In 1989, Japan was perceived as an economic powerhouse, with its companies surpassing competitors and acquiring prominent American properties. However, a significant crisis loomed within the country as the government noted a drastic decline in the fertility rate, termed the “1.57 shock.” This decline raised alarms among policymakers, who warned of dire consequences if the trend continued, including increased taxes, diminished social security, reduced peer interaction for children, and a general loss of societal vitality due to a shrinking workforce. In response, Japan initiated various policies from the 1990s aimed at encouraging higher birth rates. These measures included mandating child care leave for employees, expanding subsidized daycare options, promoting paternal involvement in child-rearing, and offering direct cash allowances for families with children. Despite these efforts, Japan’s fertility rate has continued to decline, reaching an alarming 1.2 in 2022, with some areas like Tokyo reporting rates below one. The number of births recorded last year was the lowest since the government began tracking statistics in 1899. The situation in Japan reflects a broader trend observed in developed nations, where declining birth rates are becoming increasingly common. A 2019 United Nations Population Fund report indicated that half of the global population resides in countries with fertility rates below the replacement threshold of 2.1 births per woman. While low birth rates may not pose an immediate global issue, they can create significant challenges for individual countries, such as an aging population and a shrinking workforce. Experts like Tomáš Sobotka highlight the potential demographic crisis in countries like South Korea, where the birth rate is the lowest in the world at 0.72 children per woman. This demographic shift raises concerns about the sustainability of social support systems and economic stability as the working-age population struggles to support an increasing number of retirees. Similar issues are emerging across Europe and the United States, where declining birth rates lead to labor shortages and hinder economic growth. Governments worldwide are adopting measures similar to Japan's, including parental leave and financial incentives for families. The number of countries actively targeting birth rates has surged from 19 in 1986 to 55 by 2015. In the United States, the issue has surfaced in political discourse, with proposals from both Republican and Democratic leaders aimed at incentivizing family growth through tax credits and other financial support. Despite these initiatives, research shows that generous policies have yielded only marginal increases in fertility rates. Japan, in particular, has served as a case study, demonstrating that despite extensive efforts, families remain reluctant to expand. Experts suggest that profound societal changes may be necessary to alter preferences regarding family size, as many individuals prioritize career and personal goals over having children. Historical context reveals that low birth rates often stem from societal progress, such as increased access to education and employment for women and a shift away from agricultural economies. Rising living costs and the competitive job market further discourage larger families. As a result, parents tend to invest more resources into fewer children, leading to heightened competition for educational opportunities. Cultural expectations surrounding child-rearing roles also complicate the issue. In Japan, traditional gender roles persist, with women frequently bearing the brunt of child care responsibilities. Some countries have enacted policies to encourage paternal involvement, but these measures have not significantly increased fertility rates. Critics argue that incentivizing women to leave the workforce may not be a viable solution, as seen in countries like Finland and Hungary, which have also struggled to boost birth rates despite generous parental benefits. In response to declining marriage rates, Japanese policymakers are now promoting marriage as a means to encourage childbirth. However, the effectiveness of this approach remains uncertain, as many young adults face social and economic barriers to forming families. Efforts to improve wages and facilitate social interactions for young people are also being explored, but skepticism remains regarding the potential impact of such initiatives. Ultimately, influencing personal decisions about family size may be beyond the reach of government policies. The decision to have children is deeply personal and influenced by individual values, societal norms, and economic conditions. While certain policies can enhance the quality of life for families, they may not significantly alter fertility trends. In Japan, the visible demographic imbalance is evident, with a noticeable prevalence of older individuals compared to young families, highlighting the ongoing challenges posed by declining birth rates.
