Washi

Our Washi

Washi (Wa = Japanese, shi = paper), is a traditional Japanese material with over 1300 years of history, the production of which involves a complex, multi-step process that has been passed down through the generations.  

A sustainable material, often made from the fibers of the kozo (paper mulberry) tree, it is known for its strength, durability, and unique textures.  Washi is used for a wide range of purposes, such as calligraphy, shoji sliding doors, lanterns, lampshades, clothing and more.

All of our washi is made in Fukuoka, Japan by Yuki Yoshimura.  Using traditional methods, each layer is carefully crafted by hand, creating variations of thickness and patterns.  Between layers are placed different materials, such as bark, plant fibers, leaves, etc, to create distinct designs.  When light passes through the washi, these characteristics are further enhanced, showcasing the complex and visually appealing texture of the paper.

While much of the washi on the market is known and touted for its thinness and delicate look, our washi often has a more rugged or sometimes even rough look to it.  This is because of the tame-suki method, a traditional Japanese papermaking method in which the washi pulp is allowed to settle naturally in the mold before the water drains away. Unlike the more common nagashi-suki technique—where the pulp is moved repeatedly to create a smooth, even sheet—tame-suki lets the fibers rest in place.

This slower process creates washi with a slightly thicker body, soft texture, and gentle natural variations. These organic patterns give each sheet its own character, making tame-suki washi especially beautiful for lighting, where its depth and warmth come alive when illuminated.

We also often apply konnyaku glue, a natural material made from the starch of the konjac plant, traditionally used to treat washi to make it even more durable.  With this treatment, the washi has an added layer of protection from water damage, but it also gives more structure to the paper for uses such as upright lampshades or other lamps.

Washi and Light

Washi is renowned for its distinctive translucency. While other translucent materials—such as frosted glass, Western paper, and plastics—are commonly employed, washi exhibits structural and aesthetic characteristics that set it apart.

Its long fibers intertwine in a complex and irregular manner, creating gaps of varying sizes between them. As light passes through these gaps, it produces the soft, warm illumination that is emblematic of washi.

Even when several sheets are layered, washi retains a remarkably high degree of translucency. This unique property has contributed to its enduring use in Japanese architecture, lighting design, and traditional crafts.
