The traditional Japanese craft known as Yakisugi is referred to in the West as burnt timber cladding or shou sugi ban (焼杉板), a term which uses the same kanji characters but an alternative pronunciation (the ban character means “plank”). This ancient wood preservation technique has been used in Japan for centuries and is now gaining popularity worldwide. Here’s a quick look at what you need to know about Shou Sugi Ban.

What Is Shou Sugi Ban (Yakisugi)?

Shou Sugi Ban, or Yakisugi, is a wood-burning technique used for both decorative and architectural purposes. This method, rooted in Japanese tradition, involves charring wood surfaces to create a unique, textured appearance that is both visually striking and practically beneficial when done correctly.

The process of Shou Sugi Ban includes burning clean wood, then cooling, brushing, washing, and finishing it with oil. This technique not only enhances the wood’s beauty but also increases its durability and protection.

Shou Sugi Ban-treated wood can be used in various applications, from outdoor architectural elements like siding to indoor features such as walls and furniture. The aesthetic appeal of this technique has sparked renewed interest in recent years, becoming a notable trend in both architecture and interior design globally.

The Origins of Shou Sugi Ban (Yakisugi)

Shou Sugi Ban, also known as Yakisugi in Japan, translates to “burned cedar.” This ingenious 18th-century technique creates a charred look that highlights the natural grain of the wood, adding textural interest. The appearance varies depending on the intensity of the fire and the type of wood used, with Japanese Cypress being the preferred choice for traditionalists, though other woods can also be used successfully.

Contrary to what one might expect, charring the wood surface doesn’t weaken it. Instead, it strengthens the wood, protecting it from future damage. This makes Shou Sugi Ban an excellent preservation method.

Historically, Shou Sugi Ban was used in Japanese architecture long before chemical treatments for wood siding were available. The process involves selecting high-quality wood, cutting it into planks, drying it, burning the surface to create a char layer, brushing, and sealing with oil. This technique can be performed manually by craftsmen or through automated machinery.

Modern Applications and Trends

The timeless technique of Shou Sugi Ban lends a modern, edgy appeal to contemporary architecture. The deep, charcoal-black wood creates a dramatic effect, making even minimalist structures stand out.

Recently, the unique look of Shou Sugi Ban has inspired designers to experiment with charred wood in innovative ways. Dutch designer Maarten Baas, for instance, created the Smoke series for the luxury brand Moooi, featuring charred furniture sealed with epoxy resin. Baas, along with Piet Hein Eek, also designed Burnt Wood Wallpaper for NLXL, offering a faux-charred wood look.

Faux Shou Sugi Ban panels, made from treated or reclaimed wood, are now available, making this distinctive style more accessible.
