The Rich Tradition of Yakisugi Wood Charring

A Brief History of Yakisugi


The first time we tried the traditional Japanese method of charring the surface of our Western Red Cedar sconces and table lamps—a technique known as yakisugi—we overcooked it, just like those marshmallows you ruined while camping last weekend.


The second time, we made the opposite mistake: we undercooked it. The wood lamp lacked the uniform charred, alligator-skin finish that is characteristic of yakisugi preservation.


Since then, we’ve kept at it. We studied yakisugi’s history. We obsessed over the technique. We honed the tool of fire—applying different temperatures, at different proximities, for different durations. Gradually, with persistence, we unlocked this uncanny and unlikely finish.


At its core, yakisugi is a technique of preservation. But compared to brushing on traditional sealants, we’ve found the process to be more akin to alchemy.


This wasn’t immediately obvious. It was only when we studied the history of yakisugi that we began to grasp its deeper meaning, which is where we turn in this month’s edition of The Lamplighter Report.


Born from necessity

Yakisugi means “burnt cedar board” in Japanese. The technique originated in Tokyo in the 17th and 18th centuries out of necessity. In its 18th-century prime, Tokyo was the most populous city in the world. It featured densely built traditional wooden townhouses, which were highly flammable.


The city was a tinder box. From 1600 to 1850, the city endured nearly 1,800 fires, 49 of which were considered “great.”


Those who couldn’t afford to build with stone or stucco developed yakisugi as an affordable method of fire-hardening. Because charred wood has a higher combustion temperature than uncharred wood, charring the exterior siding of a structure reduced the risk of it becoming consumed in fire.

The Knot


To continue in this month’s theme of Japanese philosophy, Kintsugi is the process of repairing pottery with gold lacquer (a form of joinery in ceramics). It is a visual reminder that a piece can be more beautiful after having been broken. The break and the repair are parts of an object’s history that are to be featured and celebrated, not hidden.
