Mount Hakkoda

Mt. Hakkoda is a 1977 Japanese film directed by Shirō Moritani. Based on the novelist Jirō Nitta's recounting of the Hakkōda Mountains incident, the film tells the story of two infantry regiments of the Imperial Japanese Army, consisting of 210 men, that tried to traverse the Hakkōda Mountains in the winter of 1902, in preparation for the anticipated Russo-Japanese War. The film was Japan's submission to the 50th Academy Awards for the Academy Award for Best Foreign Language Film, but was not accepted as a nominee.
