This paper outlines the “Teito-sokai-jigyo-ippanzu” (General Map of the Tokyo Metropolitan Government’s Building Evacuation Project), which shows the entirety of the Tokyo Metropolitan Government’s building evacuation project from the first to the fourth phases, and the “Tatemono-sokai-chikuzu” (Building Evacuation District Maps), which shows the project for each ward. Both maps were published in May 1944 by the Building Evacuation Division of the Tokyo Metropolitan Government’s Defense Bureau, and show a total of 357 evacuated areas.
