In order to address planning themes such as smart grid and midtown revitalization we need to have a framework to view a city. We stress the importance to analyze our city from the unified viewpoint of consumer behaviors. To do this enables us not only to disentangle how various aspects of our city are related with each other but to construct a scientific method to assess how various policies enhance the value of our city. We call this the town equity research. Moreover, with recent advanced mobile technologies like smart phones and location services utilized to obtain micro-data of human behaviors, the town equity research for strategic town management will open an ample research frontier for real estate sciences as big data sciences.

A low carbon type city and a community development of our country will enter a new era after The Great East Japan Earthquake on March 11, 2011. This is because energy policy selection pressurizes us to select the fadeout the nuclear power reactor here in Japan. When a nuclear power reactor fadeout is chosen in near future, we have to be dependent on thermal power generation until the arrival of the new age that will be greatly supported by natural-energy power-sources. Usually, the thermal power generation discharges CO2 so much, greater or lesser depending on the kinds of thermal energy sources. When low-carbon type city and a community development will be planned from now on, it is necessary to achieve not only CO２ reduction but reduction of an environmental impact in all scenes. In this paper, while illustrating the policy issue corresponding to the degree of matureness of the city and the community development projects, I would like to introduce a case of the low carbonation and eco-friendly urban redevelopment project actually planned and carried out in the center of Tokyo.

The purpose of this study is to verify the impact of the earthquake risk on the value of office buildings. To examine the effects of vulnerability to building and probable maximum loss on price, rent, and appraisal cap rates, the use of which is office, these dependent variables are regressed on characteristics of the property by cross-sectional hedonic model. As a result, it was found that the vulnerability to building collapse decrease unit prices of office buildings by 7.5% and rents of those by 7.6%. On the other hand, the vulnerability to building collapse didn’t impact on cap rates of office buildings.
