Smart city discourse predominantly focuses on growing urban centers, yet a growing number of regions worldwide face the opposite trajectory: depopulation, aging infrastructure, and the erosion of centralized services that underpin conventional disaster resilience. In Japan, “structural blank areas” (zones where public emergency services cannot physically reach) are expanding as rural communities shrink. This study argues that the principle of shared disaster safety must extend beyond smart cities to encompass shrinking societies, and proposes a socio-technical framework grounded in “Smart Shrinkage,” the strategic adaptation to population decline rather than futile resistance. Two complementary design concepts are introduced. Personal Infrastructure Space (PIS) redefines the minimum unit of resilience from centralized facilities to each individual’s immediate environment, ensuring autonomous energy supply, multi-modal communication via LEO satellites and LPWA networks, and decentralized data management even when macro-infrastructure is severed. Preliminary prototyping of core components has informed the technical specifications of this framework. Regional Life Care Stations (RLCS) function as phase-free community hubs comprising functional modules spanning energy, water, healthcare, logistics, and governance. These operate as productive assets for regional green and digital transformation during normal times while converting surplus capacity to life-saving functions during emergencies. The framework’s applicability is examined through the diverse geography of Miyagi Prefecture, comprising coastal, inland, and urban zones, to explore how inter-zonal resource synergies under the 4S (Smart Shrink for Sustainable Society) concept could create economic resilience in peacetime and dynamic mutual complementation during disasters, minimizing cascading failures. A trust-based decentralized governance mechanism enables autonomous resource allocation without centralized authority, which is critical when administrative functions contract alongside population decline. This study contributes a replicable socio-technical template demonstrating that smart shrinkage can transform demographic decline into an opportunity for resilient redesign, broadening the shared disaster safety agenda beyond conventional smart city boundaries.
