The recent increase in the number of vacant houses in Japan has become a serious problem. To address this problem, the distribution and main factors affecting the occurrence of vacant houses should be analyzed. Thus, this study was designed to quantitatively examine the number and distribution of vacant houses in the small provincial town of Fuchu City, Japan. The factors contributing to the occurrence and quantity of vacant houses were analyzed from the perspectives of societal, environmental, and property characteristics using discriminant analysis and multiple regression analysis. The results indicated that some factors influencing the occurrence and quantity of vacant houses are identical while others are different. The population size and proportion of small lots have an impact on both the occurrence and quantity of vacant houses. In addition, the distance to a department store, the proportion of elderly population, and the presence of low-rise buildings affect the occurrence of vacant houses. Moreover, natural land, such as forests and rice fields, and proportion of buildings with garages are factors affecting the quantity of vacant houses.

最近日本空置房屋数量的增加已经成为一个严重的问题。针对这一问题，应分析空置房的分布及影响其发生的主要因素。因此，本研究旨在定量研究日本府中市省级小镇的空置房屋数量和分布。利用判别分析和多元回归分析，从社会、环境和财产特征的角度分析了影响空置房屋发生和数量的因素。结果表明，影响空置房屋发生和数量的因素有些相同，有些则不同。人口规模和小地块的比例对空置房屋的发生和数量都有影响。此外，与百货公司的距离、老年人口的比例以及低层建筑的存在都会影响空置房屋的发生。此外，森林、稻田等自然用地、带车库的建筑比例也是影响空置房数量的因素。
