There are a lot of wooden cultural heritages in Japan and fire prevention measures are considered as basics of disaster mitigation for cultural heritages. On a high densely area of wooden cultural urban city, it must be hard to control fire spread and it can be a large-scale fire after the earthquake. This study evaluated the risk of fire simulations of historic buildings were destroyed, including buildings that are not designated existing temples in Kyoto and to extract the risk of historic buildings and urban areas.
