欅36号 Keyaki (Japanese zelkova) is one of Japan’s most prestigious hardwoods, prized for its bold, beautiful grain and outstanding durability.
Its clearly defined growth rings and dynamic figuring give each piece a unique and expressive appearance.
Hard and resilient, with excellent resistance to impact and wear, it is an ideal material for items meant for long-term use, such as Go boards, Go bowls, Shogi boards, and fine furniture.
Another distinctive appeal of keyaki is its aging character—the color deepens and the surface gains a richer luster with continued use.

Keyaki is a refined wood that embodies both traditional Japanese character and a commanding presence.

“Moku” (figured grain) refers to distinctive, decorative grain patterns that appear on the surface of wood.
Unlike ordinary straight grain or annual ring patterns, figured grain is created by irregular changes in the wood’s structure that occur naturally during growth, and is often described as nature’s own artwork.
Common types of figured grain include tiger figure, blister figure, burl figure, and bird’s-eye figure, each showing unique expressions such as stripe-like patterns, bubble-like clusters, or complex swirls formed around knots and burls.
Moku figured grain
Because figured grain cannot be artificially reproduced and results from natural, individual growth conditions, no two patterns are exactly alike, allowing you to enjoy truly one-of-a-kind beauty.
Another appealing feature is how its appearance changes depending on the angle of light, creating a sense of depth and movement.
Due to its rarity and visual richness, figured wood has long been prized for high-end furniture, musical instruments, tea utensils, and fine crafts. In the world of Go and Shogi, it is also used for boards, bowls, and piece boxes, adding special value to each item.
Figured grain, shaped by nature itself, brings unique character and refined elegance to wooden works.
