and aircraft to orthopedic prostheses.

A model based on geometric topology was created in partnership with the University of Tokyo’s Tachi Lab. exclusively for this exhibition. The model presented is the outcome of the activity of this laboratory, where researchers create usable structures and cellular materials with unique properties based on the geometry of the origami, in systems with joints and in differential geometry, among others. Through this work, they seek to understand the nature of form and function, through observation and the creation of various phenomena. Through this collaboration, the potential offered by kumihimo will be mathematically expanded in order to create graphic patterns, three-dimensional structures, and functional systems.
