Japan's Demographic Dilemma: Navigating the Postpandemic Population Decline

Area of Science:

• Demography
• Public Health
• Sociology

Background:

• Japan is experiencing a significant demographic crisis, marked by a 1.5% population decrease by 2022 and the highest excess mortality rate among OECD countries.
• The crisis is primarily driven by an aging population, with Japan's aging rate at 29.9%, the highest among peer nations.
• The COVID-19 pandemic has further exacerbated Japan's demographic challenges.

Purpose of the Study:

• To analyze the effectiveness of Japanese government policies aimed at addressing the demographic crisis, particularly those focusing on increasing fertility rates.
• To evaluate the potential impact of financial interventions on Japan's population by 2060.
• To identify key societal factors that need to be addressed for a sustainable solution to Japan's demographic decline.

Main Methods:

• Evidence-based policymaking (EBPM) analysis was employed to assess the impact of proposed policies.
• Quantitative analysis was used to estimate the population increase resulting from financial interventions by 2060.
• Qualitative assessment of societal factors, including gender norms and workplace culture, was conducted.

Main Results:

• The EBPM analysis indicates that the anticipated impact of current policies on fertility rates is marginal.
• Financial interventions are projected to result in only a slight population increase by 2060.
• Societal issues such as gender norms and workplace culture were identified as crucial for a sustainable demographic strategy.

Conclusions:

• Current fiscal policies alone are insufficient to effectively combat Japan's demographic decline.
• A comprehensive approach integrating broader societal changes with fiscal measures is essential for addressing Japan's demographic crisis.
• Addressing gender norms and workplace culture is critical for achieving sustainable population growth and mitigating demographic challenges.
