Tokyo, Japan - Panasonic Corporation and eight other companies that are spearheading advanced environmental initiatives through eco-conscious urban development and smart city projects today announced they will work together to implement a smart town concept called “Fujisawa Sustainable Smart Town (Fujisawa SST)” which showcases Panasonic’s “entire solutions” business model in full scale to the world. The city of Fujisawa, in cooperation with the surrounding regions, will also participate in the efforts to globally promote Fujisawa SST as a model project of an environmentally-minded city in action.

The eight leading companies are Accenture, Mitsui & Co., Ltd., Mitsui Fudosan Co., Ltd., Nihon Sekkei, Inc., ORIX Corporation, PanaHome Corporation, Sumitomo Trust & Banking Co., Ltd. and Tokyo Gas., Ltd. in alphabetical order.

Panasonic and Fujisawa City in Kanagawa Prefecture, situated about 50 km west of Tokyo, reached a basic agreement last year to build a smart town on the vacant lot of Panasonic’s former factory site as they announced on November 17, 2010. With an aim to open the new town in the fiscal year ending in March 2014, the business partnership of these nine companies and one city will collaborate to build an innovative smart town deploying services and energy systems based on Panasonic’s Eco Ideas for green lifestyles. The developers, manufacturers and service providers will work closely together throughout every phase of the project, from the master planning stage to actual operation of the town that will have about 1,000 households.

Panasonic will apply its “comprehensive solutions for the entire house, entire building and entire town” to Fujisawa SST, combining its energy technologies and a safe and secure environment. The company will effectively create an advanced model of a town demonstrating efficient use of energy by promoting widespread use of energy-saving devices and proposing new solutions that integrate measures for energy creation, storage and management. Specifically, the company plans to preinstall its solar power generation systems and home-use storage battery systems across the town, including homes, various facilities and public zones, which would be the first of its kind in the world. Panasonic intends to replicate Fujisawa SST as a business model in other parts of Japan and overseas.

- Fujisawa Sustainable Smart Town Project -

Vision and Background

Global demand for the development of new cities, mainly driven by Asia, is expected to reach 3,100 trillion yen by 2030, prompting numerous projects in cities throughout the world for the development of smart cities and eco cities aimed at achieving low carbon societies.

Currently, many projects are being launched as pilot projects or technical demonstrations to verify their feasibility. However, in order to promote the full-scale deployment of smart cities and eco cities on a global scale, it is important to provide consumers with solutions for achieving a new lifestyle as well as enhancing home’s value and economic merits through the development of ecology-minded towns.

Furthermore, after the Great East Japan Earthquake, there is renewed attention for energy infrastructures that are safe and secure with solar power generation systems and storage battery systems installed on a community basis.

Against such a backdrop, this project aims to realize Panasonic’ concept of a safe, secure and sustainable smart town that embraces nature to the fullest extent as well as produces energy for local use in the town. At the same time, the project looks to create a smart town that is connected to the power and data networks right from the start, allowing for optimal control without burdening the residents. Through these initiatives, the town as a whole aims to reduce carbon dioxide emissions by 70 percent, compared to the 1990 levels.

Panasonic will bring together its know-how built up through participation in eco and smart city projects in Japan and overseas to implement its “entire solutions for the town” in the Fujisawa SST project, and contribute to the realization of low carbon lifestyles throughout the world by promoting this business model.


  1. Master planning for providing eco-conscious, comfortable lifestyle and services after the development and sales
    The Fujisawa SST project will adopt city block designs that take into consideration “how to achieve a natural environment that is in harmony with the people’s lifestyles” and “how to provide more efficient services in the area” in order to improve the town’s value over time even after the development and sales of residential homes and lots.

    Items Under Consideration
    • Organic city block plans that incorporate nature and energy systems, and designs that match the landscape.
      - Create a “green axis” by establishing parks and planting vegetation along the main roads and form “wind paths” that take into consideration the wind direction in Fujisawa.
      - Achieve a solar panel design that blends with the town’s lush green landscape.
      - Develop basic specifications for homes with ample space for installing storage battery equipment and other energy systems.
