Implications of Japan’s Strategy to Overcome Low Birthrate for Korea: Focusing on Case Studies in Nagi-cho, Okayama Prefecture, Japan

Purpose: Korea has the lowest birth rate in the world. We need to find measures to overcome the low birth rate. This is a key issue that will determine Korea’s survival. In this study, we would like to find measures to solve the low birth rate problem in Korea. Research design, data, and methodology: This study aims to understand in detail the various childbirth policies, strategies, and peculiarities that have been promoted, focusing on the cases of overcoming low birth rates in Nagi-cho, Japan. In addition, the substance cannot be grasped only through the contents introduced at home and abroad. We would also like to discuss the hidden truth of Nagi-cho. Hopefully, I hope that this study will be a useful hint in solving the low birth rate problem. Results: Now, Korean society is suffering from internal threats of low birth rates, not external threats. Just worrying doesn’t change the situation. Nevertheless, someone is responsible for identifying and predicting the nature of the problem from an objective perspective and raising an alarm in Korean society. Accordingly, the conclusion presented eight response strategies to overcome Korea’s low birth rate problem. Typically, the total fertility rate of 0.78 in 2022 is due to the fact that more than one child was not born between couples. In other words, the reason why the current number of births and fertility rates do not rise is not that they do not give birth to a second child, but that caused by not having a single child. Couples who give birth to their first child have a high probability of giving birth to their second child, but it is impossible to give birth to their second and third children unless their first child is born. It is the right childbirth policy to actively support couples who have given birth to a second child. Implications: We expect the sum of the partial optimizations to be equal to the sum of the total optimization, and this is what we are looking for in the implications 'best answer'. However, at the macro level of a country’s fertility rate, it is not easy to achieve the total optimum through partial optimization.
