# Century-old Japanese cedar transformed into flat-pack furniture Traditional forestry meets modern design in this sustainable furniture collection. - **Source:** [design archives | designboom | architecture & design magazine](https://brifing.si/source/11868f8d-1e20-41ac-bc2d-8c5af32d721b) - **Published:** 2026-07-13 - **Topic:** [Design & UX](https://brifing.si/c/design) - **Original article:** - **On Brifing:** https://brifing.si/s/a2e2a9c7-0aa1-4bfd-abe6-cdb1b5c84866 ## Traditional material, modern design The FLAT/FORM collection uses 15mm-thick veneer panels from Japanese cedar trees over 100 years old. Designer Satoshi Itasaka combines traditional Japanese construction techniques with flat-pack systems to create a sustainable production model for furniture. ## Assembly system inspired by origami Drawing from Japanese origami and kimono traditions, the collection transforms flat surfaces into three-dimensional furniture forms. Components are assembled with bolts and nuts without adhesives, allowing pieces to be returned to a completely flat state. ## Solution for sustainable forestry The project addresses Japan's declining timber demand and aging forestry sector through innovation. Cedar from selectively harvested and replanted forests in Miyazaki gains long-term value through thoughtful design applications. ## Repairable and modular design Adhesive-free construction enables easy replacement and repair of components. This approach extends product lifespan while reducing packaging volume and material waste during transportation. ## Gateway to international markets Using veneer panels helps overcome regulatory barriers to Japan's raw timber exports. As processed products, the furniture pieces expand the global presence of Japanese forestry beyond local markets. ## The future of furniture design The FLAT/FORM project presents a new perspective for the furniture industry through sustainable materials, functional design, and traditional craftsmanship. This value-adding approach to local resources serves as inspiration for other sectors. ## Sources covering this story - https://www.designboom.com/design/century-old-japanese-cedar-flat-pack-furniture-collection-flat-form-satoshi-itasaka-h220430/ — --- _Summary written by Brifing from the original reporting.
