Japan's Longest Day (日本のいちばん長い日) is a 1967 Japanese War film directed by Kihachi Okamoto. The subject of the majority of the movie is the period between noon on August 14, 1945, when Emperor Hirohito made the decision to surrender to the Allies in World War II and noon on August 15, 1945, when the emperor's recorded message announcing the surrender was broadcast to the Japanese people. Joseph L. Anderson describes the film as "a meticulous reconstruction of the day Japan surrendered and thus ended the Pacific War.
