Yakusugi: Sugi Grain and the Long Life of Yakushima’s Forests
WOOD DICTIONARY
The name yakusugi brings together the forests of Yakushima and a long passage of time. Botanically it is sugi, but the special name refers to where it grows and its age. In veneer, rather than a complete image of the great tree, we enjoy the grain preserved in a small section of its wood.
The photographs are examples of the color and grain associated with each wood or figure. Every piece of natural wood is different; the sheet you receive will not have exactly the same color or grain as the photographs.

Yakusugi is not a separate species
In general, naturally growing sugi on Yakushima more than a thousand years old are called yakusugi, while younger trees are called kosugi. This is not a botanical distinction like that between hinoki and sugi, but a name expressing place and a long growing history within the same species. Remembering that it is a little different from a species name helps when looking at timber labeled yakusugi.

Slow growth expressed in the grain
The Japan Tourism Agency’s account of yakusugi describes the relationship between Yakushima’s growing environment, slow growth, and closely spaced growth rings. Yet even in a long-lived tree, not every part has growth rings at the same intervals. Curving grain and changes of color mean that small surfaces differ depending on where they were cut.

MORI KOUGEI offers yakusugi as figured A4 veneer. The layering of fine lines and changes in their flow invite you to consider the pattern’s orientation. The photographs are individual examples, not a promise of identical fineness or pattern. Even when using it in just part of a finished piece, there is pleasure in choosing which part of the sheet you receive to show. MORI KOUGEI: Yakusugi A4 Veneer
Fallen trees help the next forest grow
On Yakushima, new sugi can grow on fallen logs and old stumps, processes known as regeneration on fallen wood and stump regeneration. A great tree’s fall is not simply an end: it can provide a foundation for the next tree. The appeal of yakusugi lies not only in age but in these connections between forest generations. This forest story does not, however, explain how an individual sheet offered for sale was sourced. Japan Tourism Agency and Yakushima Environmental Culture Foundation: The Ecology of Yakusugi
Yakusugi’s character in a thin decorative material
The A4 product is 210 × 297 mm and approximately 0.25 mm thick, with a washi-paper backing. It adds grain to a supported surface, such as a box lid, decorative panel, or marquetry design. To make the most of the natural color and figure, check that application and finishing methods suit your substrate. Stories about the age or durability of giant trees should be considered separately from the handling of a thin sheet. MORI KOUGEI: Yakusugi A4 Veneer
