Sagino Miya Garden House is a residential complex completed in 1974, located in Nakano Ward, Tokyo. Designed by Sumitomo Realty and Development's Architecture and Technology Division in collaboration with Ebisu Construction, this structure exemplifies mid-1970s Japanese apartment architecture. The building showcases the era's approach to residential design, featuring a garden house concept that integrates outdoor spaces within an urban residential setting. As a notable example of collective housing from this period, it reflects the architectural practices and living standards of post-war Japan's economic growth era. The project represents an important case study for understanding residential architecture development during the 1970s in Tokyo's suburban areas.
