"Kaya" is regarded as one of the best materials to make Go and Shogi boards, because of its good sound and feel when placing the stones, moderate elasticity, beautiful grain, color, gloss and luster, and aroma.

"Hyuga kaya" is a special type of close-grained Japanese nutmeg tree grown and harvested in a mountainous area in the southern part of Kyushu, Japan.

The reason why Hyuga kaya from Miyazaki Prefecture is of the highest quality is because of the natural environment in which the tree grows.
The climate in southern Kyushu and the Miyazaki area has relatively big temperature differences between daytime and night time, a lot of rainfall, and strong direct sunlight, all of which help trees to produce clear-grain grains.
The wood grows on rocky terrain and requires several hundred years to grow into a tree large enough to be used as Go board material.
This is why it is considered a top-quality product, due to its rarity as well as its wood quality.
The grain of the wood is very fine and dense, so it rarely causes warpage or distortion.

Hyuga kaya boards are used in various title matches and famous tournaments.
The sound of the placing of stones on the board is very clear. Moreover, as it is used over the years, it will take on a refined candy-colored luster, further enhancing its maturity.
