In brief
A 0.4% increase in first‑half 2026 births to Japanese nationals topped up to 320,458 – the first rise in 11 years and just below the 2025 record low of 671,236. The rise is attributed to a higher marriage rate in 2024 and 2025, offering early signs that Japan’s ageing, low‑birth trend may be easing. Nonetheless, experts note uncertainties about whether this uptick will be sustained.
In the first half of 2026, the number of babies born to Japanese nationals rose 0.4 percent year on year to 320,458, marking the first increase for the January‑June period in 11 years, government data showed on Wednesday.
The figure was almost on par with the pace recorded in 2025, when Japan’s annual number of births to Japanese nationals hit a record low of 671,236, according to statistics from the Ministry of Health, Labor and Welfare.
Officials attribute the modest uptick to a rise in marriages in 2024 and 2025, the Ministry’s data indicated. A higher number of couples tying the knot is believed to have led to more births in the two‑year span covered by the first‑half figures.
The National Institute of Population and Social Security Research projected in 2023 that annual births would fall below 680,000 by 2040. That projection already accounted for a steep decline, but the institute noted the downward trend has accelerated faster than expected.
While the 0.4 percent growth in H1 2026 is modest, it is significant enough to suggest that the long‑running pattern of falling birthrates may be beginning to slow. The Ministry’s most recent release treats the figure as an early signal that the ageing crisis could be easing.
The report compares the first‑half figures to the full 2025 year, noting the 671,236 babies in that year was the lowest for the only‑born category on record. That low underscores how considerable the recovery appears, even if it is still well below historic averages.
Because the study bases the birth increase on marriage trends, the government is monitoring the relationship between marriage patterns and birth outcomes closely. Policy analysts are looking at whether the marriage surge is sustainable and whether it will translate into a lasting rise in births.
The ministry’s release comes amid broader demographic concerns. Japan’s population is expected to age further and shrink in coming decades, making any sign of increased fertility a potentially game‑changing development.
Uncertainties remain about whether the 0.4 percent rise will hold beyond the first half of 2026, how enduring the marriage trend is, and whether the observed uptick will translate into a sustained slowdown of the long‑term decline projected by researchers.
