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.

This paper aims to clarify physical characteristic of empty house and vacant floor in historic district on Cheongju. First, most empty houses are the timbered houses of 1 story, and it will be built before the 1969. And the building of a vacant floor has a common non-residential buildings of 4 stories, and there are many buildings of RC structure built in the 1980s. Second, when the situation of an empty house and a vacant floor was seen, there was most the second floor only by the number of room, but when seen from the ratio of the whole number of rooms, there were most the third floor and the fourth floor. Third, when the situation of a vacant floor and a vacant room was seen from use, there were most store, shop and office. Relevance with this as close as reduction of the population in the center of Cheongju is seen. Moreover, the grope of a method which can utilize this is required.

This paper is to survey the cooperation between the school and the community with respect to the degree of share of their facilities. The hypothesis of this paper is that the share of facilities between the school and the community is helpful for the two. That is, the community, using the school facilities, can educate to upgrade its people to higher social level. The school, using the community facilities, can compensate insufficient school facilities and facilitate student learnings. This paper employed both a literature survey and a case study approach explained by the case of Seong Dong Gu and its schools. This paper argued that the share of the facilities between the school and the community is needed to facilitate student learnings and to upgrade community people to higher level. Thus, government should encourage the cooperation between the two. This paper found that the school can use other schools' facilities, camping facilities, various types of private institute, community libraries, social welfare centers, athlentic facilities, and park facilities in the community. Most of the facilities are rested during school hours and are vacant more or less after school hours, so that there are still room for share the facilities with the students. This paper found that the community can easily use school facilities for life-long education programs, house-wife classes, athlentic programs for daily life, recreation classes for community people because the school is located in the center of the community. These programs using school facilities can encourage to upgrade community persons' social levels. However, this paper found that the degree of community use is insufficient to fulfil the school facilities. Only a few percent of the school class rooms and other facilities are used by the community. Therefore this paper asserted that community education programs using school facilities should be expanded. This paper recommended, based on the findings, that governments should encourage the cooperation between the school and the community to facilitate student's learnings and to upgrade community people to higher level. Also it recommended that the school should share more community facilities and that the community should share more school facilities.
