In the Record of the "Nagasaki A-bomb War Disaster", those close to the hypocenter (Matsuyama township), were described as all having been killed, with the exception of "a child who was in an air-raid shelter." A little further away, Professor Seiki of Nagasaki Medical School Hospital was building an air-raid dugout 400 m from the hypocenter of the detonation and survived. Chimoto-san, who was atop a distant hill that creates the valley in which Nagasaki is located, performed the similar "" maneuver upon seeing the bomb drop, which was notably "prior" to the detonation. However despite having these few seconds of relatively unique warning, he did not stay on the ground for long enough after the "flash" subsided, and received some translational injuries due to prematurely standing-up again, at which point the slower moving blast wave swept past him and carried him with it for a few meters.
