日ソ中立条約
In May, 1943, the IJA 74th Infantry Regiment was separated from the 19th Division and was elevated to become the core of the new 30th Division. As the situation for Japan continued to deteriorate for Japan in the Pacific War, a decision was made to trust in the Soviet–Japanese Neutrality Pact, and reduce forces held back in reserve against the Soviet Union. In December 1944, the remainder of the 19th Division was transferred to the control of Japanese Fourteenth Area Army in the Philippines. The 19th Division was subsequently largely annihilated in combat in the mountains of central Luzon during the subsequent Battle of Luzon from January 1945 and ceased to exist a functional unit at that time.
