The purpose of this study is to develop a quantitative estimation procedure for disaster debris in consideration of seismic retrofitting of dwelling housing by accounting for the relationship between the time of construction, fragility curves of housing, and the result of earthquake resistant evaluation. The developed estimation method was applied to the 2016 Kumamoto earthquake disaster, and the amount of disaster debris was estimated to be 2.96 million tons with consideration of seismic retrofitting. In addition, the amount of disaster debris caused by the Nankai Trough Earthquake disaster in Aichi Prefecture was calculated. As a result, it was indicated that reconstruction and seismic retrofitting of dwellings could result in the reduction of disaster debris.
