After the end of World War II, Japan as a defeated country was seriously injured, not only soldiers died and were injured on the battlefield, but also 200,000 civilians died under the atomic bomb of the United States, so after the defeat and surrender of Japan not only collapsed economically, the population decreased sharply, so the top priority of post-war reconstruction is to quickly restore the population, for this reason Japan used a simple method, although effective but became the nightmare of countless female students.
At that time, in order to increase the number of people, Japan had promulgated many welfare measures, but because of the difficult life of the Japanese people after the war, no one was willing to have children at all, which led to their fertility rate has not been able to go up, when Japan found that the Soviet Union in the World War II population growth rate is very fast, so they decided to learn from the Soviet Union, that is, to adjust the age of marriage and childbearing of women.
Since ancient times, the population has always been closely related to the development of the country, especially in a resource-poor island country like Japan, if the population declines, then the social productivity will be greatly reduced, so Japan is eager to restore the population, when the Soviet Union lowered the age of marriage for women to sixteen years old, while Japan directly set the age of marriage and childbirth for women to thirteen years old.
After Japan lowered the age of marriage for women, many female students were forced to drop out of school to marry, and Japan also compulsorily stipulated that each family must have at least five children, so these female students must always have children after marrying, they themselves are still a child but they have become a pawn of the state, prematurely taking on the burden and responsibility of the family, although with this method Japan has restored the population to 100 million in a short period of time, but it has sacrificed the happiness of countless female students.
