Yakisugi is a product, not a burning process. The term refers to a specific type of charred wood exterior siding that has been used as a vernacular building material in Western Japan for hundreds of years. In other parts of the world, yakisugi is sometimes called “shou sugi ban” siding.

Traditional yakisugi siding starts with logs of Japanese cedar (known as “sugi” in Japan) that are holistically milled into thin planks. The wood then receives intensive flame-treatment to improve resistance to rot, UV, moisture, fire, insects, and dimensional movement versus untreated wood siding. Yakisugi’s maintenance-optional durability provides exceptional long-term cost performance over its extended natural life cycle. 

Yakisugi also offers a timeless beauty that is readily adaptable to projects. It has a quintessential wabi-sabi design aesthetic that can be finished in different ways to achieve a broad range of appearances. Learn more about authentic yakisugi.

The short answer is that there is no difference—they refer to the exact same product. But here’s how we got two competing terms for the same kind of charred Japanese cedar siding. In Japan, the term yakisugi is used exclusively to describe this material, though it is sometimes written as yakisugi-ita. 

The alternate name shou sugi ban originates from a Westerner’s misreading of yakisugi-ita, where they apparently mixed Japanese and Chinese pronunciations of the ideograms. The word “yaki” in Japanese (meaning burnt or charred) is pronounced “shou” in Chinese. “Sugi” refers to the conifer Cryptomeria japonica—a type of cedar that’s indigenous to Japan. “Ban” is the Chinese reading of the ideogram for board or plank, pronounced “ita” in Japanese. 

While the term shou sugi ban caught on in the West when the material was introduced in the 1990s, the online keyword yakisugi is appearing more frequently in searches, databases, and media. Read more about yakisugi vs shou sugi ban.

For a variety of reasons, we specify whether each of our products can be used indoors, outdoors, or both. The key distinction lies in whether the space will be exposed to direct weather conditions, regardless of whether it has conditioned air. Exterior-only products are not suitable for indoor use, and interior-only products are not suitable for outdoor use.
