Japanese Cedar (Sugi)
Cryptomeria japonica • Softwood
Grain Pattern
Typically very straight and uniform; fine to medium texture. Growth rings are usually distinct and can produce a decorative cathedral pattern on flat-sawn surfaces.
Color Description
Heartwood is typically reddish-pink to reddish-brown, sometimes with dark brown or black streaks. Sapwood is a pale yellow to white. It has a beautiful natural luster and tends to darken/mellow with age.
Hardness Rating
320 lbf (Very Soft)
Durability Rating
Durable to Very Durable regarding rot resistance; historically valued for its ability to withstand decay in exterior conditions, though heartwood is most resistant.
Common Uses
Traditional Japanese construction, temples, shrines, barrel making (sake tubs), panelling, interior trim, fencing, and light furniture.
Geographic Origin
Native to Japan and southern China; widely cultivated as a timber tree in East Asia and parts of Europe and North America.
Market Value & Sustainability
Estimated Market Value
Approximately $4.00 - $8.00 per board foot depending on grade and presence of knots (clear vertical grain commands a premium).
Wood Age Estimate
The standing tree shown exhibits mature, peeling bark and thick girth, likely between 40 to 80 years old based on bark texture and branching patterns.
Sustainability Status
Not listed in CITES or the IUCN Red List of Threatened Species; highly sustainable due to extensive plantation management, particularly in Japan.
Workability
Very easy to work with both hand and machine tools. It planes to a high natural shine, but because it is very soft, it is prone to bruising and indentations during handling.
Notable Features
Distinctive resinous, spicy fragrance that persists for years; light weight; high tannin content which can cause dark staining if it comes into contact with iron fasteners.
Finish Recommendations
Traditional 'shou sugi ban' (charring), natural oils, or light clear lacquers. Heavy film finishes are often avoided to highlight the natural scent and texture.
Identification Confidence
High. The distinctive reddish, fibrous, peeling bark ('shreddy' appearance) and branching structure are classic indicators of Cryptomeria japonica.
