Highest Quality Hyuga Kaya Board Processed by Traditional Craftsmanship

Clear grain patterns can be produced only when trees are grown in extreme temperature differences with a lot of rainfall and under strong direct sunlight. Especially it is planted at infertile land and the tree grows very slow, tree rings are very close each other.
As Hyuga Kaya wood is planted at rocky mountains and grown under such severe climate, it can produce close tree rings and very fine grain patterns.
(Note: 'SUN' is an old Japanese scale unit. 1sun = approx. 3cm.)

You may find small knots, burrs, rolled-in bark as all these products are made of natural trees.
