Located on Amami Island in southern Japan, this self-sufficient house was designed for a family of four to live comfortably without relying on the power grid or mechanical air conditioning. Rooted in the local landscape and cultural memory, it reinterprets traditional living through a contemporary lens, embracing natural forces to achieve harmony with the environment. Grounded in passive design, it minimizes active systems, integrates climate and culture, and opens to the community—quietly redefining what it means to dwell today.
