Japan Surpasses 100,000 Centenarians Amid Deepening Demographic and Labor Crises

Japan has officially surpassed a historic demographic milestone, recording more than 100,000 citizens aged 100 or older for the first time. According to official figures released by Japan’s Ministry of Health, Labour and Welfare, the total number of centenarians climbed to a record 107,677 this year. This represents an increase of 7,914 individuals from 2025 and marks the 56th consecutive annual rise in the country's centenarian population. Women make up nearly 88 percent of this demographic group.

While Health Minister Kenichiro Ueno expressed public satisfaction regarding the milestone, citing advances in medical technology alongside healthy lifestyles and diets, the record figures highlight a profound structural imbalance. Japan is currently confronting an accelerating demographic crisis characterized by a rapidly ageing citizenry and historic lows in fertility.

Japan maintains one of the oldest populations worldwide. Nearly three in every ten residents are aged 65 or older, a proportion that government projections indicate could approach 40 percent by the year 2070. The acute nature of this shift is underscored by generational comparisons: government data shows that more than 800,000 people in Japan were aged 95 or older last year, whereas only 700,000 babies were born during the same period.

Consequently, the nation's overall population is declining at a swift pace. Preliminary census figures indicate that population totals dropped in 45 out of Japan's 47 prefectures in 2025 compared to five years prior, with population growth recorded exclusively in Tokyo and Okinawa. Having peaked at approximately 128 million in 2008, Japan's population is projected by the National Institute of Population and Social Security Research to fall to 87 million by 2070—representing a roughly 30 percent contraction.

Researchers attribute Japan's extraordinary longevity to a multifaceted mix of diet, physical activity, and robust healthcare access. Traditional Japanese dietary patterns typically feature high consumption of fish, vegetables, and rice alongside low levels of saturated fats, helping keep obesity rates well below those seen in many Western countries. Furthermore, daily routines frequently incorporate walking, cycling, public transit use, and group exercise. Japan's universal health insurance system also provides broad, low-cost access to treatments and medicines compared to nations like the United States.

However, this longevity coincides with a severe fertility crisis. Japan's total fertility rate—the average number of children a woman is expected to have in her lifetime—dropped to a record low of 1.14 in 2025, falling far short of the roughly 2.1 rate required to maintain a stable population without immigration.

Social scientists and officials point to multiple factors behind the persistent decline in births. Fewer Japanese individuals are marrying, and those who do marry often do so later in life, reducing the window for family planning. Many younger adults express deep apprehension regarding insecure employment, stagnant wages, and demanding work hours. Additionally, women's increased participation in the workforce has not been matched by an equitable redistribution of household and childcare duties, making careers difficult to balance with parenthood.

Prime Minister Sanae Takaichi and other Japanese officials have repeatedly warned that population decline and falling birthrates threaten the country's foundational economic and social structures. Although the government has launched various countermeasures—including child allowances, subsidized childcare, and parental leave programs—these incentives have thus far failed to reverse the downward trend.

The economic consequences of this demographic shift are far-reaching. A shrinking working-age population results in fewer taxpayers funding social security and income taxes, even as expenditures for pensions, healthcare, and eldercare surge. This imbalance strains public finances and places heavy financial burdens on younger generations.

Severe labor shortages are already impacting critical industries, including construction, agriculture, transport, healthcare, and social care. Rural regions face particularly acute challenges as younger workers migrate to major urban centers, leaving behind ageing communities with diminishing public services.

While immigration offers a potential avenue to alleviate labor shortages, and the foreign population has risen moderately in recent years, foreign nationals still account for only about 3 percent of Japan's total population. Proposals to substantially expand migration remain politically sensitive and contentious.

Japan's demographic trajectory is part of a broader global shift. According to the World Health Organization, global life expectancy reached 73.3 years in 2024, an increase of 8.4 years since 1995, driven by socioeconomic and health developments. The number of people aged 60 or older is expected to grow from 1.1 billion in 2023 to 1.4 billion by 2030.

Nevertheless, this transition is significantly more advanced in East Asia and parts of Europe than elsewhere. United Nations World Population Prospects place Japan's median age at 49 in 2023, followed by Italy at 47.5, Portugal at 46.2, Greece at 45.7, and Germany at 45.1.
