Asahi city in Chiba prefecture was suffered extensive damages by tsunami in the Great East Japan Earthquake. Iioka area where was damaged by the largest tsunami in Asahi city is outside of City planning area. In this area, the form of ”local reconstruction” was taken. It didn’t perform the regulation of land use except the development of a new evacuation routes and towers. The purpose of this study is to reveal how residents suffered damage in affected area by tsunami moved or reconstructed and what kind of conditions affect local reconstruction. Through this study, we revealed that in Iioka area, most households repaired their house in the same area. The recovery rate of building in inundation area is 60.7%, partially destroyed building and commercial-based building were relatively high. Reduction of the building of the city block facing the sea is the most intense. It cannot be said to have improve the living environment in affected area by tsunami. Because the measures for land use and living environment has not been taken, to promote low-densification of the area and making it difficult to community regeneration. Necessity of land utilization program decision of the area level in which an infrastructure building was placed was suggested.
