Traditional architectural craftsmanship in Japan faces significant challenges due to modernization andindustrialization. While most single-family homes now rely on post-and-beam construction with pre-cutjoinery and metal connectors, some small carpentry firms continue to uphold traditional hand-carvingtechniques. This study examines Firm S, a carpentry firm in Shiga Prefecture, investigating how itpreserves these woodworking traditions while adapting to contemporary needs. Through participantobservation in construction projects, this study identifies key adaptations in three main structuralcomponents—walls, roofs, and foundations—when compared to the vernacular farmhouses of the region.Interviews with local practitioners were conducted to understand the reasons behind these adaptations, aswell as their motivations for preserving woodworking traditions. In newly constructed wooden houses,cedar board walls, gable roofs with metal panels, and reinforced concrete foundations have largelyreplaced the mud walls, tiled roofs, and stone foundations of vernacular houses. Key factors driving theseadaptations include legal restrictions, time and cost efficiency, and aesthetic preferences. Firm S seesthese structural adaptations as necessary compromises to sustain woodworking traditions—particularlyhand-carving techniques—while remaining competitive. More importantly, the firm addresses two majorchallenges in Japan: the short lifespan of contemporary wooden houses and unsustainable forestrypractices. Traditional wooden houses can last for centuries thanks to hand-carving techniques that enablethe replacement of damaged structural components and the customization of joints to accommodatetimber’s natural shrinkage. By promoting longevity in wooden houses, Firm S seeks to balance timberconsumption with forest regeneration. Efforts are also made by exclusively using locally sourced lumberand participating in reforestation activities. For Firm S, preserving woodworking traditions is more thana technical decision of architectural authenticity—it is a moral and ecological responsibility of fosteringa symbiotic human-nature relationship. By doing so, the firm not only preserves traditional craftsmanshipbut also advocates for a more ecologically responsible approach to contemporary construction.
