In Japan, young people tend to move to urban areas in search of jobs as the declining birthrate and aging population progresses. As a result, the aging of the population in rural areas is progressing and it is difficult to maintain the communities. In order to break this situation, appropriate measures are needed. It is important that young people stay in a rural area. They are the next generation. It is very difficult to derive fundamental measures to stop the declining trend of Japan’s total fertility rate. However, it would be possible to keep the rate of decline low. If some measures are not taken immediately to stop the outflow of young people to urban areas, many rural areas may rapidly disappear. This trend is an issue that is also consistent with other countries, and it is desirable to develop measures as a model for the world. The Population Strategy Council announced “744 municipalities having the risk of disappearing.” Several local governments (rural areas) in Hokuriku are included in this category. The governments that are far from the prefectural capital tend to fall into this category and many social infrastructures tend to be concentrated near prefectural capitals. In this paper, an increase of a “connected population” (Kankei Jinkou in Japanese) is proposed as one of the measures to avoid becoming a disappearing local government. The possibility of regional revitalization is created due to the measure. It can be also expected to ease the population decline rate to some extent. This is consistent with Goal 11 of the SDGs (Sustainable Cities and Communities). Nanto City, Toyama Prefecture, which was listed as municipalities having the risk of disappearing, is selected as the research area.
