초록

The suburban residential areas encircling major Japanese cities, established during the era of rapid economic growth, grapple with a formidable challenge as their original residents age swiftly. The migration of individuals toward city centers and proximity to train stations, coupled with an aging populace and diminishing birthrate, portends a diminishing functionality of these towns, significantly impacting residents' lives and posing a potential threat to their future. Within the context of a rapidly aging society, the effective utilization of the substantial existing housing stock emerges as a critical issue, essential for shaping future housing policies in a super-aging society. This thesis investigates vacant rooms within detached houses, a segment of spatial stock, with the goal of comprehending the mechanisms instigating their occurrence. The aim is to predict their future through the formulation of a mathematical equation encapsulating the conditions leading to their formation. Through the analysis of data from 76 houses out of 118 questionnaires and 36 interviews, where respondents acknowledged having vacant rooms, the study seeks to elucidate the governing mechanisms. It identifies factors exhibiting correlation or causal relationships with the emergence of vacant rooms by scrutinizing the timing and circumstances of the current vacant rooms. The thesis asserts that the genesis of vacant spaces can be explicated by a simple equation, notably linked with life plans. It introduces three scenarios-optimistic, intermediate, and pessimistic-and provides recommendations for addressing potential outcomes. In the backdrop of a diminishing and aging population, understanding available spatial resources is pivotal. The thesis contends that the detailed exploration of each scenario offers crucial insights for cultivating sustainable residential communities, extending beyond urban planning to encompass area management, individual decision-making, and the development of commercially viable housing aligned with these decisions.
