Shin-kaya wood, also known as "new kaya", is a spruce wood grown mainly in North America, which is different from Japanese kaya.
Spruce wood is widely used because it grows straight, is odorless, has low oil content, is easy to process, and is in good supply, making it relatively inexpensive to produce Go/shogi boards.
Spruce board is sold at an affordable price but it has a similar grain and color to honkaya but is not as high quality as honkaya wood.
The quality of the spruce is comparable to that of honkaya or Hyuga kaya, but it is less prone to deformation and cracking.
Spruce wood is also used as SPF (spruce, pine, fir) material for furniture and building materials, but unlike kaya wood, it shows significant deterioration over time, such as changes in wood color, and has a shorter life span.
