The purpose of this study is to examine the policy direction and execution plans of the Japanese central and local governments for the use of vacant houses after the enactment of the "Special Act on Vacant Houses." It also seeks to provide suggestions for establishing vacant house policies in Korea by identifying the characteristics of the Japanese policies, and to suggest policy alternatives that can contribute to environmental improvement and regional revitalization through the use of vacant houses. For this purpose, we examined Japan's "Special Act on Vacant Houses," the process of establishing vacant house policies in the Japanese central and local governments, and the contents and direction of these policies. Below are the results of this study. First, the Japanese government revised mid to long-term policies related to housing after the enactment of the "Special Act on Vacant Houses", thereby providing ground for local governments to establish vacant house policies. Second, the government actively supported the operation and funding of related associations so that the private sector rather than the public sector could address vacant house problems. Third, the government subsidized administrative expenses such as cost of finding vacant house owners to prevent neglect of vacant houses, and showed its will to address vacant house problems by revising taxes such as property taxes and transfer income taxes. Fourth, the government has enacted distinct ordinances for each local government and made it possible to perform customized policies such as allowing residents and local stakeholders to participate in the establishment of vacant house policies. Fifth, the government made it possible to manage vacant houses efficiently by allowing the vacant house bank to provide all information related to the use of vacant houses. It is necessary for Korea's central and local governments to refer to these precedent cases and create efforts to reduce trial and error when establishing vacant house policies.

Recently people are starting to pay attention to the vacant house. Vacant house across the country are expected to be a Million. Ministry of Land, Transport and Maritime Affairs has created a new legal provisions regarding maintenance to Vacant on the Construction Law. But Vacant house information systems in government are not available Other countries to clarify the role each entity to manage these Vacant and manages the Vacant. The national government has made the operating budget support program for the Vacant management. The local government has made legislation of self-government to create a DB for the Vacant management. A non-profit corporation is developing a program operated by the Vacant, and the Vacant intermediaries to consumers. Therefore, our country is also to expand the national budget for the Vacant administration, local governments should establish a comprehensive management system for managing and providing Vacant house research and DB.

Vacant houses are increasing across the country, but the appropriate measures have not been set up yet. Accordingly, vacant houses are left unattended for a long time, and become deserted to degrade the residential environment. They are often used as the space for the deviation of youth or even for crimes, threatening the safety of rural society. Vacant houses are not only personal properties but also public assets that form the residential environment of a town. Therefore, the problem should be better taken care of with appropriate policies. In this study, the present situation of vacant houses in Korea, the causes of the vacant house and the limits and lessons of the improvement projects were reviewed, along with the vacant house improvement systems in the UK and Japan. The most significant difference between the cases in Korea and other countries are the method of vacant house improvement. In terms of policies and support, Korea focuses on demolition, whereas other countries focus on reuse. In addition, the vacant house improvement projects in Korea are performed mostly by government agencies, whereas local governments and private organizations in other countries cooperate to improve vacant houses and go beyond mere residential environment improvement towards the local revitalization. Based on the study results, the following are proposed to efficiently improve and use the rural vacant houses. First, the Rearrangement of Agricultural and Fishing Villages Act, which allows the vacant houses to be left unattended and not improved, should be revised. Second, the intermediate support organizations that connect the demand and supply should be fostered and supported so that the use of vacant houses can be vitalized and privately led. Third, the best practices of using the vacant houses should be found and promoted, and the vacant house remodeling technique should be developed and propagated. Fourth, a special law should be enacted to comprehensively plan, support and execute the vacant house improvement, as in Japan. Finally, the value of the vacant houses as public properties should be shared in public so that all citizens can participate in addressing the vacant house issue to derive the detailed plans to solve the problem.

