ABSTRACT

In detached housing estates in the suburbs of Tokyo, increasing vacancies in inherited houses have become a problem. This study aimed to assess the risk of vacant house generation and identify risk factors through analyses focusing on parent–child discussions. A questionnaire survey of parents in Koma-Musashidai, Saitama Prefecture, and their children who lived apart regarding their future intentions of inheritance of the parents’ houses using cross and logistic regression analyses revealed that 66.5% of the parent–child pairs had had no discussion, 20.5% had different impressions of the results of the discussion, and 7.8% were at high risk of producing vacant houses. Furthermore, the analyses identified the factors associated with parents’ intention to bequeath their houses: discussions with their children, old age, high age of the house, lack of proactive measures, anxiety about renting, and stronger community attachment; and the factors associated with children’s intention to leave their parents’ houses: inadequate discussions with their parents, home ownership, and lack of relationships with neighbors. These results suggest that it could be beneficial to encourage parents and children to participate together in seminars and consult with experts before parents become older to reduce the risk of vacant houses.

摘要

在东京郊区的独立住宅区，继承房屋的空置率增加已成为一个问题。本研究旨在评估空置房屋产生的风险，并通过侧重于亲子讨论的分析来确定风险因素。对埼玉县狛武藏台的父母及其分居子女进行交叉回归和logistic回归分析的问卷调查显示，66.5%的亲子对没有讨论，20.5%的人对讨论结果有不同的印象，7.8%的人处于生产空置房屋的高风险之中。此外，分析确定了与父母遗赠房屋意向相关的因素：与孩子的讨论、年老、房屋的高龄、缺乏积极主动的措施，租房焦虑，社区依附性更强；以及与孩子打算离开父母家相关的因素：与父母的讨论不足、房屋所有权以及与邻居缺乏关系。这些结果表明，鼓励父母和孩子一起参加研讨会并在父母变老之前咨询专家以降低空置房屋的风险可能是有益的。
