Japan’s health ministry has recorded 107,677 residents aged 100 or older as of September 1, 2026, the first time the count has exceeded 100,000. Women account for 87.6 percent of centenarians, and the figure has risen for 56 consecutive years.
The milestone coincides with a record-low fertility rate of 1.14 births per woman and a health ministry budget request of 33.6872 trillion yen for pensions and medical care. The government is expanding foreign care worker visas nearly threefold to address a projected shortfall of 2.4 million elder care workers in 2026.
Japan’s pension system now supports roughly one-third of the population while the number of workers paying into it shrinks every year. That equation was already precarious. The health ministry’s announcement on September 15, 2026 that the country has surpassed 100,000 centenarians for the first time makes the arithmetic impossible to ignore.
The ministry’s budget request tells the story in yen: 33.6872 trillion for pensions and medical care in fiscal 2027, a 4.4 percent increase from the previous year. This allocation represents the bulk of the health ministry’s total request of 36.5803 trillion yen and is about a quarter of the government’s overall budget requests. That is a figure that will keep climbing as 54,294 more people turn 100 during the current fiscal year.
Prime Minister Sanae Takichi has called the combination of collapsing fertility and extreme longevity a “quiet emergency.” The phrase captures the nature of the crisis — it builds over decades, then arrives as a set of numbers that make the status quo impossible.
The fiscal basis of the quiet emergency
The 107,677 centenarians recorded on September 1 are not a surprise. The count has risen for 56 years. What is new is the convergence: the fertility rate hit a record-low 1.14 births per woman in 2025, and every prefecture except two saw population decline. The National Institute of Population and Social Security Research projects the population will fall from a 2008 peak of 128 million to 87 million by 2070, with nearly 40 percent aged 65 or older.
The institute frames this trajectory as an existential demographic crisis. Minister of Health, Labour and Welfare Kenichiro Ueno has highlighted that the growing elderly population poses significant challenges for maintaining the social security system. The numbers give that observation precision: about 40 million residents now draw public pensions, and the health ministry’s total budget request for fiscal 2027 reaches 36.5803 trillion yen.
The centenarian density itself reflects extreme longevity: 87.51 per 100,000 people. Japan recorded roughly 671,000 births and 1.59 million deaths in 2025. The gap between those figures is the structural deficit driving every fiscal projection and every visa expansion.
The Gerontology Research Group has noted that Japan is the first country to officially surpass 100,000 people aged 100 or older, making it a global test case for how pension, healthcare, and care-labour systems cope with extreme longevity. That test is now producing results that other aging economies are watching.

A welfare state built on a shrinking foundaton
Japan’s public pension and long-term care systems rely on a mix of payroll contributions and general revenue. As the working-age population contracts, each worker supports more retirees. The government’s policy response has been to expand foreign worker visas while keeping permanent setlement paths narrow. Specified Skilled Worker (Caregiving) visa holders can stay up to five years but cannot transition to permanent residency through that status alone.
The political logic is clear: import labour without importing citizens. The economic logic is less certain. The care sector needs 2.4 million workers in 2026, up from 2.1 million in 2024. The expanded visa ceiling of 135,000 total admissions for fiscal years 2024 through 2028 covers only a fraction of the gap, even at full take-up. Japan is testing whether selective immigration can stabilise a welfare state without the political cost of open borders.
Western governments watching from a distance have not announced specific policies in response, but Japan’s trajectory increasingly shapes OECD and G7 discussions on retirement ages and long-term care financing. Its decisions signal what other rich democracies may eventually confront: a point at which the math requires either higher taxes, lower benefits, or more workers from abroad.
Beyond the headline
The Bigger Picture
Japan’s centenarian surge marks the inversion of its population pyramid. Instead of a broad base of young taxpayers supporting a smaller elderly cohort, a growing share of national income now flows toward age-linked entitlements while the working-age pool shrinks. This forces Japan to test how far a rich democracy can stretch social insurance and selective migration before either benefits or fiscal orthodoxy have to give way.
The Response Gap
Policy moves lag behind demographic change. Budgets and visa caps inch upward, but the worker-to-retiree ratio deteriorates faster than these adjustments can compensate. Politically sensitive levers — large-scale immigration, major tax rises, or benefit reforms — remain only partially used. The gap lies between incremental measures and the scale of restructuring an economy with nearly 40 percent elderly citizens will ultimately require.
