All Go stones, Go boards, Shogi pieces, Shogi boards, Go bowls, etc. are made using natural materials.
For this reason, some products may present defects such as flaw, stain, crack and/or wood knots, or damages caused at the time of manufacturing and/or storage, and thus they cannot be sold at full price.
We do not sell any product with significant defects. We may sell some products with minor defects as "off-spec products" at a discounted price upon confirmation that customers are duly aware of any defects in advance.
We try our best to describe the condition of any defect as precisely as possible using pictures and text.
Please order items only after checking and accepting the condition of defects. Thank you.
*'Defects' refer to any scratch and flaw.

"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.

"Ten-masa" cutting style has masame (straight grain) only on the top surface of the board.
The bottom surface has itame (flat grain).
The general masame boards belong to this type.
The top surface is beautifully finished so the ten-masa board is highly valued.

However, when the material itself is too small in diameter to make a 1-piece composition board, or when it is impossible to make a board from a 1-piece composition board for various reasons, boards are sometimes made by joining pieces of wood together.
A board made in this way is called a “Tsugi-ban (composition board)” or “hagi-ban (composition board)".
There are several types of composition boards, and the fewer the number of pieces of wood grafted together, the less variation there is in the color and grain of the wood, and therefore, the more valuable the board is.
When manufacturing a composition board, we combine materials whose wood color and grain are as close as possible to each other so that there is as little discrepancy as possible.
Then, the joints are calculated so that the scale is placed over the joints as much as possible. (In some cases this is not the case.)

In fact, we spend more time and effort to produce a composition board, which is slightly less valuable than a 1-piece board.
The composition board also has an advantage: since multiple pieces of material are joined side by side, each piece is narrower and less prone to warping.
