In Ibuse's book, he writes about the atomic bombing in Hiroshima and people's life after that. The story switches back and forth between these two periods. The scenes of those days in 1945 are so sorrow. The disaster brings out a world like a hell. The mushroom cloud actually lasts and shrouds over people's life, especially for those who are affected by radiation sickness. The black rain has stopped but it still remain formlessly in people's heart. However, there are still hopes in people's heart. People are trying to step out the black rain. The sentence in the end touches me. "If a rainbow appears over those hills now, a miracle will happen. Let a rainbow appear--not a white one, but one of many hues--and Yasuko will be cured." Even though the miracle won't indeed happen, the hope encourages people to carry on. If we take some color to represent the story, then when the atomic bombing happens, it turns out to be a totally black color. And it sticks on so strongly but still gradually fades into lighter color with the efforts of hope in people's heart. The longing of a rainbow of many hues indicates the hope of Shigematsu. The miracle for Yasuko may not happen, but the miracle of human will happen and the colorful life will finally come to true. The colorful life maybe represents a peaceful life. Wars that only bring disasters should end and the hope of peace will never vanish.
In the book, the narrator is kept in the world of sand. At first he tries all he can to escape. After all the failure out of his efforts, he finally seems to surrender but still obtaining the hope to escape sometime. However, from the first chapter of the novel, it has already been clear that even after 7 years he hasn't escaped. What have kept him from his hope of escaping even when he finally has the rope ladder to get access to the ground? Is that because of the found of the water trap? Or is that because of the woman's pregnant? The extreme situation in the fiction does represents the real situation for the society. There is non-shaped sand trapping us from the hope, from the ideal life. The non-shaped sand might be the realism. We are all being kept but can't escape from it. The more we struggle, the deeper we sink. Finally the best choice we can make is to surrender, to do nothing against it, and to get used to it. Individuals never can forbid the surrounding. How bitter is such a life in vain!
