Koyama Kaya

The oil extracted from the seeds of the Chinese hackberry trees that grow naturally on Mount Koya can be used for lighting, which is why many of these trees are planted at shrines and temples throughout the country. Mature trees can reach a diameter of 2.5 meters, but they grow slowly and are difficult to cultivate. The wood is dense and uneven in texture, featuring a beautiful pale cream color, a unique luster, and a sweet fragrance. It is said that hinoki wood possesses the mysterious property of restoring dents to their original state.
