We propose key performance indicators (KPIs) based on the Gross Social Feel-Good Index to evaluate a smart sustainable city and report the results of a field trial in a city located almost at the center of the Tokyo Metropolitan Area. We developed KPIs based on the following concepts: (1). The triple bottom line is the basic evaluation criteria; (2). The same unit is used for every evaluation criterion; (3). The KPIs can be used to assess a diverse range of smart sustainable cities with different goals. With the proposed KPIs of smart sustainable cities, indicators are divided into four layers for simplicity: the triple bottom line and “satisfaction” lie in the first layer. Since the notion of “society” is broad, it is further split into “safety”, “health”, and “comfort”, which are positioned in the second layer. The third layer includes indicators such as “information security” and “ubiquitous society” from the perspective of information communication technology (ICT). We conducted a trial evaluation by applying the proposed KPIs to individual ICT solutions of “Internet Protocol announcements”, “Wi-Fi around the station” and “information transmission and control” which have already been installed in a smart sustainable city.
