This study analyzes the realities of the separation of disaster-stricken villages by the collective relocation project and its impact on residents. We conducted a questionnaire survey for residents of Nishidani district in Nagaoka city. Clarified points are as follows; 1) To remain or to relocate was depending on the decision of each household. However, there was a trend that large households had relocated, and elderly single or couple households had remained. 2) The original villages were not only decreasing the population but also having uneven distribution of small elderly households. Especially in peripheral areas of the villages, more unfavorable conditions had happened. 3) On the other hand, relocated households generally showed higher intention of settlement and more life satisfaction, even though, many of them did not break up the relationship with their former living places.
