Sunao Tsuboi's experiences at Hiroshima
Tsuboi was 20 years old when the United States dropped an atomic bomb on his hometown on August 6, 1945. He was on his way to engineering school when the bomb hit, killing 140,000 people.
Three days later, a second nuclear bomb fell on Nagasaki, killing another 70,000 people. Japan formally surrendered on August 15.
"I suffered burns all over my body," Tsuboi said in 2016. "Naked, I tried to run away for about three hours on August 6 but finally could no longer walk."
He gained consciousness 40 days after the bombing, but he was so weak that he had to start by crawling. A part of his ear was gone because of the burns. Later, he developed cancer and other diseases.
