Modern cities face a thermodynamic paradox: economic growth accelerates material entropy, yet prevailing urban sustainability paradigms overlook the fundamental constraint of irreversible resource degradation. This linear, resource-intensive growth model has pushed urban metabolism to a critical threshold where cities consume 75% of global materials and produce 70% of CO₂ emissions. Yet, a framework for systematically mitigating this entropic decay remains absent from mainstream urban planning. This study seeks to bridge this gap by analysing Japan's systematic institutionalisation of Georgescu-Roegen's entropy law through a multi-scalar governance framework, with Kawasaki's Eco-Town as a primary case study. We demonstrate how Japan's hierarchical approach has achieved remarkable outcomes by implementing three core mechanisms across distinct scales: (1) Macro-scale policy that establishes Extended Producer Responsibility (EPR) frameworks and mandatory, high-level recycling targets, acting as de facto national entropy budgets, (2) Meso-scale spatial optimisation through municipal industrial symbiosis that minimises transport and processing dissipation; and (3) Micro-scale citizen co-design programmes that cultivate low-entropy behaviours and ensure high-fidelity compliance. This integrated framework enables high-value material loops, evidenced by an 85% PET recycling rate, a 99% construction material recycling rate in Kawasaki, and a national landfill rate of 0.8%. Kawasaki’s per capita waste generation of 730g/day—the lowest in Japan—stands as a key metric of micro-scale efficacy. However, irreducible thermodynamic frontiers persist, particularly regarding critical material recovery, where lithium and silver recovery remain below 1% due to fundamental concentration limits (NERR < 1). Through integrated policy analysis, we argue that while perfect circularity is thermodynamically unattainable, strategic multi-scalar entropy reduction offers a replicable blueprint for aligning urban development with biophysical reality.
