Abstract
This paper, taking the river basin area of San-En-Nanshin Region as a case study, aims to clarify the urban resident's interest in living in the mountainous region as well as the current situation and expectation in the rural areas towards receiving new residents. The results are as follows. It was confirmed that there are many urban residents with hopes of moving to the mountainous region. It was also confirmed that there are villages in the mountainous region with a past record of immigration from urban areas, and that the village leaders intend to receive more urban residents in the future. In this research, it is clarified that to promote settlement or temporary stays by urban area residents in mountainous regions, an approach considering the downstream urban areas and the mountainous regions within the same river basin under one framework can be an effective method.
