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.
There are three types of kaya trees: "Hyuga Kaya" which is grown and harvested in a mountainous area in the southern part of Kyushu, Japan, "Japanese-grown honkaya" which is grown in other areas of Japan, and "Chinese-grown honkaya" which is mainly grown in Yunnan Province, China.
Generally, Japanese-grown honkaya is said to be better than Chinese honkaya in terms of quality.
The main difference between Japanese and Chinese kaya is the wood quality, caused by the natural environment where the tree was grown. Japanese kaya is usually lighter and more yellowish in color and has a unique wood aroma.
Depending on your preference, Japanese kaya is generally more highly valued than Chinese kaya, and the value and price of Japanese kaya tends to be higher due to the rarity of the wood.

In order to make a one-piece Go/Shogi board or board with legs, it is necessary to get a large tree between 200 and 800 years old.However, since logging is now prohibited in many forests in Japan, large-diameter kaya wood is almost impossible to find on the market.
The procurement of kaya is becoming more and more difficult and the Japanese honkaya Go board is getting rarer year on year.
