The Japanese craft of Yakisugi is—due to a botched translation—mistakenly called Shou Sugi Ban in the West. This technique has been used for centuries in Japan and is growing in popularity around the world. Here's what to know.
What Is Shou Sugi Ban (Yakisugi)?
Shou Sugi Ban, also known as Yakisugi, is a decorative and architectural wood-burning technique that has been used for centuries in Japan. This traditional Japanese wood preservation method involves voluntarily charring wood to create a textural surface that is beautiful to look at—and that offers practical advantages when executed correctly.
The Shou Sugi Ban technique involves charring clean wood before cooling, brushing, washing, and finally finishing it with oil to protect it and make it more durable.
Shou Sugi Ban wood can be used as a treatment on outdoor architectural elements such as siding, as well as indoors on walls and furniture. The aesthetic qualities of Shou Sugi Ban have inspired a revived interest in the wood-charring technique in recent years, which has become a prominent trend in architecture and interior design globally.

The Origins of Shou Sugi Ban (Yakisugi)
Shou Sugi Ban (or Yakisugi, as it is known in Japan) means “burned cedar.” It is an ingenious 18th-century Japanese wood burning technique that creates an intriguing charred appearance that highlights natural wood veining, creates textural interest, and varies in appearance according to how much fire is applied and which type of wood is used. (Japanese Cypress is considered the gold standard for purists, although other wood types can be used to varying degrees of success.)
While it might seem counterintuitive, the act of charring wood doesn’t make it structurally weaker, but magically has the opposite effect. Burning the surface of the wood under controlled conditions fortifies and protects the wood against future damage, making it an excellent preservation technique.
The use of Shou Sugi Ban in traditional Japanese architecture predates the practice of using chemicals to protect wood siding. Achieving Shou Sugi Ban involves a process that includes carefully selecting virgin wood that is cut into planks, dried in the sun or open air, burned on the surface to create a thin layer of char, then brushed and sealed with oil. This process can be done manually by everyone from master craftsmen to DIY enthusiasts, or by using machine automation.

This centuries-old technique lends a fresh and contemporary edge to modern architecture. The distinctive look of deeply saturated charcoal black wood has an understated but powerful presence that creates instant drama and interest on even the most minimalist structures and applications.
In recent years, the look of Shou Sugi Ban has become so on-trend that it has inspired designers to experiment with charred wood in surprising ways. Dutch designer Maarten Baas is known for his Smoke series for luxury brand Moooi that includes a charred armchair and a blackened wood chandelier that is sealed with transparent epoxy resin. Inspired by Shou Sugi Ban, Baas and Dutch designer Piet Hein Eek designed Burnt Wood Wallpaper for NLXL that offers an accessible trompe l'oeil way to incorporate the look. And you can now find faux Shou Sugi Ban panels made from treated (but not charred), reclaimed (rather than new) wood on the market, as well.

FAQ
What kind of wood should you use for Shou Sugi Ban?
Cedar is the traditional wood of preference for Shou Sugi Ban. But you can also use woods such as pine, oak, spruce, or larch to varying shades and effects depending on the quality of the source material. It’s a good idea to test it out first to make sure you are using the right wood to achieve the depth of color and look you want.
Do you have to seal wood after Shou Sugi Ban?
While the process of charring wood makes it stronger than untreated wood, it’s still a good idea to seal wood that’s been given the Shou Sugi Ban treatment. Apply mineral or linseed oil with a paintbrush to protect charred wood, particularly if it is being used outdoors and exposed to elements such as sun and rain.
What is the lifespan of Shou Sugi Ban wood?
Shou Sugi Ban wood will last longer indoors than out. According to HomeAdvisor, your Shou Sugi Ban wood siding should last between 30 to 50 years with regular maintenance. This means keeping an eye on the wood for signs of damage and reapplying oil as needed to preserve and protect it. Indoor Shou Sugi Ban wood can last even longer, with some estimates at more than 100 years.
