This extensive archive compiles over 1,200 pages of World War II materials, sourced from prominent US military archives. It features American propaganda leaflets used in the Pacific theater, along with related psychological warfare documents. These documents, some in Japanese and Korean with English translations, detail the strategic use of propaganda. The collection also includes Japanese leaflets aimed at Allied forces. The compilation comprises 730 leaflet images and nearly 500 pages of supporting documentation.

World War II highlighted the growing importance of psychological warfare in military strategy; a US Pacific Fleet report defines propaganda as a deliberate manipulation of enemy thoughts and actions to achieve military objectives, ultimately aiming to shorten the war and minimize casualties. The US Office of War Information (OWI) aimed to boost domestic morale and support the war effort. Its messages, disseminated via posters, radio, and the press, focused on initiatives like material donations, war bond purchases, women’s war work, resource conservation, and counter-espionage.

Conversely, the OWI’s Psychological Warfare Branch (PWB) targeted enemy populations. Its goal was to undermine enemy soldiers’ spirits and civilian support for the Axis powers through radio and print propaganda.

The OWI collaborated with the military on extensive WWII propaganda campaigns. Print and radio were the main tools, with leaflet drops becoming increasingly prevalent. Winkler’s book, “The Politics of Propaganda,” notes that the PWB dropped a massive number of leaflets in the Pacific, particularly in the final stages of the war against Japan. American leaflets distributed in the Pacific during World War II aimed to counter Japanese propaganda about mistreatment of prisoners, demoralize Japanese troops by highlighting Allied advances, evoke homesickness and anti-leadership sentiment among Japanese soldiers, convince them of the futility of continued fighting, encourage surrender by promising humane treatment, and showcase American military might.

Two 1944 reports from the US Pacific Fleet detail the strategies and tactics behind this propaganda campaign, including the creation and distribution of leaflets aimed at prisoner capture and demoralizing isolated units. These reports outline specific propaganda themes and distribution plans.

The reports provide guidelines for leaflet content, specifically advising against mentioning the Emperor and avoiding Japanese words for surrender and prisoner of war.

A supplementary document showcases example leaflets with explanations of their purpose, design, translation, and analysis. A later bulletin, number 164-45 from August 15th, 1945, provides further examples of psychological warfare leaflets distributed after two earlier reports.

Eight issues of the “Leaflet News Letter,” totaling 228 pages, were compiled by Area III’s Intelligence and Leaflet Unit between April 6th and September 1st, 1945.

This newsletter, typed and mimeographed, served as a resource for Far East-based military personnel involved in psychological warfare, specifically leaflet creation and distribution.

Recurring themes included analyses of past leaflet campaigns, leaflet writing guidance, and the involvement of prisoners of war in leaflet production. Articles covered diverse topics such as the airman’s role in psychological warfare, the treatment of past emperors, a beginner’s guide to leaflet writing, 8th Air Force leaflet operations, factors influencing Japanese soldier responses to Allied propaganda, and leaflets used in the Okinawa campaign.

Leaflet number 401, measuring 6 by 9 inches, depicts an American bomber approaching Japan. Its purpose was to undermine Japanese morale before anticipated American attacks. The image emphasized the futility of resistance, even on the Japanese home islands, due to the reach of American air power. The Japanese text on the back reinforced this message. Leaflet 2013: The recent bombing campaign and island conquests have instilled fear in Japan’s leadership, evidenced by their coastal defense preparations against an anticipated invasion. However, continued resistance is pointless; Japan’s military capabilities are no match for the superior American firepower and industrial capacity. The war is already lost for Japan.

Leaflet 2093: This leaflet, aimed at Japanese civilians, uses a familiar proverb to persuade them that surrendering is preferable to national devastation. The reverse side urges civilians to pressure their leaders into ending the war to stop the ongoing bombing raids, arguing that the military leadership’s continued fighting stems from self-preservation, not the well-being of the Japanese people. The battles of Saipan, Iwo Jima, the Philippines, and Okinawa resulted in significant Japanese military losses: 26,000 on Saipan, 23,000 on Iwo Jima, over 410,000 in the Philippines, and 105,000 on Okinawa.

The overwhelming American material advantage proved insurmountable for the Japanese, whose reliance on spiritual strength was insufficient. Despite any sympathy for the Japanese people, the Americans intend to continue the war until unconditional surrender. Okinawa now serves as a major airbase for attacks on Japan, with further expansion underway, creating a significant staging area for a mainland invasion. The invasion of Japan is imminent. Allied forces, victorious in Europe, are poised to invade Japan. The ensuing devastation from modern warfare will be unimaginable. Will Japan’s leaders continue fighting until total destruction? If so, Japan faces complete annihilation, a catastrophic loss of life.

However, Japan can avoid this fate by removing its military leaders and negotiating peace with the Americans.

As Americans committed to humanitarian ideals, we cherish humanity more than you do. Surrender will allow us to help rebuild a democratic Japan.