The Reach
Japan’s demographic decisions reverberate beyond its borders through global capital and care-labour markets. As Tokyo raises welfare spending and selectively opens doors to foreign caregivers, it influences how other aging economies think about importing labour versus exporting capital to fund pensions. For Western public pension systems and long-term care industries, Japan’s trajectory offers a concrete template for the trade-offs between domestic reform, international recruitment, and budgetary risk tolerance.
A test case with consequences beyond its borders
Japan’s demographic choices are now producing data that aging economies across the developed world are studying. Four groups in particular face decisions shaped by the numbers that arrived on September 15.
- Western expat in Japan with aging relatives
The expansion of foreign care visas and home-visit services creates new options for arranging care for family members in Japan. Check municipal care-need assessments and the availability of workers under Specifed Skilled Worker and Nursing Care statuses in your area. Be aware that higher social security spending makes future increases in health insurance premiums and pension contributions more likely for long-term residents paying into the national schemes.
- Western investor in Japanese public sector bonds
The 33.6872 trillion yen budget request signals a fiscal trajectory that will shape Japan’s long-term debt dynamics. Re-evaluate the risk profile of Japanese public sector bond holdings in light of the escalating social security allocation and the demographic decline that will sustain upward pressure on welfare spending for decades. The worker-to-retiree ratio is deteriorating faster than current policy adjustments can compensate.
- Aspiring foreign care worker for Japan
The 135,000-visa ceiling for FY2024–FY2028 opens a real entry point, but it is a competitive one. Research the updated visa requirements, skills tests, and language standards for the Specifed Skilled Worker (Caregiving) status at the Immigration Services Agency of Japan website before committing to training. Note that home-visit care is now permitted, expanding the types of work available, but permanent residency does not follow automatically from this visa track.
- Policy professional in an aging Western democracy
Japan’s strategy of pairing expanded foreign care-worker intake with restricted settlement paths and rising budget allocations is a live experiment in funding long-term care without structural immigration reform. Analyse how the 135,000 cap interacts with the 2.4 million worker gap to see where fiscal pressure will next concentrate. This is the template against which other aging economies will test their own trade-offs.
FAQ
Will my family be able to accompany me if I work as a care worker in Japan?
Specifed Skilled Worker (Caregiving) and other care-related statuses generally do not grant automatic long-term residence rights to spouses or children. Family accompaniment requires separate visa categories such as Dependent or Long-Term Resident, each with income and housing criteria. Check whether your specific status allows bringing family before committing to multi-year care roles.
How does private long-term care insurance work alongside Japan’s public system?
Japan’s long-term care insurance is mandatory for residents aged 40 and over, with benefits determined by care-need assessments and co-payments. Private policies typically supplement rather than replace the public scheme. Foreign residents should understand how municipal eligibility reviews, benefit levels, and co-pay tiers work when planning for home-visit or facility-based care.
Can I get permanent residency through a caregiving visa?
Specifed Skilled Worker (Caregiving) status does not lead directly to permanent residency and is capped at five years. Experience gained can sometimes support applications under other categories such as Nursing Care or Highly Skilled Professional, which have longer stays and clearer settlement routes. Track language requirements, qualification recognition, and employer sponsorship options when planning multi-stage migration through Japan’s care sector.
Explainer
- Specified Skilled Worker (Caregiving)
- A Japanese visa category created to address labour shortages in the elder care sector by allowing foreign workers to take caregiving jobs under defined skills and language standards. The status permits stays of up to five years but does not provide a direct path to permanent residency, and intake is capped by sector. The care-sector ceiling was reset to 135,000 admissions for fiscal years 2024 through 2028.
- Long-term care insurance
- Japan’s mandatory public insurance system covering care services for residents aged 40 and over, funded through premiums and general revenue. Benefits are determined by official care-need assessments and are subject to co-payments, typically 10 to 30 percent of service costs. The system is separate from national health insurance and is a major component of the social security spending driving the health ministry’s rising budget requests.
- Total fertility rate
- The average number of children a woman would have during her lifetime based on current birth rates, with 2.1 generally considered the level needed for a stable population without migration. Japan’s rate fell to 1.14 in 2025, a record low after years of decline and well below the replacement level, driving projections of a population drop from 128 million to 87 million by 2070.
- A Japanese government-affiliated research body that produces official population and social security projections used in policy planning. Its forecasts inform the health ministry’s budget requests and the government’s long-term fiscal assessments. The institute has framed Japan’s demographic trajectory as an existential crisis for the economy and welfare state.
