Yakusugi cedars are distinguished as "Kosugi" and "Yakusugi" based on the density of their annual rings, and they are not considered Yakusugi unless they are over 1000 years old.
Due to the climate of Yakushima, the trees grow slowly and gradually. This is why they develop such dense annual rings.
The dense annual rings reveal a magnificent figured grain when viewed in the direction of the flat grain.
A memorial tablet made from Yakusugi cedar is truly a masterpiece of nature, created over countless years.
