Since Keyaki has a beautiful grain and strength, it is said that keyaki is the best Japanese hardwood used for commercial lumber. Compared to before, the amount of trees with a big diameter is decreasing, so the price is rising. However, Keyaki is relatively easy to obtain. Keyaki was used for its strength in the past, but now people mainly use Keyaki for its elegant and beautiful appearance. Keyaki is considered a premium wood just like Hinoki.
