The most densely populated area in the twenty-three wards of Tokyo is identified as a zone of five to ten kilometers which is centered at Shimbashi station by using Small Area Statistics of 2010 Population Census of Japan. This paper analyses the characteristics of population, households, and dwelling houses in 5 to 10 kilometer zone, comparing with inner and outer zones. It becomes clear that the high densely populated circular area of 5 to 10 kilometer zone is formed by one-person households of 20 age and 30 age groups residing in small apartments of floor space less than 49 square meters and the medium- and high-levels layer.

<p>Due to the increase in a necessity, operability, and data availability, spatio-temporal analysis has been gathering popularity. However, there are few studies focusing on systematic reviews of it. This paper first shows basic concepts for spatio-temporal analysis such as geometrical representation of entities and changeability of attribute values over time. Then the paper constructs a matrix showing the characteristics of earlier studies. The matrix consists of two stages, where the first stage concerns the temporal representation and types of the entities, and the second stage concerns spatial representation, changeability of location, shapes and attribute values. The matrix helps us to understand the characteristics of the studies and uniqueness or similarity when compared to others.</p>

The present study seeks to provide meanings to distortions in historical maps from Edo Period by using Euclidean regression analysis, which is already theoretically systematized in cognitive map studies of geography. As for meanings or factors of distortions, cognitive and other possibilities are presented. In addition, the present study attempts to construct correction models of historical maps based on characteristics of distortions found in the above-mentioned process of providing meanings to distortions.

This study aims to investigate the association between individual travel behaviors, neighborhood built environment, and social area type based on a geodemographics dataset. Neighborhood environment includes population density, land use mixture, road density, service level of public transportation, destination accessibility, and topography. By using person trip survey data for Kyoto Prefecture residents in 2010, the results of multilevel logistic analysis showed that social area type can explain the variations of travel mode choice for commuting behavior―particularly the use of public transportation and vehicle, even after controlling for neighborhood environment and individual characteristics such as gender, age, occupation, and household vehicle ownership. On the other hand, there was little evidence of association between mode choice for shopping and social area type.

This paper reports the development of a time-series topographic map viewer "Konjyaku Map 2": Capital, Chukyo and Keihanshin Area Edition, working on Windows 2000/XP/VISTA . Although there are considerable needs for acquiring knowledge of the past status of local areas, it takes a lot of time and effort to satisfy such needs. The software shows old topographic maps on a scale of 1 to 25,000 since the early 1900s and is downloadable from the internet. The software was developed for viewing maps with these fairly simple functions and can thus be easily operated.

Demographic composition, e.g., population composition by age-groups, is one of the most basic information for discussing regional issue or planning. The present study compares the future Japan through 2010-2060, estimated by National Institute of Population and Social Security Research, with all municipalities in 2010 from the perspective of demographic compositions classified by fiveyear age groups (0-4, 5-9, ..., 90+). The (dis-)similarity of compositional data can be measured with Aitchison distance, one of the core concepts of compositional data analysis. We create choropleth maps based on Aitchison distance. The maps, for example, indicate that the demographic composition of Sobetsu-cho of Hokkaido prefecture of 2010 is the most analogous of the future of Japan of 2060.

Since 2007, East Japan Railway Company has been selling sets of an IC transit card called “Suica” and discounted tickets for an airport shuttle N'EX (Narita Express) to foreign tourists coming to Japan. In this paper, we use the transit data of Suica & N'EX to investigate the behavior of inbound tourists in the Tokyo Metropolitan Area. From our sequence alignment analysis, the movement of inbound tourists has been identified as two patterns: (1) spending longtime in one area, and (2) being around multiple areas. In addition, a list of stations where tourists frequently mistakenly enter has been extracted. Furthermore, we compared the actual length of time between stations with the expected travel time when using the shortest path and identified several routes where tourists tended to take unnecessary detours.

<p>The aim of this paper is to examine regional differences in the prevalence of pollinosis by social area type in a geodemographics dataset by carrying out binomial logistic regression analysis on the 2002-2006 Japanese General Social Surveys (JGSS) data. The results indicate that people living in rural areas and working in the agriculture and forestry industries are less prone to contracting pollinosis, and people with a higher household income have a higher risk of contracting the disease compared to those with a lower household income. These findings are consistent with the hygiene hypothesis that sanitary environments impair normal development of immunity and increase the risk of contracting allergic diseases. This study also exemplifies the usefulness of geodemographics as a concise indicator of the local environment for explanatory analysis of environmental health risks of pollinosis.</p>

Making thematic maps with drawing software packages on personal computers will bring a significant contribution to the education of geography and to the analysis of micro-scale landuse maps there by making them more available and simplifying their operation. This study demon-strates the method of plotting a landuse map with a drawing software package and analyzes the completed map with an image processing program. The plotting methods are focused on (1) draw-ings of parallel lines, (2) partition of land plots, (3) selection of fonts, and (4) modification and selec-tion of patterns for land plots. The analysis also confirms, the measurement of land plots and the procedures for improving their precision. These techniques for plotting and analyzing a landuse map provide a basis for making all other thematic maps to be printed out in gray scale.

We developed a flooding-type algorithm for drainage network extraction and show a full program source in the language C. The program generates automatically Drainage Direction Matrices (DDMs) from Digital Elevation Models (DEMs) with sink holes. By using a random technique of random walk type, the drainage networks are processed adequately in flat plains or alluvial fans.
