Yakisugi () is a traditional Japanese method of wood preservation. Yaki means to heat with fire, and sugi is cypress.[1] It is also referred to in the West as shō sugi ban (焼杉板),[2] which uses the same kanji characters but a different pronunciation. The ban character means "plank".

By slightly charring the surface of the wood without combusting the whole piece, the wood becomes water-proof through the carbonisation and is thus more durable.[3] It also protects against insects.

Contemporary architect Terunobu Fujimori works with yakisugi.[4][5]
