The number of vacant dwellings in Japan is on the rise, reaching 8.5 million nationwide in 2018, or 13.6% in terms of the vacant house rate. The purpose of this study is to clarify the relationship between the occurrence of vacant dwellings and regional characteristics by capturing the number of vacant dwellings in chronological order and analyzing the relationship with the regional characteristics that affect it. The analytical method used in this study is multiple regression analysis, with the objective variable being the number of vacant dwellings and the explanatory variable being regional characteristics. Using the analysis results, the correlation between the number of vacant dwellings and the regional characteristics is comparatively analyzed at multiple points in time. The results show that around 2008, the regions with larger numbers of "households," "single-person households," and "elderly people. tended to have more vacant dwellings. Around 2013, the regions where the “accommodation industry” was thriving had more vacant dwellings, but the regions with high convenience to major stations (Yokohama Station/Tokyo Station) and well-established living infrastructure had less vacant dwellings. In 2018, the relationship with locational factors was weakened and the relationship with economic and facility factors was strengthened though the trend continued.
