Shōhei Ōoka (大岡 昇平 Ōoka Shōhei, 6 March 1909 – 25 December 1988) was a Japanese novelist, literary critic, and translator of French literature who was active during the Shōwa period of Japan. Ōoka belongs to the group of postwar writers whose World War II experiences at home and abroad figure prominently in their works. Over his lifetime, he contributed short stories and critical essays to almost every literary magazine in Japan.

The author's experience as a prisoner captured by American forces during WWII figures prominently in this haunting novel about the ultimate degradation of a man by war. Set in Leyte, where the Japanese army is disintegrating under the hammering blows of American forces, the story focuses on the disintegration of one man, Private Tamura. One by one, each of his ties to society is destroyed, until Tamura, a sensitive and intelligent man, becomes an outcast. Yet it is the novel's uplifting vision during a time of ultimate horror that has made it one of Japan's greatest novels.
