(Bonus) In the period just before and during World War II, propaganda in Imperial Japan was designed to assist the regime in governing during that time. Many of its elements were continuous with pre-war themes of Shōwa statism, including the principles of kokutai, hakkō ichiu, and bushido. New forms of propaganda were developed to persuade occupied countries of the benefits of the Greater Asia Co-Prosperity Sphere, to undermine American troops' morale, counteract claims of Japanese atrocities, and present the war to the Japanese people as victorious. It started with the Second Sino-Japanese War, which merged into World War II. It used a large variety of media to send its messages.
