The Japanese Cedar Flat-Pack Collection: Design Rooted in Sustainability

A table, four chairs, and a shelving unit crafted from Japanese cedar mark the launch of Takumi Hoshino's collection in September 2023. This furniture repurposes cedar trees discarded during forestry management in Japan. Sourced from the Arashiyama foothills, the wood is harvested by cooperatives to alleviate overcrowding in mid-20th-century monoculture forests. The aged wood, between eighty and one hundred years old, arrives at Hoshino’s workshop with visible knots and insect trails, all preserved under a matte tung oil finish.

“Cedar has long been undervalued in furniture-making due to its softness,” Hoshino said during an interview at his studio. “But with careful lamination techniques and proper reinforcements, it becomes workable for load-bearing designs.” His collection employs dowel joinery and custom metal brackets from a blacksmith collective in Osaka, ensuring stability while maintaining flat-pack convenience. Each item ships in recyclable boxes no thicker than 6 cm.

Hoshino’s focus on waste reduction sets his work apart. Offcuts transform into smaller components like stool legs and drawer handles. Daily collected sawdust fuels local biomass cogeneration plants. “The goal,” Hoshino added, “is a system where nothing leaves the workshop as waste.”

The collection features rectilinear profiles and clean edges that highlight the wood's natural grain. The standout piece, a dining table measuring 180 cm by 85 cm, showcases a single central support beam, maximizing legroom and emphasizing the laminated cedar’s contrasting color bands. Priced at ¥240,000 ($1,600 USD), the table appeals to urban buyers prioritizing function and ecological impact.

Debuting at the Tokyo International Furniture Fair from 13–17 September 2023, the collection attracted attention for its focus on local production cycles. Keiko Murata, a curator at 21_21 Design Sight, noted, “Japan’s monoculture forests pose a challenge, but projects like Hoshino’s show how these materials can be reintegrated into ecosystems of usage.”

Historically, cedar played a crucial role in Japanese architecture, from temple pillars to shoji frames. Its use declined in the 20th century, overshadowed by imported hardwoods and synthetic materials. Hoshino’s work reclaims cedar’s significance, merging traditional woodworking with modern flat-pack design.

Collaborating with Forest Renewal Japan, Hoshino contributes a percentage of sales to sapling planting in logging-affected areas. Using local timber reduces transportation costs—cedar from Arashiyama travels less than 25 km to his studio.

The collection resonates with eco-conscious buyers in urban centers like Tokyo and Osaka. Takayuki Yamamoto, a critic for KINOKO: Design Futures, praised its balance of simplicity and depth, calling it “an antidote to fast furniture.” However, concerns about scalability persist, particularly regarding the custom flat-pack brackets that increase costs compared to standardized designs.

Hoshino remains focused on creating a system that honors material origins while addressing environmental challenges. He hinted at future collaborations, including smaller items like trays and coasters made from cedar veneer offcuts.

The Japanese Cedar Flat-Pack Collection challenges traditional furniture value, urging a reflection on the landscapes from which it originates. In Hoshino’s studio, the cedar’s faint aroma lingers, a reminder of its roots in Kyoto’s forests. Modest in scale, the collection points toward a design philosophy that values forests as much as furniture.
