Professor Chuta Tamagawa performed a pathological autopsy on a deceased Hibakusha in a board shed near the Hiroshima Teishin Hospital on October 11, 1945. He performed pathological autopsies on Hibakusha who were exposed to the Hiroshima atomic bomb dropped and exploded on August 6, 1945, and died of atomic bomb sickness at Hiroshima Teishin Hospital.

    Immediately after the atomic bomb exploded in Hiroshima, a temporary autopsy room was set up at the Hiroshima Hospital for Disaster Relief to perform pathological autopsies on A-bomb survivors who had died of atomic bomb-related diseases. The temporary autopsy room was part of a ward set up in a rapidly increasing number of hospitals to isolate A-bomb survivors suspected of having dysentery based on the use of blood in their stools. After being released from suspicion of dysentery, it became a temporary autopsy room.

　Professor Chuta Tamagawa performed pathological autopsies on deceased A-bomb survivors on October 11, 1945 in a board shed near the Hiroshima Teishin Hospital. He was exposed to the Hiroshima atomic bomb when it was dropped and exploded on August 6, and died of atomic bomb sickness at Hiroshima Teishin Hospital. Professor Tamagawa of the Hiroshima Medical College recorded the pathological autopsies of A-bomb survivors from August 29 to October 13. As his assistant, Dr. Shuzuo Miyasho of the Department of Internal Medicine recorded the pathological autopsy.

　Autopsy records of pathological autopsies of A-bomb victims survived from immediately after the atomic bomb exploded and destroyed Hiroshima on August 6. Professor Tamagawa of the Hiroshima Medical College conducted 19 pathological autopsies between August 29 and October 13, and all of the autopsy records have survived. The autopsies were conducted in a wooden hut near the Hiroshima Teishin Hospital (Naka Ward, Hiroshima City). The autopsies became a valuable record of pathology examining the early effects of radiation from the atomic bomb. They are kept by the Molecular Pathology Laboratory of the Graduate School of Molecular Pathology, now Hiroshima University, which had Prof. Tamagawa as its first professor.

 　Tamagawa (1897-1970) was transferred from an assistant professor at Okayama Medical College to a professor at Hiroshima Medical College in the spring of 1945, following the approval of the Hiroshima Medical College. on August 6, he was in Akita Takata City, the current site of the evacuation of Hiroshima Medical College. on August 8, he entered Hiroshima City. He asked the Hiroshima Prefectural Government for permission to perform a pathological autopsy, but was denied.

 On August 27, he left for Hiroshima City again, saying, "I have received reports of alopecia, subcutaneous hemorrhage, and a series of unknown lesions, so there is not a moment to lose. He requested the cooperation of Michihiko Hachiya, a junior colleague at Okayama Medical University and director of Hiroshima Telecommunications Hospital. Director Michihiko Hachiya put up a notice in the hospital warning against "atomic sickness" and felt the need for a pathological autopsy. Professor Tamagawa performed the pathological autopsy in a wooden barracks that had been built by the Ujina Army Ship Command's Dawn Unit in the backyard of Hiroshima Teishin Hospital. By October 13, he had dissected 19 cases. The hospital doctors who had been demobilized and students from Okayama Medical University who had come to help served as assistants and wrote down their dictations.

　The paper, "Autopsy Records of 19 Cases of Atomic Bomb Sickness in Hiroshima City," was published in the Science Council of Japan's "Report on the Atomic Bomb Disaster," which was published in 1953 after the end of the GHQ occupation. Professor Tamagawa of the Hiroshima University School of Medicine discovered cancer transformation in the epidermis of patients with keloids from the atomic bombing, and pathology and tissue specimens confiscated by GHQ were returned to Japan from the U.S. Army Institute of Pathology in 1973 and kept by the former Hiroshima University Institute of Original Medicine and others.

These keloids cover the backs of Nagasaki atomic bomb survivors taken between 1945 and 1950. The burns and wounds of atomic bomb survivors resulted in thickened scars and tumors called keloids.

　Keloids covered the backs of Nagasaki atomic bomb survivors. Keloids are dense fibrous growths that grow over scar tissue; these keloids covered the backs of Nagasaki atomic bomb survivors taken between 1945 and 1950 (date, time, and location unknown).

　 Tumors, called keloids, developed from the burns and wounds of atomic bomb survivors due to the thickening of scars. Keloids occurred in approximately 50-60% of those exposed to heat radiation within 2 km of the hypocenter. Keloids are related to radiation. Keloids left permanent scars on the victims' minds and bodies. Those with keloids, especially on their faces, suffered even more emotionally, while those with keloids on their backs and shoulders were hesitant to show their skin.

　　Keloids are irregular, abnormally protruding scar tissue formed during the healing process of burned skin of A-bomb survivors. The name comes from the fact that the scars look like the shell or legs of a crab. Most commonly seen in survivors within about 2 km of the hypocenter, keloids formed four months after exposure and became most prominent six to 14 months thereafter. Most scars shrank and healed after about two years.

