The film examines how urban dwellers live alone but still interact with others in modern cities. This trend of solo living challenges traditional notions of home and its implications for urban society. The reasons for living alone are clear—social changes, flexible work, new demographics, more wealth, and different gender roles—but the impacts on urban space and social structure are unknown. The film explores this phenomenon through stories of individuals in singleton homes and their extended domestic sphere. The film features architect Takahashi Ippei and sociologist Yoshikazu Nango, who share their perspectives on single spaces in Tokyo.

If living alone is our new reality, what should it look like?
