About House In Mise Private Home
House In Mise is a renovation of a traditional Japanese rural residence located in a river valley in Mitsuse, Saga Prefecture. The project restores the spatial clarity of the original timber structure while reconnecting daily life with the surrounding forest and flowing water. Carefully positioned openings, deep eaves, and layered transitional spaces allow light, shadow, and seasonal change to shape the interior environment. Locally sourced materials including cedar, hinoki cypress, reed, granite, and handcrafted shoji reinforce climatic compatibility and material authenticity.
Tomomi Omachi's House In Mise Private Home emerges from an architectural tradition that honors the dwelling as a carefully calibrated threshold between human habitation and natural landscape, a philosophy deeply embedded within regional building cultures where domestic architecture has historically negotiated climatic realities, material availability, and aesthetic sensibilities through vernacular forms refined across generations. This residential work demonstrates accomplished synthesis of traditional typological wisdom and contemporary spatial aspiration, evident in the deliberate preservation of the steeply pitched ceramic tile roof whose substantial presence and horizontal coursing establish immediate cultural legibility and visual grounding while providing practical weather protection and thermal performance suited to variable seasonal conditions. The compositional achievement lies particularly in the skillful layering of spatial zones and material expressions: the weighty roof volume providing protective enclosure and historical continuity, the warm timber-clad middle register offering textural richness and chromatic warmth through what appears to be clear-finished cedar or similar wood species whose visible grain patterns and natural coloration create living surface that will patina gracefully with exposure, and the extensively glazed ground level establishing transparency and spatial fluidity between interior domestic realm and exterior garden territory. The integration of traditional shoji-inspired translucent panels on the upper level demonstrates cultural memory operating through contemporary materials and construction methodologies, filtering light while maintaining privacy, creating soft interior glow visible from exterior vantage points that suggests inhabited warmth within. Technical facility appears throughout the precise detailing of glazing systems with slender dark-framed mullions maximizing transparency, the careful integration of cylindrical ventilation elements whose industrial materiality contrasts productively with vernacular roof forms, and the thoughtful cobblestone paving whose irregular coursing and tonal variation provide textural foundation grounding the composition. The garden integration reveals sophisticated understanding of landscape as essential architectural element rather than decorative afterthought: the verdant canopy framing the composition situates the dwelling within rather than against its wooded hillside context, while the foreground hydrangea cluster introduces seasonal chromatic accent and organic form as counterpoint to geometric architectural clarity. This work invites contemplation of how contemporary residential architecture might honor material authenticity, cultural continuity, and environmental sensitivity while providing spatial experiences suited to present-day domestic life, suggesting that tradition and innovation need not exist in opposition but rather can inform and enrich one another through thoughtful design synthesis. How might such careful attention to material character, spatial transparency, and landscape integration create dwelling experiences that nurture both physical comfort and psychological well-being through architectural means?
Press Kit
- Unique Properties
- This project is a renovation of a traditional Japanese rural house that reorients daily living toward forest and river through spatial layering, light modulation, and material authenticity. By retaining the existing timber structure and integrating engawa-like thresholds with locally sourced materials, it achieves environmental continuity, sensory depth, and long-term sustainability.
- Dimensions & Packaging
- Renovation of an existing traditional Japanese timber residence located in Mitsuse, Saga Prefecture, Japan. The project preserves the original wooden structural frame while introducing new timber openings, shoji-lined windows, and expanded terraces. Materials include local cedar columns, knot-free hinoki flooring, reed ceilings, and granite paving. Passive environmental strategies include cross-ventilation, deep eaves, and interior–exterior continuity to moderate seasonal climate conditions.

- Production Technology
- The project was realized through adaptive reuse of an existing post-and-beam timber structure, retaining approximately 80% of the original frame. Traditional Japanese carpentry and joinery were combined with precise contemporary detailing to recalibrate openings, deep eaves, and spatial thresholds. Locally sourced cedar, hinoki cypress, reed, granite, and handcrafted shoji paper were integrated to ensure climatic compatibility, material longevity, and seamless interior–exterior continuity.
- Design Challenge
- The primary challenge was reconciling contemporary living requirements with the preservation of a deteriorated traditional timber structure whose original spatial coherence had been lost through incremental alterations. Structural limitations, regulatory constraints on renovation, and climatic demands of a humid mountain valley required precise intervention. The project demanded selective demolition, careful structural repair, and the reinterpretation of traditional spatial principles to restore environmental continuity without erasing historical character.
- Project Duration
- The project is located in Mitsuse, Saga Prefecture, Japan, within a mountainous river valley in northern Kyushu. Design development and construction were carried out as a comprehensive renovation process, with the project completed in 2025 following an extended period of site analysis, design coordination, and on-site craftsmanship.
- Operation Flow
- The house is experienced through a gradual sequence between interior and nature. Large sliding openings connect the lounge, dining area, and guest spaces to terraces facing the river and surrounding forest. Light, wind, and seasonal landscape continuously transform the atmosphere throughout the day. The design encourages slow movement and quiet observation, allowing daily life to unfold in direct relationship with natural sound, light, and climate.
- Research
- Type of Research: Contextual architectural design research.
Research Objectives: To explore how traditional Japanese architecture can reconnect daily life with nature.
Methodology: Long-term site observation and iterative renovation design.
Data Collection and Tools: Climate analysis, spatial studies, material testing, and architectural drawings.
Participants: Architect and client collaboration over five years.
Results: A restored house integrating light, river, forest, and seasonal change.
Insights and Impact: Demonstrates how culturally rooted renovation can improve well-being and sustainable living. - Inspiration
- The project was inspired by traditional Japanese residential architecture, where light, shadow, and seasonal change shape daily life, and by the site’s forested river landscape in Mitsuse, Saga Prefecture. The client’s desire for refuge from urban intensity prompted a research-based approach to spatial layering, engawa reinterpretation, and material authenticity, integrating climate-responsive design and local craftsmanship to restore continuity between dwelling and nature.
