World War II was the largest war in history, when many countries were involved in the war and the losses were very large. Some countries have even suffered very hard, but the post-war recovery has been very fast, such as Japan. As the initiator of World War II, Japan was basically forced to take men to the battlefield, so after the end of the war, the country basically became a "daughter country", and post-war recovery became a problem.
At the end of the war, Because Japan was going to implement the plan of 100 million jade fragments, the United States finally dropped two atomic bombs on Japan, which caused a very huge blow to Japan. Most of the country's facilities were destroyed, and the economy fell to the bottom, almost collapsing. Recovery and development require a large number of laborers, so the war to restore the population has become the most important problem.
Japan borrowed the Soviet Union's method to lower the age of marriage for women, but the method used by Japan is very simple and loses the bottom line of human nature. In order to quickly restore the population to 100 million, Japan has lowered the marriage age for women to 13 years old! As a child at the age of 13, he didn't know anything, so he had to take on the responsibility of restoring the population. Moreover, the state stipulates that if you do not marry at an age, you will be punished.
After marriage, each family has at least five children, which is simply not a little human, and such a thing can only be done by Japan. And because the Japanese are deeply brainwashed by militarism, they will also follow the government's arrangements according to the government's regulations. Even some girls who do not accept it are eventually forced by the pressure of life and finally choose to marry. Eventually Japan reached the goal of recovering its population to 100 million, but such a method was too cruel.
