Many disasters have been occurring in Japan, and along with each disaster a post-disaster restoration has been performed. It is necessary to put the lessons of these many experiences into good preparatory use for restoration in the future. In this study, the authors analyzed post-disaster restoration cases of the past, referring to existing study results, in order to examine exactly what such restoration should be. Thinking it is necessary to take not only the safety but also the local context, regional characteristics and regionality into consideration for such restoration techniques, the authors worked out the relationship between the restoration techniques and regionality in each case. Restoration in harmony with regionality or "symbiotic security" was then considered. As regarding regionality, four categories were set as natural areas (mountains, rivers, the sea, forests), industrial areas (fisheries, agriculture, brewing, sightseeing), community areas (cities, towns, blocks) and atmosphere of the town (streetscapes and landscapes), based on the idea that it should be necessary for reconstruction measures to place importance on the context of the neighborhood, the regionality and the local identity in the disaster-stricken area. Four important points were then listed for disaster restoration based on "symbiotic safety" from the examination ofregionality and three actual cases of disaster restoration (the 1993 Southwest of Hokkaido Earthquake, the 1991 Unzen-Fugendake Eruption, and the Niigata Prefecture Chuetsu Earthquake in 2004). The first point is to give a sufficient consideration to local characteristics and to include them in the existing planning; the second is to examine the characteristics of the stricken area that caused problems at the time of the disaster for the rebuilding measures. The third is town development in which the opinions of local inhabitants are taken into consideration - it is fundamental to pay attention to opinions from local residents and it is necessary for residents and the local administration to commit to town development in cooperation for maintaining regionality. The fourth is symbiosis with natural environments and sustainable development - such symbiosis with nature referring to the symbiosis with the natural environment that is peculiar to the neighborhood, which in turn leads to considerations for regionality of the district. Disaster restoration in harmony with regionality and with enhanced safety can be expected to be realized in the future if carried out based on the above-mentioned four points learnt through past cases.
