This study aims to investigate and clarify the procedure of building evacuation projects implemented in the Japanese cities toward the end of the WW II. First, before March 1945, the Japanese government's insufficient acknowledgement of the damages inflicted by air raids upon cities resulted in little progress in evacuating buildings anywhere in the country, except in Tokyo. Second, comparison between the Tokyo and Kyoto cases after the massive destruction by air attacks in March 1945 revealed a change in the purpose and method of evacuation. Consequently, after the change, the evacuation appeared to be almost an auto-destruction of urban areas.
