Over 10 Years of Fujisawa Sustainable Smart Town: Opening Up New Possibilities Towards the Future

For more than a decade, since its grand opening in 2014, Fujisawa Sustainable Smart Town (Fujisawa SST) has embodied a bold vision for life-centered, eco-conscious modern living. Presently some 2,000 people live in 566 smart town dwellings.

Designed as a model for the cities of the future, it integrates sustainability, resilience, and well-being into every aspect of daily life. By combining smart technologies, renewable energy, and community-driven initiatives, Fujisawa SST creates an efficient resident-focused environment that sets a new standard for sustainable residential development.

At the heart of Fujisawa SST is co-creation, where stakeholders actively shape the town’s evolution. From advanced mobility systems and sustainable solutions to wellness infrastructure, the town continuously refines how cutting-edge technology supports community values. This dynamic approach has made Fujisawa SST a real-world testing ground for future urban solutions, allowing it to scale innovations that enhance residents’ lives and serve as a blueprint for cities worldwide.

Since its opening, Fujisawa SST has successfully achieved its initial goals, fostering an expanding ecosystem of co-creation initiatives. The town has met its original environmental targets by reducing CO₂ emissions by 70% (compared to 1990 levels) and household water consumption by 30% (compared to the 2006 standard of household equipment), while also achieving a renewable energy utilization rate of over 30% as part of its energy goals. Additionally, as part of its safety and security objectives, it has secured lifeline infrastructure for three days in case of emergencies.

Co-creation activities such as community building and business incubation have also expanded, with over 100 demonstration experiments and marketing initiatives, including mobility solutions, and 10 successful business ventures emerging from the project.

As a result, Fujisawa SST has earned high recognition as one of Japan’s leading real-world smart towns. It has received numerous domestic and international awards, and to date, has welcomed more than 41,000 visitors from 60 countries on study tours.

“From the very beginning, our approach wasn’t just about closing down a former factory site—it was about creating a new town and finding a fresh way to contribute to the local community,” explains Fujisawa SST Project Leader, Harumi Tanaka, Manager of Smart City Group, Business Solutions Division, Panasonic Operational Excellence Co., Ltd. “By incorporating environmental initiatives and cutting-edge technology demonstrations, we’ve attracted visitors not only from across Japan but from around the world. It’s exciting to see our vision for a sustainable and innovative town being recognized and appreciated.”

As Fujisawa SST enters its next phase of development, environmental sustainability remains a top priority. By 2034, the town aims to reduce CO₂ emissions by 50% compared to 2020 levels, with over 60% of its renewable energy self-consumption rate striving towards the goal of producing and consuming energy at home. To achieve this, the town is continuously evolving its energy infrastructure, enhancing solar power networks, and adopting next-generation energy storage technologies and energy saving solutions.

One promising initiative in this transition is the deployment of Glass-based Perovskite Photovoltaic, which tested in a model home up to March of 2025. This next-generation photovoltaic offers not only high efficiency, but also flexibility in size, transmittance, and design, allowing for customization according to specific requirements, enabling power generation in places where conventional solar cells cannot be installed and making them ideal for urban environments. This so-called “energy-generating glass” aims to harmonize urban aesthetics with renewable energy generation, contributing to CO₂ reduction and power resilience. By advancing such original technologies, Panasonic seeks to expand practical applications and drive the future of sustainable cityscapes.

Another pillar of the town’s sustainability vision is the Circular Town Project, which focuses on optimizing resource use and minimizing waste. Its goal is to analyze material flows within the community and identify ways to improve recycling efficiency and reduce raw materials consumption. For example, excess renewable energy generated by homes can be shared with town facilities, ensuring a balanced and consistent supply. Additionally, local businesses and residents can actively participate in reuse initiatives, fostering a circular economy that prioritizes sustainability.

