Black Rain (黒い雨, Kuroi Ame) is a novel by Japanese author Masuji Ibuse.

The novel is based on historical records of the devastation caused by the atomic bombing of Hiroshima.

They feel obligated to find a suitable husband for her, and by the start of the novel, three earlier attempts to arrange a match had already failed because of rumors that she had radiation sickness from exposure to "Black Rain," radioactive precipitation that had fallen when the immense firestorm caused by the nuclear explosion seeded the clouds over Hiroshima, causing the radioactive material to fall back down as rain.

Though Shigematsu's journal entries attempt to disprove his niece's sickness by demonstrating that she was not in Hiroshima during the blast, in the end it turns out that Yasuko had gone there immediately afterward to find her parents and was indeed sickened by the "Black Rain".

Director Shohei Imamura directed a film adaptation of the Japanese novel in 1989.
