Yukio Kunihira

Yukio Kunihira, a photojournalist at the Mainichi Newspapers’ Osaka head office, entered Hiroshima on August 9, and that day took 40 photos (12 negatives of which remain) and three panoramic photos composed of a combination of several photos that still exist today. (Mr. Kunihira wrote in a personal account that he had used four to five rolls of film for his photography work that day). Two days later, on August 11, two of his photos, one of which captured a scene of relief supplies being carried into temporary prefectural offices, were published in the Osaka head office edition of the Mainichi Shimbun.
