Hitachi Review Vol. 61 (2012), No. 3 108 Special Contribution Taking Japan’s Smart City Model to the World Hiromichi Iwasa —Kashiwanoha Campus City— Chairman and Chief Executive Officer Mitsui Fudosan Co., Ltd. Town Planning’s Role in Solving it is being put into practice is in the smart city model at Problems of Both Japan and the World Kashiwanoha Campus City described in this article (see Fig. 1 The recent Great East Japan Earthquake has left a sense of and Fig. 2). The challenges posed by the environment, energy, sorrow at the extensive loss of precious lives and of the need and aging populations are shared by all nations, particularly to be prepared for major disasters lodged deeply in people’s advanced economies, and what is needed most of all at this hearts. It has also forcibly reminded us of the finite nature point in time is a solution model. Ahead of the rest of the of electric power and that modern civilization is built on world in its need to deal with these issues, Japan’s problem extremely fragile foundations. Environmental and resource solving capabilities are attracting attention from around the problems and threats to biodiversity represent the negative world, and it is fair to say that people are looking forward to face of economic progress, and while these continue to seeing these solutions achieved. intensify on a global scale, rapidly aging populations in advanced economies, particularly Japan, are leading Town Planning for Kashiwanoha toward social impoverishment and decline. I believe this Campus City dangerous situation we now face can be rephrased in terms A new lifestyle center is starting to take shape at of the following question: given these conditions of limited Kashiwa City in Chiba Prefecture, a town of 400,000 people resources and energy, declining populations, aging societies, located 30 minutes by the Tsukuba Express from Akihabara and mature markets and industries, can we recreate the sort in Tokyo. Centered around the Kashiwanoha Campus of vital and growing societies we once had? Station on the Tsukuba Express line, Kashiwanoha Campus Naturally, my answer is yes. The key, I believe, lies in City is a model next-generation city that incorporates the town planning. Whereas “growth” was the core value of latest technologies, services, and systems combined with a society back in the era of rapid expansion, our core value participatory social experience for residents. It is being built now is “sustainability.” That is, the answer lies in the ability through a joint public-private-academic project involving to pass our society on from generation to generation. As Kashiwa City, Chiba Prefecture, The University of Tokyo, the problems we face are complex in structure, being and Chiba University. The aim is to construct a smart city for multifaceted and interlinked, we need to take a broad view extended healthy living and the creation of new industry. of the individual challenges and seek out ways of solving Kashiwanoha Campus City brings together the latest these simultaneously in an organic way. This is what the knowledge from The University of Tokyo, Chiba University, town planning approach is all about and one place where and elsewhere to produce a problem solving model and is Kashiwa Campus of The University of Tokyo Kashiwanoha Park Kashiwanoha Campus of Chiba University District 147 District 148 LaLaport Kashiwanoha UDCK Park City Kashiwanoha Campus Ichibangai (1st Street) UDCK: Urban Design Center Kashiwa-no-ha Fig.UDCK: 1 — Urban Overview Design of Center Kashiwanoha Kashiwa-no-ha Campus City and Surrounds.

The aim is to build a new social system called the “Co- energy sources, it will become a common practice for them to Create Eco-System” (a joint approach to sustainability), which switch roles flexibly as circumstances require while producing, allows everyone who feels a desire to contribute to their region, storing, and conserving energy on a regional basis.

Such participatory low-carbon communities The Great East Japan Earthquake has led to a major will lead to the creation of a new lifestyle in which electricity reappraisal of town planning values. It has shown up the fragility conservation becomes part of daily life (see Fig. 3). of society relying on large power systems such as nuclear power plants and has brought a lifestyle shift from one in which Taking Growth-oriented, Fine-tuned a reliable supply of electric power was taken for granted to one Japanese Smart City Model to the World in which the problem of energy is recognized as a fact of life. In addition to building low-carbon cities around the What is needed for the future is an optimum mix of centralized grid-based energy sources such as thermal or nuclear power Diverse lifestyle proposals Multimodal transportation sharing schemes and distributed power supplies that combine elements such Kashihana Project On-demand bus EV car sharing as community-based photovoltaic, wind, biomass, and other forms of renewable energy as well as cogeneration and storage batteries. The objective is to perform overall optimization of power, gas, heat, unused energy, and other sources to achieve Integrated transport efficient energy management. It is also recognized that we information database need to construct robust energy networks that can withstand Marche Couleur disasters, including providing alternate lines of energy supply in order to ensure security of supply. Electric bike sharing Shared push bikes In the past, suppliers and consumers have been separated, with users able to consume without regard for EV: electric vehicle the overall energy supply. The first thing we need to do is to change this approach. As consumers and suppliers will Fig. 4 — Fantastic Outlook for Future Communities.
