Historical Building Restaurant Conversion in Japan: A Case Study of Washoku Itagaki
The article showcases Washoku Itagaki, a project transforming a 1938 house in Japan into a restaurant complex, blending tradition with modernity.
In the heart of Adachi City, Japan, the Washoku Itagaki Restaurant stands as a beacon of architectural ingenuity and culinary excellence. Spearheaded by Buttondesign architects and photographed by Masao Nishikawa, this project is a testament to the transformative power of Historical Building Restaurant Conversion in Japan. Completed in 2020, the restaurant has become a symbol of heritage preservation fused with modern design.


Preserving Cultural Heritage through Design
The Genesis of Washoku Itagaki
The journey of Washoku Itagaki began with a desire to save the "Former Itagaki Residence," a private house built in 1938, from being converted into an apartment building. This initiative to preserve the townscape's historical essence led to the creation of a unique dining establishment. The project, initiated in the summer of 2019, amidst the looming uncertainty of the coronavirus pandemic, reflects a deep commitment to architectural preservation and cultural sustainability.



Architectural Design and Vision
Under the leadership of lead architects Yuzuru Murakami and Kohei Kikuta, and in collaboration with local artisans from Kitasenju, the renovation embraced the building's historical elements while infusing contemporary design principles. The outcome is a harmonious blend of old and new, showcasing the versatility and potential of historical building restaurant conversion in Japan.



A Culinary and Community Hub
The Concept Behind the Conversion
The conversion of the former Itagaki Residence into a cluster of three distinct dining experiences – Washoku Itagaki, TSUJI - Tea and Shaved Ice, and BAR - BA – exemplifies the innovative approach to utilizing historical spaces for modern purposes. This project not only revitalizes a significant architectural landmark but also reinvigorates the local community and its connection to the town's history.


Impact on the Community
The establishment of Washoku Itagaki and its sister outlets has been a catalyst for community engagement and urban renewal. By creating a space where people of all ages can gather, enjoy traditional Japanese cuisine, and partake in cultural activities, the project has restored the vibrancy to an area once bustling in the Edo period. It stands as a model for how historical building restaurant conversion in Japan can foster community ties and economic development.


A Beacon of Heritage and Innovation
Washoku Itagaki Restaurant, through its thoughtful design and community-oriented approach, illustrates the potential of historical buildings to serve as platforms for cultural and economic rejuvenation. As a pioneering example of historical building restaurant conversion in Japan, it sets a precedent for future projects aiming to balance heritage preservation with contemporary need.
