Japan's Longest Day is a 1967 Japanese epic war film directed by Kihachi Okamoto. The subject of the majority of the movie is the period between noon on August 14, 1945, and noon on August 15, 1945, when Emperor Hirohito's decision to surrender to the Allies in World War II was broadcast to the Japanese people, and the attempted coup d'état to prevent that from happening. Film historian Joseph L. Anderson describes the film as "a meticulous reconstruction of the day Japan surrendered and thus ended the Pacific War.
