Even though WWII in the Pacific was ended on 15 August 1945 (or at least the surrender was initiated then) and the surrender papers signed aboard the USS Missouri in Tokyo Bay on 2 September 1945 ("VJ Day"), there were many elements of the Japanese Army that took weeks and in some cases months to actually lay down their weapons and submit. (There are some rare cases of individual soldiers lasting for years and decades past the surrender, refusing to give in, living their lives in remote places.)
This document--"Headquarter / United States Army Forces Western Pacific / Public Relations Office / General Release - 47, APO 707, 23 September 1945"--released by the propaganda/public relations office of the U.S. Army Force Western Pacific, details some of the process of large forces of Japanese forces in the Philippines coming in to surrender.
Stating that 31,000 Japanese soldiers (and 17 generals) had already been placed under guard in Luzon's POW camps, the three-paragraph document ends with this interesting statement:
"No date has yet been set when it is expected all the Japanese in the hills will be in our hands."
