Japanese Cedar (Sugi) with Shou Sugi Ban finish
Cryptomeria japonica • Softwood
Grain Pattern
Straight, coarse grain with prominent cathedral figures in flat-sawn sections; features distinct growth rings with a high contrast between earlywood and latewood.
Color Description
Naturally light yellowish-brown heartwood, here modified via carbonization (charring) to a deep charcoal or near-black color. High points of the grain remain a lighter amber-brown, providing a high-contrast aesthetic.
Hardness Rating
320 lbf (Very Soft)
Durability Rating
Durable to Very Durable; the Shou Sugi Ban charring process further enhances resistance to decay, water, insects, and UV degradation.
Common Uses
Exterior siding/cladding, wall paneling, fencing, decorative interior accents, and modern furniture design.
Geographic Origin
Native to Japan (endemic), also widely cultivated in China and the Azores.
Market Value & Sustainability
Estimated Market Value
$8.00 - $15.00 per board foot (depending on the depth of charring and manufacturing process).
Wood Age Estimate
Modern processing; the charred surface appears newly applied (0-5 years) for contemporary architectural use.
Sustainability Status
Generally sustainable and widely available; not listed on CITES or IUCN Red List as endangered; frequent FSC availability.
Workability
Very easy to work with hand and machine tools due to low density. However, it is prone to denting because of its softness. The charred surface can be brittle and messy (soot) until properly sealed.
Notable Features
Distinctive spicy/cedar scent when cut; unique fire-resistance and pest-deterrence properties gained through the carbonization process; lightweight.
Finish Recommendations
Penetrating natural oils (such as Tung or Linseed oil) are recommended to seal the charred layer and prevent soot transfer while maintaining the matte texture.
Identification Confidence
High; the combination of the pronounced, wide softwood grain rings and the characteristic Shou Sugi Ban (carbonized) finish is highly specific to treated Cedar or Larch.
