The Kunio Maekawa Residence is the private home of Kunio Maekawa, one of Japan's most influential modernist architects, designed in 1942. Designated as a Tokyo Tangible Cultural Property, the residence is located within the West Zone of the Edo-Tokyo Open Air Architectural Museum. The building was constructed under the severe architectural restrictions of World War II. To overcome these constraints, Maekawa utilized ingenious design techniques to create a sense of spaciousness despite a minimal building footprint. The most defining features are the central living room with its soaring open atrium and the loft-style second floor situated above it.
Kunio Maekaya played a pivotal role in the history of modern Japanese architecture. The year of this residence's construction, 1942, was marked by harsh social conditions and wartime-era regulations. Facing strict limits on building area and materials, Maekawa presented a unique solution to achieve a rich, comfortable living space. This residence is more than just a private home; it is a vital historical document where the constraints of the era met the visionary philosophy of a great architect. Today, it is preserved and showcased as part of the Edo-Tokyo Open Air Architectural Museum, serving as an important relic that traces the development of modern Japanese architecture.

The most remarkable feature is the central atrium structure. By emphasizing verticality within a limited footprint, the design creates an extraordinary sense of openness. Additionally, the loft-style second floor showcases pioneering ideas that resonate even with contemporary residential design. The functional, compact design—a direct response to wartime limitations—combined with the clean, geometric lines characteristic of Modernist architecture, makes this a must-see for anyone interested in architectural history.
As the Edo-Tokyo Open Air Architectural Museum is a vast outdoor site, the scenery changes beautifully with the seasons. To fully appreciate the architectural beauty of the Maekawa Residence, a visit on a clear, sunny day is highly recommended. Visiting during bright daylight hours allows you to observe how light interacts with the interior space and enhances the dramatic effect of the central atrium. Surrounded by nature, the residence is particularly beautiful during the seasons of fresh greenery or autumn foliage.
The primary activity here is the deep observation of architectural details. Visitors can witness firsthand the structural ingenuity, the use of materials, and the design philosophy used to maximize a constrained space. By exploring the other structures in the Edo-Tokyo Open Air Architectural Museum—such as traditional Japanese houses and Western-style mansions—you can gain a comprehensive understanding of how Japanese architecture has evolved through different historical eras.
The Kunio Maekawa Residence is located in the "West Zone" of the Edo-Tokyo Open Air Architectural Museum. This zone houses several significant buildings that convey the culture of modern-era residential architecture, including the Tokiwadai Photo Studio, the Mitsui Hachiroemon Residence, the Den-en-chofu House, and the Koide Residence. Walking through these sites allows for a systematic exploration of the diverse housing forms that emerged during Japan's modernization. Since the museum grounds are quite large, please plan your route accordingly.
Because the museum grounds involve significant walking, we recommend wearing comfortable walking shoes. When entering historical buildings, please strictly follow the rules to protect the cultural assets.
