Fujisawa Sustainable Smart Town

Fujisawa Sustainable Smart Town is a residential redevelopment project located in an urban area of Fujisawa City, around 50 km away from central Tokyo. This project houses 1,000 households since the City Master Plan of Fujisawa City designated the area as a ‘’General Residential Area’’. Therefore, the actual land use is composed of mainly residential detached houses and moreover, there are green areas and commercial facilities for the residents and visitors. Overall, the buildings are quite new, since the redevelopment project started in 2008.

The redevelopment project is promoted by the Fujisawa SST Council, which is organized by 18 companies; it was inaugurated in 2014 and completed in 2018. It underlines the importance of not proposing a smart town plan based on the sole use of technology. Instead, the aim was to develop a smart community lifestyle. In particular, the overall targets for the entire town are: to achieve 70% CO2 reduction, 30% water consumption reduction as well as over 30% renewable energy usage and  lifeline maintenance of 3 days in the event of emergencies. Furthermore, after the completion, the project vision is to mature and develop eco-friendly and smart lifestyles for 100 years.

Project descriptionFujisawa SST moved from the development phase to the nurturing phase. Indeed, the Fujisawa SST Council in collaboration with diverse companies will promote Co-creation activities to develop a new smart community lifestyle. The activities currently in place are in the fields of driverless next-generation electric vehicles, events to link real spaces with virtual services, last-mile home-delivery services and overall improvements for the various detached houses.
Certification In September 2013 Fujisawa SST was adopted by the Japanese government as a model project for promoting CO2 reduction in housing and buildings, acknowledging the sustainability of the project. In addition to that, it obtained the Good Design Award 2015 (regional/community development and social contribution activities). Furthermore, the project was awarded the Year 2017 Kanagawa Global Environment Award for Global Warming Countermeasures Plan, getting the Rank S certification in CASBEE for Urban Development. Besides these awards, the Kanagawa Global Environment Award (Kanagawa Smart Energy Plan) was assigned to the project in 2015.


Before the beginning of the redevelopment project, there was an old Panasonic building in its place, which closed in 2007 and soon after demolished. Therefore, the project started in 2008 but the trend of the smart city concept of Fujisawa SST was focused only on the energy system. Then, after the Great East Japan Earthquake that occurred in 2011, the project design paradigm changed, since this date represented a turning point for Panasonic that strengthened the theme of resilience.

Sustainable Development

The main aspect that the Fujisawa SST considers is to create a smart town based on the needs of its residents. Therefore, the development of the project consists of three layers: proposal of a smart lifestyle, design of smart spaces and a creation of smart infrastructures. This process incorporates the sustainability aspect through five services – which focus on energy, security, mobility, wellness, community, and emergencies – and nine concepts – eat, stay healthy, work, learn, play, live, nurture, link and gather. Overall, to turn the concept into a real town, Fujisawa SST defines a set of numerical targets: environmental targets, energy targets, and safety and security targets. Every target, in order to be met, is composed of different guidelines: project design guidelines, town design guidelines, and community design guidelines. Based on the guidelines, the services within the town can be created and, as the last step, the activities of individuals involved in the town are considered as crucial in order to use those services.
