4. The Fall Back of the Front Lines and Asia

In July 1944, Saipan—which had been designated as being within the Absolute National Defensive Sphere—fell, and bombing raids on the Japanese home islands intensified. Japan’s attempt to invade British India from Burma in the Battle of Imphal (March–July 1944) failed, and U.S. forces landed in the Philippines in October 1944. Fierce urban combat took place in the capital Manila from February to March 1945.

During the Pacific War, Japan’s policy toward French Indochina was “maintenance of tranquility” by refraining from interfering in its internal affairs . However, following the collapse of the pro-German government in France and the defeat in the Battle of the Philippines, the Japanese military launched an operation to disarm the French Indochinese forces beginning on March 10, 1945. This document is an excerpt from the “Confidential War Diary” entry for that same day.

The “Confidential War Diary” was a journal kept by staff officers (staff members) of the War Guidance Section, Army Department, Imperial General Headquarters, from June 1940 to August 1945.

While Army headquarters considered a “military solution” regarding Thailand, Ambassador Yamamoto in Thailand and Tōgō Shigenori, Minister for Foreign Affairs and Minister for the Greater East Asia Co-Prosperity Sphere, opposed this. The image shows a draft outline of Minister Tōgō’s remarks at the Supreme War Guidance Council meeting on July 17. It notes that Germany’s surrender and the fall of Rangoon had shocked the Thai people, leading to a growing reluctance to cooperate with Japan; however, they were generally still complying with Japan’s requests. It also states that a military solution would shatter the unity of the Greater East Asia Co-Prosperity Sphere and was highly likely to provoke a general uprising among the Thai people.
