Made from sustainably harvested Japanese cedar, known as “sugi” in Japan, Sugi Unoiled is a versatile, carbon-negative ceiling and cladding product. 

Sugi Unoiled's light weight and color, subtle aroma, and natural resistance to fungus, insects, borers, and fires make it ideal for both interior and exterior applications.

A ubiquitous building material in Japan, sugi remains rare in North America despite having a finer and more figured grain than its American cedar counterparts. These natural qualities are further enhanced by Nakamoto Forestry’s expert log production, grading, and millwork and commitment to sustainable harvesting practices as demonstrated by their PEFC certification and pursuit of EPD and CFP certification (coming in 2025).

As the primary distributor of authentically milled sugi wood in North America, Nakamoto Forestry offers Sugi Unoiled in three profiles—15mm, 35mm, and 48mm—to support a range of applications from paneling and flooring to cabinetry and furniture. Sugi Unoiled is available in select grade, which includes knots, and premium clear grade, which is knot-free. When left unoiled, as is typical in Japan, sugi develops an elegant patina. However, standard stains and coatings can be applied to add color and consistency if desired. Nakamoto Forestry also offers a silver weathering stain, which develops a bleached coastal patina inspired by the Cape Cod gray aesthetic.
