抄録

This article is to explore the reality of a voluntary relocation to a higher area and its context in the coastal areas with high Tsunami disaster risk. We carried out a questionnaire and interviews to the households that actually moved, and had the following results. 1) The relocation motivated only by concerns about Tsunami has also underlying concerns about the relocation itself, which tends to become obvious as difficulties to sustain their prior lifestyle. 2) To sustain their lifestyle, there are three approaches to secure mobility such as self-driving of their own cars, use of transportation service, and support by their neighbors and relatives. 3) On the other hand, close neighborly relationship tends to be lost in accordance with the relocation, particularly among the elderly population, and it leads the loss of one of these channels in securing of mobility.
