Objectives: To conduct market area analysis from a micro-marketing approach with GIS by using customer data stored on IC Cards. The customer data is integrated in to digital maps by address matching process and user density calculations by voronoi polygons as well as customer distribution pattern analysis by network distance is being conducted. Regional population distribution data is essential to this type of analysis on market area and customer distribution, but the data in my laboratory was limited to small units and was not enough to conduct a detailed and elaborate analysis. The data necessary was provided from The Center for Spatial Information Science.

Objectives: Membership facilities such as an athletic sports club, differ from the general commercial facility in means that it requires a stable increase in use efficiency at any hour or day. In general, retail and service businesses set their goals to increase the total number of customers, whereas membership facilities, customer congestion occurring in a certain hour of the day is considered a minus factor. Membership facilities desire an average number of customers coming in evenly in each hour of the day to avoid facility vacancy. Because facility-user data is very hard to obtain, research based on user behavior was almost unheard of. So for this research, we focused on the time aspect and studied facility user attribute and user behavior. With the cooperation of an athletic sports company, we obtained user data on doorway activity of a specific facility in Denencho-fu, Tokyo. On analyzing the relation between this and user distribution, we used attribute data of the National Census data on small units of the local area (Setagaya-ward in Tokyo city, Mitaka city, Chofu city, Komae city, Fuchu city). Research will focus on the relation between facility users and local population density, member per household, occupation characteristics.

Objectives: In a city, there are many buildings using toponyms (geographic names) on their names. Toponyms should be used where they are actually located, but this does not always apply. For example, an apartment located in Kinuta district bears the toponym "Seijo". It seems that using the toponym of well known area regarded as a brand sends a better image. Which leads to the hypothesis, a toponym with a brand image is used more often; therefore exceeding it's actual geographical location. Under this theory, this research aims to clarify the scale of each district's brand image.
