Many of the affected cities of the Great East Japan Earthquake are aiming to form compact cities. The purpose of this research is to clarify the formation situation of compact city by reconstruction project of Yamamoto Town, Miyagi prefecture.
 Three investigations were made for this purpose. These are the relocation of residents and the transfer from outside the town after the disaster, the trend of new construction of houses around the newly developed areas, and the questionnaire to the residents of newly developed areas and their surroundings.
 Number of the people relocating in the town after the earthquake per area of habitable land is many in three newly developed areas and their surroundings. Among the three newly developed areas, especially relocation to the area around the New Yamashita station is remarkable. This tendency is similar about those who transferred from outside the town after the earthquake.
 Newly built houses around the newly developed area are increasing rapidly only after the earthquake in the vicinity of the area around New Yamashita station. This suggests that housing demand is concentrated here.
 As a result of questionnaires to residents around New Yamashita station and surrounding areas of New Sakamoto station and those surrounding areas, the following points were revealed.
 The most common reason for transferring to the newly developed areas or their surrounding areas is the convenience. Evaluation that it became "convenient" as the change of living is the highest. Therefore, it became clear that convenience is the most important reason for choosing residence. In addition, various support systems related to subsidies etc. are widely used. About 40% cite this as a reason for transfer. Therefore economic support is also a major incentive. On the other hand, as a change in living, only about 70% of people in the Yamashita and Sakamoto districts have decreased "close association".
 Convenience was very low in the sprawled urban area before the disaster. However, the convenience was dramatically improved by newly developing three urban areas, especially two places around JR station. This results not only in the newly developed areas but also in existing urban areas around these areas.
 In conclusion, it was confirmed that the formation of the compact city that Yamamoto Town aims for has given a certain effect in terms of concentration of residents and improvement of convenience. On the other hand, there are many people who think that "close association has decreased", and it became clear that the formation of the community is still insufficient. The challenge is how to create future communities of those who relocated and transferred to new urban areas away from the community before the disaster.
