This study compared the structure of the smart city reference architecture with that of the regional-emergence platform. The regional-emergence platform is encompassed in the city operating system (OS) as a group of regional information platform functions. We hypothesized that this structure enables the intermediate support system (human platform) and regional platform (site creation) to play their roles in urban management, therewith configuring the smart-city design requirements. Based on this hypothesis, we examined a case of smart city implementation in Kakogawa City, Hyogo Prefecture. We confirmed that a bottom-up approach is more effective, as issues could be resolved for individual services as a process of horizontal development.
