Nagasaki: Life After Nuclear War by Susan Southard:
Nagasaki mayor Okada Jukichi had spent the night of August 9 atop a hill on the eastern border of the Urakami Valley, waiting in a panic for the fires below to diminish. At three a.m. on August 10, he made his way down the hill. In darkness lit only by scattered embers, he stumbled through debris and bodies to the place where his house had stood the day before, just a few hundred feet from the hypocenter. The soles of Okada’s shoes burned as he frantically combed through the hot ashes for his wife and children. Finding no trace of them, he hurried to the air raid shelter beneath his house to discover at least ten dead bodies, including those of his entire family. Simultaneously crazed and clearheaded, he proceeded to the next neighborhood over, where he identified the deceased family members of his deputy mayor.