　At 11:02 a.m. on August 9, 1945, in the waning days of the Pacific War, Fat Man, an approximately 21-kiloton detonation-type atomic bomb with plutonium as its core, exploded about 500 meters above Nagasaki. An estimated 70,000 Nagasaki citizens were killed and some 60,000 injured. The bomb exploded over Nagasaki City, an industrial city in the densely populated western part of Kyushu. The surrounding hills prevented the devastating effects of the atomic bomb from spreading over Nagasaki City. On the contrary, they concentrated the destructive power of the atomic bomb, making it more intense in the areas closest to the hypocenter. The Nagasaki atomic bomb obliterated hospitals and medical schools located within approximately 914 meters of the hypocenter. People within a radius of 1.5 km from the hypocenter disappeared in an instant. 

In early October 1945, surviving residents of Hiroshima City wandered the cleared streets, bisecting the ruins. The city was reduced to a pile of rubble by the atomic bomb that had been dropped and exploded on Hiroshima City approximately two months earlier.

　　In early October 1945, surviving residents of Hiroshima City wandered the cleared streets, bisecting the ruins. The city was reduced to a pile of rubble by the atomic bomb that had been dropped and exploded on the city about two months earlier.On August 6, 1945, an atomic bomb was dropped on Hiroshima, killing an estimated 90,000 to 120,000 people by December of the same year. In 1945, Tokyo and other cities had already been thoroughly bombed by the U.S. military.

　Homer Bigart, a reporter for the New York Herald Tribune, was allowed to enter the city of Hiroshima on August 6, after the U.S. military had dropped and exploded the atomic bomb, with a delay of September 3. Accompanied by Bernard Hoffman, a Life Magazine photographer who had photographed the bombed area, we walked through Hiroshima on September 3. Hibakusha from the first atomic explosion about four weeks earlier died at a rate of about 100 per day around September 3 from burns and infections that were difficult to treat. The toll from the atomic bomb, the deadliest nuclear weapon in history, was approximately 53,000 dead, 30,000 missing, 13,960 seriously injured, and 43,000 wounded. Homer Biggard considered it a logical act of war to annihilate the enemy Japanese forces, even as he witnessed the destruction of the city of Hiroshima one month after the atomic bomb exploded over the city on August 6, 1945. Bigard won Pulitzer Prizes for his coverage of the Pacific War in 1945 and the Korean War in 1951.

　The city of Hiroshima was just a flat, horrifyingly desolate landscape. The desolation was accentuated by bare, blackened tree trunks and the occasional shell of a reinforced concrete building. Debris was everywhere, but its size was much smaller than usual. The atomic bomb demolished everything. Only a few shells remained of buildings made of iron and steel. Most of Hiroshima's wooden structures were burned to the ground. Japan was in an all-out war. The war had to be won, and they felt they had to virtually exterminate the enemy.

The area around the hypocenter where the atomic bomb exploded in Hiroshima on August 6, 1945, collapsed. All occupants of the bus, which was set ablaze by the hot air from the atomic bomb, were killed. Soldiers from the U.S. occupation forces surveyed the damage caused by the Hiroshima atomic bomb in September 1945.

     At the end of World War II, the area around the hypocenter where the atomic bomb dropped on Hiroshima by the U.S. military on August 6, 1945, collapsed. All occupants of the bus that caught fire due to the hot air from the atomic bomb were killed. The fire damage caused tremendous loss of life. Soldiers from the U.S. occupation forces surveyed the damage caused by the atomic bomb in Hiroshima in September 1945.

　Immediately after the bombing, the firefighting and rescue teams were stripped of personnel and equipment, making the worst of the damage. More than 90% of the citizens of Hiroshima who were within about 500 meters of the hypocenter were killed; it is estimated that about 140,000 people, most of them civilians, died as a result of the atomic bomb blast that was dropped and exploded on Hiroshima on August 6, 1945. About half of those who died in the bombing were killed instantly, many of them literally vaporized by the heat rays. The U.S. Atomic Bomb Survey team entered the city of Hiroshima in September 1945 to conduct research.

　In September 1945, after the atomic bombs were dropped and exploded in 1945, Bernard Hoffman became the first American civilian photographer to be at the sites of the bombings of Hiroshima and Nagasaki. His photographs offered a glimpse of the devastating destructive power of the atomic bombs, and were published in the first issue of Life magazine in 1936. It was a photograph of the scene of Hiroshima after the atomic bombing. Soldiers from the U.S. occupation forces surveyed the desolate, charred wreckage of a bus in which an atomic bomb had been dropped and its occupants had perished.

The August 9, 1945 explosion of the Nagasaki atomic bomb derailed a streetcar that was destroyed by the blast and burned in early September 1945 near Urakami Station, about 1.5 km south of the hypocenter.

The August 9, 1945 explosion of the Nagasaki atomic bomb derailed a streetcar that was destroyed by the blast and burned in early September 1945 near Urakami Station, about 1.5 km south of the hypocenter. Approximately 16 of the approximately 63 biaxial cars of the tramcar were destroyed by the Nagasaki atomic bomb.