This study has analyzed overseas projects of building rural communities using vacant houses. It is aimed at identifying the roles of NPO in the community-building projects and providing implications applicable to Korea. In recent years, there has been a spike in the number of vacant houses in rural areas. It is due to rapid urbanization and uneven distribution of the population across the country. Those are the reasons that prompted community-building projects. To solve the vacant house issue, there has been rising interest in building communities through vacant houses as rural resources and effectively integrating them as useful resources. However, the roles of key entity that pursues community-building projects using vacant houses have not been discussed sufficiently. Thus, this study deals with the 'Vacant House Recreation Project of NPO Corporation in Onomichi' in Hiroshima, Japan. Through the case study, the following are introduced as NPO's roles in community-building projects using vacant houses. First, pursuing promotion and attracting attention by making the utilization of vacant houses sensational; system improvement; offering information. Second, enhancing the perception of local residents by offering local services using vacant houses; offering community-building items. Third, forming a place of public discussion to solve conflicts during community-building projects using vacant houses; offering alternatives to building communities. Above all, such roles have led to the key status of NPO during its community-building projects using vacant houses. It offers the following implication for Korea: Future vacant house-related policies for rural revitalization should be done from community-building standpoint and include establishing the roles of NPO.

In rural areas, changes in the agricultural structure began to appear as the vulnerable class increased due to a decrease in population such as a decrease in fertility and aging, and the elderly were unable to engage in agriculture. The number of farmers and farmers is steadily decreasing, and the elderly population living in rural areas is steadily increasing. Rural houses are left empty due to the moving, hospitalization, and death of the elderly population. The purpose of this study aims to present the current status of vacant houses in rural areas, problems of vacant houses policy in rural areas, and improvement plans. The purpose of this study aims to analyze the population status and aging of rural areas, and to present a plan to improve the trend of vacant houses with cities and the problems of vacant house policies. This study was conducted in the following process. First, the definition of vacant houses in rural areas should be redefined. Second, it is necessary to analyze the causes of vacant houses in rural areas and plan the use of vacant houses linked to them.Third, the management system of vacant houses in rural areas should be clear.

The extinction crisis of local cities, caused by a population density increase phenomenon in capital regions, directly causes the increase of vacant houses in local cities. According to population and housing census, Gunsan-si has continuously shown increasing trend of vacant houses during 2015 to 2019. In particular, since Gunsan-si is the city which suffers from doughnut effect and industrial decline, problems regrading to vacant house seems to exacerbate. This study aims to provide a foundation of a system which can predict and deal with the building that has high risk of becoming vacant house through implementing a data driven vacant house prediction machine learning model. Methodologically, this study analyzes three types of machine learning model by differing the data components. First model is trained based on building register, individual declared land value, house price and socioeconomic data and second model is trained with the same data as first model but with additional POI(Point of Interest) data. Finally, third model is trained with same data as the second model but with excluding water usage and electricity usage data. As a result, second model shows the best performance based on F1-score. Random Forest, Gradient Boosting Machine, XGBoost and LightGBM which are tree ensemble series, show the best performance as a whole. Additionally, the complexity of the model can be reduced through eliminating independent variables that have correlation coefficient between the variables and vacant house status lower than the 0.1 based on absolute value. Finally, this study suggests XGBoost and LightGBM based machine learning model, which can handle missing values, as final vacant house prediction model.

Many houses have been left vacant in cities worldwide due to changes in the economy, society, and urban composition. The increase in vacant houses causes social problems and decrease in the value of real estate. Considering the cost of preparing a new residence because the existing residence no longer functions, it is an important problem to solve empty houses in the existing residence. Accordingly, policy attempts and studies to reduce and utilize vacant houses are in progress in various countries. In South Korea, the ratio of vacant houses was 6.4% of all houses as of 2021, and in Jeolla-buk-do, it was 11.6%, which is higher than the national average. Jeollabuk-do conducted a fact-finding survey on countermeasures against vacant houses; 17,732 vacant houses (2.4%) were surveyed. The urbanization, population, and terrain of Jeollabuk-do, consisting of 14 cities and counties, were considered. The ratios, types, grades, and spatial autocorrelations of vacant houses were analyzed after classification into city areas (focus, small, and medium) and county areas (plains and mountains) areas to derive policies according to the distribution of vacant houses. The average difference in ratio, type, grade, and spatial autocorrelation of vacant houses was used to analyze the characteristics of the distribution of vacant houses according to these classifications. There were significant differences in the averages of the ratios, grades, and spatial autocorrelations between city and county areas. The autocorrelation of vacant house distribution exhibited differences between urban and county areas.
