Can anyone find the name of this man?

He survived the Hiroshima bomb explosion. He was just a child then, and the explosion trapped him inside his school. Then a soldier came and rescued him. As the soldier walked through the ravaged landscape with the boy in his arms, they heard the boy's father calling out to him. This was in a documentary I saw I think its on youtube but I can't find it. Another story it included was one where a women's child was trapped inside a bunch of debris. and the mother, who was so close to her child. had to hear her scream for help as she died. This was truly haunting. Both of these accounts bring tears to my eyes. If anyone could find the name of that guy, I will find some peace.
