Abstract
This paper attempts to clarify effects of blood relationships with rural inhabitants on urban inhabitants' interests in rural and their resident areas. I conducted a questionnaire survey on the web with stratified sampling targeting both urban inhabitants and rural inhabitants all over Japan. 1,311 samples were collected, being divided into 3 groups, (a) urban inhabitants having blood relationships with rural inhabitants, (b) urban inhabitants without blood relationship and (c) rural inhabitants. I carried out Welch's t-test and analysis of variance to examine the significant differences between those groups. In the result, it was observed that urban inhabitants with blood relationships with rural inhabitants have higher interests in rural areas, as well as higher interests in their resident areas and higher social capital, which are close to rural inhabitants.
