In the process of restoration following the damage caused by the Great East Japan Earthquake, Kumamoto Earthquake, and other disasters, a rapid population shift was seen. Therefore, this study investigated the effect of the risk of Nankai megathrust earthquakes, which are expected to occur within tens of years (with the Pacific coast area of Japan as a hypocenter), on population shift. .
Specifically, I considered the effect of residents’ recognition of an area from the viewpoints of safety and resilience on their intention of migration based on the risk of earthquakes. An online survey was conducted in October 2015, and about 6,300 persons living in the prefectures located from Kochi Prefecture to Kanagawa Prefecture responded. As a result of predicting a migration tendency by logistic regression analysis, it became clear that the regional views were specified by various factors, but it was also shown that the regional views had not necessarily influenced a migration intention. Therefore, assuming easily a population influx resulting from the risk aversion of a huge earthquake disaster to a local area needs to be warned. These findings may have great implications for national land planning covering a future wide area.

Japan is facing a declining population era. We have lately seen the growing phenomenon of reverse migration to rural areas, the process of “counter-urbanization,” as it is known. This counter-urbanization is recognized as a hope for many local municipalities because they struggles to maintain their scale of population. This analysis attempted to demonstrate economic effects of “Satellite office project”, a remote office in rural area in Kamiyama town through input-output analysis. It is because the project has contributed to increase migrants with information technology skills, which cannot been existed in the town before. The study also simulated future economic possibility of the Satellite office project with other major industries in the town.

This study aims to analyze the conceptual and spatial recognition to “Jimoto” of people by using an online survey data. The result showed that both recognitions of “Jimoto” were classified into several groups and each group had own feature. The result also showed these “Jimoto” consciousness were formed through the life events and daily lives of people. We also analyzed the relationship of these recognitions and undesired change to their “Jimoto”. The results indicated that people didn’t desire specific change if the connections between them and their “Jimoto” were formed by concrete objects or intimate people.
These “Jimoto” consciousness sometimes comes from outside of each region and spreads over administrative boundaries. This suggests the necessity of the systems that enable people to participate regional development projects from the outside or cooperation of several local governments.
