Set in the rarefied alpine retreat of Karuizawa—long favoured by global elites including Bill Gates—this exceptional private residence is a collectible work of contemporary Japanese architecture.

Designed by world-renowned architect and designer Oki Sato, founder of the celebrated design studio nendo, the home exemplifies restrained innovation and deep respect for nature. Sato’s global portfolio includes collaborations with Hermès, Louis Vuitton, and Minotti, as well as landmark public works such as the Olympic cauldron for the Tokyo 2020 Olympics and the Japan Pavilion at EXPO 2025 Osaka-Kansai.

Known as “Wall House,” the residence sits on a distinctive long, narrow triangular site stretching 110 metres along the road. Its design masterfully balances openness and privacy: five parallel rows of architectural block walls act as visual filters, shielding the interior from passing traffic while framing serene views of the surrounding forest. Living spaces are delicately inserted between these layers, creating a rhythmic sequence of light, shadow, and greenery.

The structure is built using CO2-SUICOM blocks—an advanced low-carbon material that absorbs carbon dioxide, offsetting emissions generated during cement production—underscoring the home’s commitment to environmental responsibility without compromising aesthetic purity.

Single-storey, timber-structured, and meticulously detailed, this residence is not simply a home but an architectural artefact—ideal for collectors, design connoisseurs, or those seeking a discreet yet globally significant retreat in one of Japan’s most prestigious resort destinations.
