DYNAMIC CHANGE OF HOUSEHOLD AND RESIDENTIAL ENVIRONMENT ISSUES IN STATION CENTERED COMMERCIAL AREAS OF TOKYO METROPOLITAN SUBURBS

首都圏郊外の駅前商業地区における世帯動向の実態と居住環境の課題に関する研究

In the Tokyo Metropolitan suburbs, the clustering of retailers has resulted in highly densified commercial clusters around railway stations. These areas play important roles as the commercial center for the suburbs. However, recent observations indicate a trend of rising housing development spurred by increased demand for residential real estate within the proximity of the station. This paper clarifies the environmental issues faced by these commercial areas that have resulted from the increment in housing development. The analysis on the dynamic change of the number of households and housing development is conducted through field survey and statistical study on 87 sites. According to the National Census, the average number of households in station centered commercial area has increased. Although this increase is generally considered important for commercial revitalization, the number of retailers in these commercial areas has been witnessed to decline between 2005 and 2015 in 73.9% of the target sites. Apart from the observed “residentializing” trend, this phenomenon is further accompanied by changes in housing types. The proportion of household living in privately-owned houses and medium-to-high-rise housing is on the rise in all sites. Along with the increase in the number of households, the number of single dwellers and families composed of only elderly has been increasing significantly. The fluctuations in the ratio of production-age households and households including children has different effects depending on the site characteristics. Public facility developments for residents have not necessarily responded to the trend of household changes. Through the spatial data analysis of facility development between 2009 and 2016, it has been clarified that the ratio of welfare and medical facilities per household has been declined. The one fourth of target areas public parks has also been developed, but they are not sufficient to meet the growth of residential demand. Uncontrolled housing development without public facility development is an identified problem to be considered. This research also focuses on case studies of commercial areas around the Kashiwa station and the Motoyawata station to provide details on the “residentializing” process at the district scale. Housing development has increased remarkably by more than 25% over the last 10 years in these commercial areas. The comparison of the two sites indicates that there are three common housing development types in both areas: (1) Skyscraper condominium developments close to a station by urban redevelopment project, (2) medium-to-high-rise housing development in each retail site and (3) low-rise housing development situated at areas with poor road accessibility. Half of these developments are developed as strictly residential use housing and therefore do not contribute to the commercial activity of the area. There are also concerns about the negative influence for public facilities standards. In Japan, it is expected that compact city policy will lead to more and more housing developments in station centered commercial areas. In order to improve the residential environment in the future and encourage residents activity and diversity of activities in station centered commercial area, these areas should be redeveloped as mix-use areas, thus allowing public, commercial and residential to be more present.
