Emperor Meiji and the Great Russo-Japanese War (1957)

Meiji Tenno portrays the buildup to the Russo-Japan War. In addition to showing the political events that led to war, it also shows the era from the story of a farm family in rural Japan that sends their son off to war. As such, it could be considered an anti-war movie, showing how, while war is devised by governments, the people do not really understand what war is, and its combatants often do not know what they are fighting for.