　The bombed area, centered on Urakami in Nagasaki, was a burnt-out area. In addition to the wreckage of the streetcars, there was also the overturned and burned wreckage of automobiles. Both sides of the railroad tracks were covered with debris. The bombed area in Nagasaki City was a long, narrow basin from north to south, surrounded on the east and west by mountains. Urakami Station was located approximately 1 km from the hypocenter. The station building was completely destroyed and many bodies were scattered around the premises. The casualties among JNR employees were also enormous: 65 of the approximately 70 employees on duty were killed, including 20 who died instantly.

　Nagasaki Electric Railway Company (Nagasaki Dentetsu) suffered severe damage to its main facilities, buildings, vehicles, and employees, with an approximately 3 km section between Nagasaki Station and Ohashi destroyed. The entire line in the former city was also shut down for several months. About 21 cars were destroyed by fire, 120 utility poles were toppled and broken, several power lines and tracks were destroyed by fire, and more than 100 employees were killed. The company was forced to suspend operations due to the inability to operate trains. Of the 56 cars owned by the company, about half were movable cars, and the deaths of employees (including mobilized students and female volunteers) accounted for 23% of the total of about 500 employees. On November 24, three months after the Nagasaki atomic bomb was dropped on August 9, 1945, streetcars again began running through the streets of Nagasaki. 

A 32-year-old woman engaged in agriculture, who had been exposed to the Nagasaki atomic bomb and was rescued at the Omura Naval Hospital, was hospitalized on September 11, three days after the bombing on August 9, in the fourth sick bay, with general weakness.

　　　A 32-year-old woman who was engaged in agriculture was injured by the Nagasaki atomic bomb and was admitted to the Omura Naval Hospital. Three days after the bombing, on September 11, she was admitted to the hospital in the fourth ward. On September 21, her erythrocyte sedimentation rate rose to about 100 mm per hour. No other indication was given and there were no articles recorded.

　　Immediately after the Nagasaki atomic bomb was dropped and exploded, the Nagasaki City Medical Association and other relief teams began medical relief activities from the area around the hypocenter. The main relief stations in the old city center of Nagasaki were the Shinkozen Elementary School relief station and the Katsuyama Elementary School relief station. The relief stations on the opposite shore were Inasa Elementary School, Mitsubishi Hospital (main hospital), and Goshinji Temple. In northern Nagasaki, a private house in Hiramune (now Nameshi 1-chome) was used as a relief station. In the surrounding area, the families of veteran military doctors were notably rescued.

　　Only an hour or two after the Nagasaki atomic bomb exploded, Nagasaki Medical College employees began treating the injured who had been exposed to the bomb in the hills behind Nagasaki Medical College Hospital. Four to five hours later, the first team of the Isahaya Naval Hospital rescue team began treating the injured who had been exposed to the bomb at Irabayashi Elementary School. A rescue team from the Omura Naval Hospital and a rescue team from the National Obama Clinic (Obama Town Rescue Team) also entered the hypocenter area of Nagasaki City and carried out rescue activities.

　　In Nagasaki City, dedicated relief efforts were carried out in and around the hypocenter immediately after the bombing. However, the scope of their activities was limited to a few areas. The arrival of relief teams was delayed under the worst possible conditions, with frequent air raid warnings and American fighter planes flying overhead. The start of full-scale medical relief activities was also delayed until August 10, the day after the Nagasaki atomic bomb was dropped. from August 10, relief teams from inside and outside Nagasaki Prefecture, including many Marine and Army relief teams and relief teams from various universities, arrived in the disaster area and were able to provide active relief. The organization of the relief units of the Imperial Japanese Navy and the Imperial Japanese Army gave priority to Nagasaki natives selected as officers and medics. It appears that soldiers from Nagasaki who worked under their command were also enlisted. The IJN and Japanese Army relief units mobilized to work in the devastated, bombed-out city of Nagasaki, university relief teams, and relief teams from inside and outside of Nagasaki Prefecture were engaged in relief efforts.

A 3-year-old Japanese girl was burned by the Nagasaki atomic bomb, and walked around with a bandage on her head on September 29, 1945. She was injured near her destroyed home, about 1.9 kilometers south of the hypocenter of the Nagasaki atomic bomb.

　The detonation of the atomic bomb resulted in the appearance of a huge fireball. The fireball was about 100 times brighter than the sun and its center was several million degrees Celsius. The fireball was about 100 times brighter than the sun, and its center was several million degrees Celsius. It released intense heat rays, fierce blasts, and enormous amounts of radiation, and instantly set a wide area on fire, centered on the hypocenter. The heat rays caused the surface temperature of the ground at the hypocenter to reach approximately 3,000 to 4,000 degrees Celsius. The intense heat rays caused severe burns to the survivors, and many people were killed or injured. Fires that broke out immediately after the bombing also caused extensive damage and destruction.

　Damage caused by the Nagasaki atomic bomb (estimated by the end of December 1945)* The estimated population of Nagasaki City at that time was approximately 240,000 (rationed population as of May 31, 1945), of which 73,884 were killed and 74,909 were injured. (Report of the Committee for the Preservation of Atomic Bomb Materials (released in July 1945)) A girl who suffered burns on her head from the Nagasaki atomic bomb was searching and rummaging around in the rubble ground of the ruined Nagasaki City.
