A large number of A-bomb survivors were admitted to the hospital aid station at a branch of the Army Hospital attached to the Hiroshima Red Cross Hospital. The number is not known, but a large number of the injured poured in, some with severe burns from the August 6, 1945, explosion of the Hiroshima atomic bomb, and others on the verge of death on August 10. The room was filled with dying Hibakusha with burns on their faces and bodies, unable to wear clothes. Groans filled the large room, and even the water at their bedside could not be reached by themselves.
When the atomic bomb exploded on August 6, 1945, the Army Hospital Annex, which was attached to the Hiroshima Red Cross Hospital, was located about 1.6 kilometers south of the hypocenter. The three-story hospital ward was severely damaged, leaving the outer wall intact, but firefighting efforts prevented a fire. Only the exterior of the main building and other buildings remained, but the intense blast blew out the windows, and the interior of the building was a misery with debris scattered in the corridors. All of the X-ray films stored at the Hiroshima Red Cross Hospital were sensitized by the bombing, proving the radiation caused by the explosion of the atomic bomb. The city of Hiroshima was prepared for air raids, but the unprecedented explosion of the atomic bomb destroyed the city center, making it difficult to provide relief. First aid stations were set up in half-destroyed or slightly damaged national schools, temples, and private homes on the outskirts of Hiroshima.
Immediately after the explosion, the Hiroshima Red Cross Hospital was flooded with a large number of survivors, and treatment began. The Hiroshima Red Cross Hospital and the Hiroshima Hospital of Communications and Communication, which had sustained relatively little damage and whose medical functions were still intact, became the bases for relief centers in the city center. Later, the Hiroshima Atomic Bomb Hospital was established on the premises of the Hiroshima Red Cross Hospital in Senda-machi, Naka Ward, Hiroshima City, with about 65 million yen from the distribution of profits from the New Year's postcards with New Year's gifts in 1954 and 1955, and opened on September 20, 1956.