Meanwhile, all single-family homes are equipped with a Home Energy Management System (HEMS), ensuring power and hot water supply through solar power and ENE-FARM (energy farming) systems in emergencies. Energy usage data collected via integrated HEMS in detached homes will not only help visualize the town’s environmental goals but also allow analysis of data tied to household demographics. This data-driven approach enables Fujisawa SST to evolve dynamically, ensuring a smarter, more resilient urban environment tailored to the needs of its residents.

Fujisawa SST was designed with resilience at its core, integrating advanced infrastructure and smart technologies to ensure stability in emergencies. The town’s disaster-resistant features include underground power and communication lines, earthquake-resistant gas pipelines, and decentralized energy systems that maintain reliable operations even during crises. Buildings incorporate passive design elements that enhance structural integrity while optimizing energy efficiency.

To further strengthen preparedness, Fujisawa SST looks ahead to leveraging digital twin simulations to enhance disaster response strategies. Such real-time virtual models can allow authorities to simulate emergency scenarios, optimize evacuation plans, and improve coordination. Additionally, interactive drills and training sessions will ensure the community stays well-prepared and ready to respond effectively in times of crisis.

Energy security is a key pillar of the town’s resilience strategy. The expansion of emergency energy storage solutions, including community power banks that store excess solar energy, will ensure a stable power supply during outages. AI-equipped drones will also be deployed for continuous risk management, monitoring environmental conditions, and optimizing crisis management efforts.

In the event of a disaster, Fujisawa SST is designed to remain self-sufficient. The town will sustain three days of uninterrupted essential services and maintain a seven-day stockpile of food and water, ensuring the well-being of its residents. By prioritizing self-sufficiency and proactive crisis management, Fujisawa SST sets a new standard for disaster-resilient smart cities.

Fujisawa SST is dedicated to enhancing residents’ well-being by integrating smart solutions that promote health, community engagement, and sustainable mobility under the theme, “fostering life skills from ages 0 to 100 and beyond.” The Park Wellstate Shonan senior residence features AI-assisted healthcare monitoring to assist a resident’s daily routines while ensuring safety and independence. Complementing this, the Wellness Square serves as a multi-functional hub, combining serviced housing for seniors with pharmacy, nursery, and cram school, creating an intergenerational space that fosters health, welfare, and lifelong learning.

Active lifestyles and recreation also play a vital role in Fujisawa SST’s vision. The Mizuno Sports Plaza offers interactive wellness programs and community sports initiatives, encouraging residents of all ages to stay active while building social connections.

Beyond physical health, social and cultural engagement are central to the town’s identity. Fujisawa SST hosts regular workshops, arts and culture festivals, and technology showcases, bringing together residents and external collaborators. Programs like the Fujisawa Town Parent Project empower locals to organize events that welcome neighboring communities and deepen their connection to the town.  

The town is also reshaping urban mobility to make daily life more convenient and sustainable. Electric vehicle-sharing services, AI-powered route optimization, and pedestrian-friendly urban design are reducing congestion and improving accessibility, while also participating in Japan’s first demonstration experiment of simultaneous operation of 10 remotely operated small vehicles in multiple areas as an operation center and driving implementation site. Looking ahead, Fujisawa SST plans to pilot low-speed electric transport for short distances and drone-assisted delivery services, further enhancing urban mobility.     

By integrating smart health services, active lifestyle programs, cultural initiatives, and sustainable transportation, Fujisawa SST continues to set new standards for community well-being in the cities of tomorrow.

As Fujisawa SST celebrates its 10th anniversary, it stands as a global model for sustainable city planning. Over the past decade, the town has demonstrated how smart technologies, community-driven initiatives, and resilient infrastructure can create a thriving, future-ready urban environment.

With ambitious targets for carbon neutrality, disaster preparedness, and enhanced well-being, Fujisawa SST continues to push the boundaries of what a smart city can achieve.

Looking ahead, the next phase of Fujisawa SST’s evolution will focus on scaling its innovative urban solutions beyond its current boundaries.
