ユーカリ42-01F Eucalyptus wood is a highly practical material characterized by its bright, natural color and clean, straight grain.
It offers a good balance of hardness and strength and is relatively resistant to warping and cracking, making it widely used for everyday wooden products, crafts, and tools.
It has a smooth texture to the touch and allows for precise workmanship, which is another of its key advantages.
With proper finishing, it develops a natural luster and a neat, refined appearance.
Its understated, even grain does not overpower the design and blends easily with other materials, making it suitable for a wide range of products in both Japanese and Western styles.

“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.
