   A Hiroshima atomic bomb was dropped and exploded on August 6, 1945, and a boy was exposed to severe burns on his face and arms. Immediately thereafter, he was transported to and admitted into the relief station of Hijiyama National School. Hijiyama National School was located approximately 2.8 km southeast of the hypocenter and escaped the fire. Immediately after the atomic bombing, injured Hiroshima citizens were evacuated, and the school became one of the 13 relief centers declared by Hiroshima Prefecture on August 7.

　From August 8, Hijiyama National School became an evacuation center for lost children, especially small children, children who were not in diapers, children who had suffered severe burns, and children who had been seriously injured. The victimized children were rescued by four or five teachers and members of the local women's club.

　At night, the children woke up crying, saying, 'Mom, I want to go to the latrine. Inside the dark relief station, another child woke up and started crying. The child had diarrhea from the atomic bombing and could not wait long for the latrine, soiling herself on the way. The child soiled his bed without waking up. The next morning, blankets and mosquito nets soiled with bloody excrement were hastily washed by hand, dried in the sun, and used again in the evening. The small children who absorbed large amounts of radiation lost their hair due to alopecia, continued to suffer from diarrhea, grew thinner by the day, and finally died of atomic bomb sickness. They were cremated one after another in a corner of the schoolyard, and unleashed military dogs ransacked the corpses, waiting for the next incineration.

 　On August 8, two days after the atomic bombing, Hijiyama National School became the "Hijiyama Lost Children Camp" for orphans (called "lost children" at the time). At one time, about 200 children were housed there, but many of them died there of atomic bomb-related illnesses. The atomic bombing brought unprecedented chaos, and relief began for children whose guardians were not known to be alive or dead; by September 2, a total of 91 children (including 36 girls) were accepted, of which 40 were 0-5 years old, 47 were 6-12 years old, and 4 were 13 years old or older. Of these, 18 were taken in by their parents, 14 by relatives, etc. A total of 32 were taken in, but 9 died in the atomic bombings due to acute radiation injury from the bombs.
