Japan’s population is declining more than ever after government data showed that births in 2025 fell to just over 671,000, the lowest level since records began in 1899.
The total dropped by nearly 15,000 compared with the previous year.
The fertility rate also fell to 1.14 children per woman, continuing a ten-year decline and remaining far below the 2.1 level needed to maintain a stable population.
Officials say fewer marriages are driving the trend. Annual marriages in Japan have fallen from about 800,000 in the early 2000s to around 500,000 today.
A researcher familiar with government demographic studies said, “The pace of decline is faster than expected. Earlier forecasts placed this level of fertility decades ahead.”
Despite the falling numbers, public attitudes toward marriage have not changed as sharply. Surveys indicate that about 80% of single adults in Japan still hope to marry, though many delay or abandon plans due to economic and social pressures.
Work, cost, and fewer opportunities to meet partners
Analysts point to several factors behind the decline. Young adults face unstable employment in some sectors, high living costs in major cities, and long working hours.
A sociologist in Tokyo said, “People still want families, but they struggle to find time, money, and stable conditions to start one.”
Social patterns have also shifted. Traditional ways of meeting partners through workplaces, schools, or friends have weakened. Remote work and privacy concerns have reduced daily social interaction, especially among young professionals.
As a result, matchmaking services and marriage agencies report growing demand, particularly among people seeking structured introductions rather than casual dating.
Government response
The government of Japan has introduced financial incentives, childcare expansion, and parental leave reforms to slow the decline. Local authorities have also expanded matchmaking programmes in some regions.
A government official involved in population policy said, “We are improving support for families, but reversing long-term social change takes time.”
Japan’s population now stands at roughly 123–124 million, down from its peak of about 128 million in 2008. Almost one in three residents is aged 65 or older, placing pressure on the workforce, pensions, and healthcare systems.
Experts warn that the gap between policy measures and demographic behaviour remains wide. Births continue to fall faster than projections, and marriage rates show no clear recovery.
