What's happened
Japan's birthrate decline slowed in 2025, with births rising for the first time since 2021, while South Korea's fertility rate increased to 0.80, supported by government incentives and rising marriage rates. Both countries face long-term demographic challenges.
What's behind the headline?
The recent upticks in Japan and South Korea's birthrates suggest that policy measures and social shifts are beginning to influence demographic trends. Japan's slowdown in decline and South Korea's rise in fertility rate to 0.80 indicate a potential turning point, but these figures remain well below replacement levels. The increases in marriage rates, especially in South Korea, are promising indicators that social attitudes are shifting positively. However, the long-term demographic outlook remains challenging, with projections showing significant population declines by 2072. Governments' efforts to boost fertility are likely to have limited impact unless sustained and complemented by broader economic and social reforms. The data underscores the urgency of addressing structural issues like economic insecurity and social support systems to stabilize populations.
How we got here
Both Japan and South Korea have experienced prolonged declines in birthrates, driven by economic pressures, social attitudes, and aging populations. Governments have implemented policies such as financial incentives, childcare support, and housing benefits to encourage childbirth. Recent data shows signs of stabilization and slight increases, possibly reflecting policy impacts and changing social attitudes.
Our analysis
The Japan Times reports that Japan's birthrate decline has slowed, with births increasing slightly in 2025, supported by government measures totaling ¥3.6 trillion annually. However, the decline remains significant, and the population is still shrinking. The article highlights that only Tokyo and Ishikawa recorded increases, and the total fertility rate remains below replacement level. Heesu Lee from The Japan Times notes that the expected number of children per woman increased to 0.8 in 2025, the highest since 2021, with a 6.8% rise in births. The government has expanded financial allowances and childcare support, which may be contributing to this trend. Reuters reports that South Korea's fertility rate rose to 0.80 in 2025, supported by an 8.1% increase in marriages and government policies aimed at reversing demographic decline. The country’s population is projected to shrink by nearly a third by 2072, with the government planning a five-year policy roadmap to address aging and workforce issues. The data suggests a positive social shift, but the fertility rate remains below the level needed for population stability. Contrasting perspectives include the cautious optimism from South Korea, where officials see signs of recovery, versus the persistent demographic challenges highlighted by Japan's continued population decline despite slight improvements. Both articles emphasize that while policy measures are showing some effect, the long-term outlook remains uncertain, and structural reforms are necessary to prevent further population decline.
