In this article, we analyze the ways by which we tackle social problems in our developed society. We focus on solutions met by recombining existent social arrangements, or redesigning society. We single out examples from redesigned medical care, public health, and nursing care by local partnerships and discuss the importance of redesigning society by changing a small number of “variables.” We draw on an example of “Local Community Areas” by architect Riken Yamamoto, illustrating how the “Public-Common-Private” triad is a key variable in redesigning communities. We also introduce a case study of medical care, public health, and nursing care partnerships in the City of Kitakyushu and find that the key variable is again the “Public-Common-Private” partnership.
