Will Japan's Birth Count Fall Below 700,000? — Examining the Effectiveness of the ¥3 Trillion Declining Birthrate Policy

Introduction

Let us begin with the facts. According to preliminary vital statistics released by the Ministry of Health, Labour and Welfare in August 2026, the number of births in Japan from January to June 2025 stood at approximately 335,000 — a decline of about 4.2% compared to the same period the previous year. If this pace continues, the annual birth count will land in the 670,000–680,000 range, which would mark the first time since records began that the figure falls below 700,000. Birth numbers that exceeded one million as recently as 2015 will have dropped by more than 30% in just over a decade.

What Is Happening

The Children and Families Agency, established in April 2023, executed a budget of approximately ¥3.2 trillion in fiscal year 2024. Under the banner of an "unprecedented declining birthrate countermeasure," it rolled out policy after policy in rapid succession — including expanded child allowances (up to ¥30,000 per month for third and subsequent children), increased nursery school capacity, and free postnatal care. Yet the annual birth count for 2024 came to approximately 723,000, setting yet another record low, and the rate of decline shows no sign of easing.

On X (formerly Twitter), posts such as the following gathered widespread sympathy:

"These measures only target households already raising children. Support for people who simply don't or can't get married is virtually nonexistent. The policy is missing the root of the problem."

Calls to fundamentally rethink the design of benefit programs are growing louder.

Background

The structural causes of Japan's declining birthrate are multilayered. A 2023 survey by the National Institute of Population and Social Security Research found that unmarried individuals cited financial anxiety (57.3%) and lack of opportunities to meet potential partners (45.8%) as reasons for not marrying (or being unable to marry). The current policy framework has not adequately addressed the upstream issue of "marriage and partnership" that precedes childcare support.

Regional disparities cannot be ignored either. The total fertility rate in 2024 ranged from 0.99 in Tokyo to 1.60 in Okinawa Prefecture — a gap of 1.61 points. While high housing and education costs in urban areas suppress births, rural areas are losing the very population of women of childbearing age due to outmigration of young women. This is a problem intertwined with housing and employment policy, and it lies well beyond what the Children and Families Agency can resolve on its own.

Rather than simply being a matter of "insufficient budget for declining birthrate measures," this is closer to a structural problem of "poorly targeted policy design."

Key Points to Watch

The Limits of Cash-Transfer-Centered Approaches

The expansion of child allowances implemented in October 2024 is a large-scale measure generating an annual fiscal burden of approximately ¥1 trillion. However, OECD estimates suggest that declining birthrate measures centered on cash transfers have only a modest effect on fertility rates — on the order of 0.05 to 0.10. "Support after childbirth" is certainly necessary, but the view is becoming established among researchers that it alone is insufficient to reverse the decline in birth numbers.

The Upstream Problem: Declining Marriage Rates

The number of marriages in 2024 fell to approximately 472,000 couples — less than half the peak recorded in the early 1970s. In Japan, the share of children born out of wedlock stands at roughly 2.4%, the lowest among developed nations. Without legal frameworks supporting partnerships outside of marriage and broader social recognition of such arrangements, structurally increasing birth numbers is extremely difficult.

Disparities in Implementation Capacity Among Local Governments

Tokyo Metropolitan Government has continued its "018 Support" program, providing ¥5,000 per month to all children aged 18 and under since fiscal year 2024. However, municipalities with smaller fiscal bases often lack the capacity to pursue their own declining birthrate initiatives. A mismatch between national policies and local implementation capacity is one reason policy effects are not reaching people evenly.

Editorial Perspective

Having spent years reporting from regional bureaus, I can say that the issue of population decline is often one where "the gap between what the numbers show and what communities actually feel is larger than the figures suggest." Mayors of depopulated areas speak with a wry smile: "We know the young people are leaving. How many years have we been saying that?" The pattern — budgets accumulating in Tokyo while regional realities go unheard and policies are designed in a vacuum — has not changed.

In my view, declining birthrate measures need to be approached on two fronts simultaneously: as an economic problem and as a cultural and values-based problem. Economic support is a necessary condition, but not a sufficient one. Cultivating a sense that "having and raising children is something society rewards" cannot be purchased directly with a budget.

Those in Camp A, the "expand support" faction, argue: "Investment is still insufficient — we should raise spending to 3–4% of GDP, on par with Nordic countries." Those in Camp B, the "structural reform" faction, counter: "The issue is one of design, not of money — unless marriage, housing, and the way we work are reformed together, the numbers will not move." The moment calls not for abandoning either position, but for a composite approach that incorporates both perspectives.

Conclusion

If the 2025 birth count falls below 700,000, it will not be "within expected range" — it will be a visible demonstration that policy has failed to keep pace with structural change. Where has the annual budget of over ¥3 trillion flowed, who has it reached, and what has it changed? Cross-referencing Diet records with spending outcomes should be the starting point for thinking about what comes next. We hope this serves as an opportunity for readers themselves to reconsider what they want from declining birthrate policy.
