It is interesting that in spite of the massive devastation caused by the tremendous impact of the atom bomb at Hiroshima, the majority of the characters ultimately appear to react to it in a very positive and inspiring way. This account describes the massive hardships and significant suffering that each of the main characters experience, and it is clear that the radiation sickness suffered by people such as Father Kleinsorge was immense. However, equally, the way in which he sought to do everything he could to use his gifts and talents for the benefit of those around him in spite of that suffering was massively hopeful and inspiring. For example, even though he had been instructed to rest, he did not strictly obey these instructions and had to be sent back to hospital for a month later on in order to recuperate fully. Note what the author writes about Father Kleinsorge, Mrs. Nakamura, Miss Sasaki, Mr. Tanimoto, Dr. Fujii, and Dr. Sasaki after the bomb at the end of this work:
One feeling they did seem to share, however, was a curious kind of elated community spirit, something like that of the Londoners after their blitz—a pride in the way they and their fellow-survivors had stood up to a dreadful ordeal.
Even though therefore the impact of Hiroshima is described in its full horror and terror, the power of the human spirit of these central characters is shown to be more than a match for the horrors of the atom bomb, and these characters rise to the challenge of rebuilding their lives and the lives of those around them and of Hiroshima itself.
