Koufuen 1986 stands as a significant example of 1980s welfare architecture in Kawasaki, Kanagawa Prefecture. Completed in 1987, this facility combines a special nursing home with day service center functions, addressing the growing needs of Japan's aging society. Designed by architect Tomonaga Yutaka and Form System Design Laboratory, the building integrates practical care spaces with thoughtful architectural design. The project reflects the period's commitment to creating dignified environments for elderly residents while maintaining operational efficiency for caregiving activities.
