Revitalizing the Historic Migiwa House Atelier: A Bold Reconstruction Plan

On October 28, 2025, a special press event will unveil an ambitious renovation project for the Migiwa House Atelier, a designated cultural asset in Nakano, Tokyo, originally completed in 1934. This endeavor, spearheaded by Keyman Corporation under the leadership of its President, Toshio Katayama, represents a significant evolution in the approach to preserving modernist architecture in Japan. The Migiwa House Atelier is a rare example of pre-war wooden modernism, designed by architect Isamu Yamawaki, who was influenced by the Bauhaus philosophy during his studies in Germany.

Architectural Significance

The atelier was built as a shared studio and residence for the renowned painter couple, Kotaro and Setsuko Migiwa. Its design, characterized by a straightforward rectangular form and large windows on the southeast facade, embodies a unique synthesis of the client’s artistic sensibility and the principles learned by Yamawaki. The interior features a double-height studio space constructed with a spiral staircase, contributing to its distinct aesthetic and functional qualities. This structure stands as a reminder of the cultural activities of the early Showa period, making it essential to preserve its legacy.

Planned Renovation

The renovation will integrate modern features while preserving the building's distinctive characteristics. It aims to address the issues of aging structures, posing important questions about how society can retain modern architecture while ensuring it remains relevant for future generations. The plan will focus on transitioning from static preservation and exhibition to dynamic preservation and active utilization, reflecting a shift in conservation philosophy. This symbolic project seeks to exemplify how cultural assets can coexist with contemporary needs, allowing for their ongoing relevance.

Event Details

The press conference will take place at the Migiwa House Atelier on October 28, 2025, at 14:00, providing a platform for the announcement of the renovation details. Media representatives will have an exclusive opportunity to hear insights from key figures involved in the project, including Professor Jutaro Takahashi from Kanagawa University, whose expertise in architecture offers valuable perspectives on the preservation of historical structures.

Broader Impact

The renovation comes at a time when the preservation and revitalization of modern architecture are pressing issues across Japan, particularly as the centenary of the Bauhaus movement approaches. Keyman Corporation believes this renovation project will set a precedent for how modern buildings can be adapted rather than restored to their original states, enhancing their cultural value without detracting from their historical significance. The connection with Tokyo Cultural Week, taking place from October 25 to November 3, 2025, further underscores the initiative's commitment to raising public awareness around cultural heritage and its contemporary implications.

Future Aspirations

The Migiwa House Atelier is not only about retaining a piece of history; it is about breathing new life into it. The incorporation of cutting-edge techniques in restoration showcases a forward-thinking approach toward cultural preservation. As society grapples with the challenge of maintaining the old while innovating for the future, the Migiwa House Atelier stands as a beacon of possibility, demonstrating that heritage can thrive dynamically within the context of modern life.

Keyman Corporation, with over three decades of experience in civil engineering and architecture, is committed to fostering the value of urban spaces. Following the renovation of the Migiwa House Atelier, the company also plans to enhance the neighboring Casa Bianca building, consolidating their REDO project, which focuses on the seismic retrofitting and renovation of older structures. This holistic approach to urban development reflects a proactive stance on cultural asset preservation, encouraging a more inclusive narrative about architectural heritage.
