It uses the diaries of Japanese veterans, the newspapers and magazines at that time, military maps and photographs of the battlefield to reveal the nature of the war of aggression. The purpose of the museum is to reflect on the history of Japanese aggression and call for international peace. Reflecting on history and cherishing peace is worth visiting.
