Rough Sawn Kiln Dried (RSKD) Lumber
Our rough sawn kiln dried lumber provides a high degree of versatility and quality for different applications. It's a reliable choice for elegant cladding or siding, durable window and door frames, or bespoke furniture.
Hinoki’s natural resistance to moisture and decay is ideal for wall panelling, ceiling materials, and high-humidity environments like saunas. Sugi's lightweight nature and distinctive grain pattern make it prefect for exterior siding, outdoor structures, and decorative interior applications.

Thanks to the precision of Japanese craftsmanship and kiln-drying processes, our lumber maintains dimensional stability and durability. It’s perfect for traditional uses like fencing and framing, and for niche applications like movie set construction and wooden boat building.


Its aesthetic appeal and workability ensure excellent results in flooring and other interior finishes, bringing warmth and sophistication to any space. You will use a durable material that’s been proven with iconic structures and everyday applications for centuries.
To ensure optimal value for both sawmills and buyers, we focus on standard Japanese lumber dimensions that don't require custom work. But please don't hesitate to contact us for custom inquiries. We also offer S4S (surfaced on four sides) timber for projects requiring a smooth, ready-to-use finish.
Whether you're a distributor, builder, or designer, we're ready to help you explore the possibilities of rough sawn Japanese lumber.
