About Sugi Japanese Cedar

Sugi Japanese Cedar (Cryptomeria) is a soft wood that works easily but dents readily, with a Janka hardness of 401 lbf (1784 N) and a density of about 0.38 g/cm³. It originates from other.

With radial shrinkage of 1.8% and tangential shrinkage of 4.2% (a T/R ratio of 2.33), it is prone to distortion if dried or detailed carelessly, due to its high tangential-to-radial shrinkage ratio. Its fiber saturation point is around 30%, below which the wood begins to shrink and move as it dries.
