The Hiroshima atomic bomb was dropped at 8:15 a.m. on August 1945, and the explosion exposed a huge number of Hiroshima citizens to the bomb. 4-year-old girl was exposed to the bomb in Hiroshima City, and was left with burns and keloids on her left face and hands. The exposed girl was admitted to the Hiroshima Atomic Bomb Hospital on May 12, 1957, at the age of 16, to have the remaining scarring sequelae reshaped. After being admitted, the burns and keloids were formed by a surgical transplantation of skin from her thigh.
The girl, nicknamed Ms. Kintoki, was about 4 years old when she was exposed to the bomb while sitting on the porch of her home in Fukushima-minami, Hiroshima, about 2 kilometers from the hypocenter. She lost consciousness and became trapped underneath another house. He was rescued by a neighboring acquaintance, and on May 12, 1957, he was admitted to the Hiroshima Red Cross Hospital for plastic surgery. He underwent a total of nine plastic surgeries, including scars on his left neck, left anterior neck, and right elbow joint; after a skin grafting operation from his thigh to the affected area on October 21, he was strapped to the bed with a belt and cord because he needed absolute rest. Partial rest was not obtained and bleeding spots remained on the left cheek. The skin on both thighs was pulled off for grafting, and the scars remained and became ugly. On December 14, the girl was discharged from the hospital.
In 1954, the Hiroshima Atomic Bomb Hospital received a portion of the profits from the 1955 New Year's postcard lottery. The Hiroshima Atomic Bomb Hospital was set up on the premises of the Hiroshima Red Cross Hospital, which opened on September 20, 1956. In Nagasaki, the Atomic Bomb Hospital was established in May 1958 with a portion of the profits from the New Year's postcards. In 1957, there were many leukemia patients in the hospital's internal medicine ward and many young people undergoing plastic surgery for scars in the surgical ward; by 1967, the internal medicine ward was taking on more and more patients with malignant tumors and cancer.
