Immigrant genocide

After the Japanese occupation of Korea, it carried out the same genocide policy as China, which constituted a national policy of effective immigration and population change. Japan occupied the Korean peninsula from 1905 to 1945 when Japan was defeated, totaling more than 40 years. During the 40 years of Japanese occupation, genocide and bloody slaughter were carried out. I can't help wondering why 1945 the Korean population on the Korean peninsula is 40 million. That is, in 40 years of genocide and bloody slaughter, the population has doubled? I tried to search the statistics of the number of Japanese prisoners and overseas Chinese evacuated from the Korean peninsula after Japan's defeat, but there were no relevant statistics. Then, from 65438 to 0945, the Korean population on the Korean peninsula was 40 million, and how many of them belonged to authentic Korean descendants? How many are descendants of authentic Japanese expatriates [Japanese war immigrants]? How many products are there from the hybridization between two ethnic groups? Assuming that Japanese war immigrants or their descendants deliberately stayed on the Korean peninsula in 1945, pretending to be deaf or dumb, or pretending to be illiterate and speak only a few simple Korean words, or pretending to be Koreans living in the old forest of Moriyama to gain sympathy, it is impossible to quickly identify their nationality at that time. Excuse me, why did Japanese war immigrants deliberately stay on the Korean peninsula? What is the real origin of the civil war on the Korean peninsula? Is today's history really thorough? The civil war on the Korean peninsula, the ultimate beneficiary country: Japan. Because of the civil war on the Korean Peninsula and the Sino-American Korean War, Japan benefited from the post-war economic rise.
