Set within the forests of Karuizawa, this project explores architecture as a device that carefully modulates the relationship between human and nature.
Developed over nearly a decade through continuous collaboration between client, builder, and architect, the building forms part of a dispersed landscape that includes dog-friendly facilities, open lawns, and training spaces.
Rather than dissolving the boundary between interior and exterior, the project subtly controls it. Large openings on both sides allow the forest to visually pass through the building, while maintaining a delicate sense of enclosure. The architecture does not disappear into nature; instead, it creates a calibrated distance that allows people to perceive it more consciously.
A three-layered roof introduces soft daylight through high clerestory openings, producing a quiet and transparent spatial atmosphere. The structure is composed of simple timber elements using widely available materials, yet carefully arranged to achieve both structural clarity and spatial richness.
By minimizing the use of concrete and metal connections, and relying on local craftsmanship, the building demonstrates how modest means can generate a refined environmental response.
This project proposes architecture not as an object, but as a medium that reshapes how we experience proximity, distance, and coexistence with nature.
