This study aims to clarify the change of human relation in the nighbourhood by the space restructuring system thorough the earthquake disaster rehabilitation land readjustment project. We made a questionnaire survey on the residents at the Misuga district, Kobe City where the project was enforced. Clarified points are as follows: 1) Changes made by spatial restructuring through urban area reconstruction project have several levels, some households being affected significantly while others aren't. 2) Significantly influenced households are more likely to lose the relationships they had with their neighbors before the earthquake. 3) They lose relationships with their neighbors because of the changes in housing types and the distance between domiciles. By losing the relationships with neighbors, residents go out less frequently, and they tend to "shut-in". 4) They are mainly small households. Many of them used to have relationships with neighbors who have different types of households.
