5.8-sun Go Floor Board – Kyushu Kaya, Single-piece, Inner-heart cut

Material

This floor board is made from Kyushu Kaya and crafted as a single-piece, inner-heart cut board.
Kyushu Kaya refers to kaya wood grown in Kyushu, Japan.

An inner-heart cut board is made from the inner side of the log, where the growth rings form a cohesive and continuous pattern.
This construction preserves the natural structure of the wood across the full surface.

Thickness and Playing Response

The board measures 5.8-sun in thickness.
For a floor board, this provides a substantial depth and presence.

The weight and density contribute to a stable playing environment.
The tactile response when placing stones is firm and controlled, reflecting the material and thickness rather than artificial adjustment.

Such a specification may suit those seeking a more formal playing setting.

Included Accessories

The following items are included:

• Protective cloth cover

• Paulownia wood storage box

The paulownia box is intended for storage and protection.
Paulownia wood is traditionally used in Japan for its light weight and humidity-regulating properties.

Consideration

A 5.8-sun single-piece floor board represents a full-scale playing specification.
