Japanese Women Lead Global Life Expectancy for 40 Years as Aging Pressures Grow

Four Decades at the Top, With a Growing Care Challenge

Japanese women recorded an average life expectancy of 87.13 years in 2024, keeping the world's highest position for the 40th consecutive year, according to Japan's Ministry of Health, Labour and Welfare. Japanese men had a life expectancy of 81.09 years, placing them sixth worldwide.

Japan's lead applies to countries that publish comparable data. The figures describe a country where people live exceptionally long lives, but where a growing share of the population also needs support through retirement, illness and old age.

In 2024, Japan's population was estimated at 123.89 million, with nearly 30% aged 65 or older, the highest proportion of elderly citizens in the world. Longer lives have brought more years for families and communities to spend together. They have also increased demands on pensions, healthcare and services for older people as the workforce shrinks.

Healthy life expectancy gives another view of that achievement. In 2022, Japanese women could expect 75.45 years in good health and men 72.57 years. Alongside the headline lifespan figures, those numbers point to a substantial period when people may live with illness, disability or a need for assistance.

Japan's experience brings several issues together: the role of food and medical care, recovery after COVID-19, the pressures of population decline, and questions about records claiming exceptionally old ages. Understanding the country requires looking at both the length of people's lives and the conditions in which they spend their later years.

How Japan Compares With Other Wealthy Countries

Japanese women's life expectancy exceeds that of women in Switzerland, South Korea, Spain and France. Japanese men rank behind men in Sweden, Switzerland, Norway, Italy and Spain. The international comparisons place Japan near the top for both sexes, although its uninterrupted lead belongs to women.

The comparison accompanying the life expectancy figures shows how Japan has maintained its position while many developed countries have experienced periods of little improvement or declining life expectancy, often during the COVID-19 pandemic and related health crises.

The United States presents a contrast. Despite much higher healthcare spending per person, its life expectancy was given as 77.5 years in 2024, down from 79 years in 2019. The average for comparable wealthy countries was around 82.5 years, putting the United States about five years below that benchmark. American women also ranked lowest among their peers.

Japan's figures sit within a different demographic setting. Nearly three in every ten residents were at least 65 in 2024. The country therefore combines high life expectancy with an unusually large population of older people, making the provision of care a daily concern for families, employers and public services.

What Life Expectancy Measures

Life expectancy at birth estimates how long a newborn would live if the death rates measured at the time stayed unchanged throughout that person's life. In simple terms, statisticians take the current risk of dying at each age and use it to calculate an average lifespan.

A child's actual lifespan will depend on the conditions they encounter as they grow older. Medical treatments, living conditions and the risks of disease can all change. The published figure is a snapshot of the population's health at a particular time, rather than a personal forecast.

Japan's progress since the postwar period has been large. In 1947, life expectancy was 53.96 years for women and 50.06 years for men. Compared with 2024, that is an increase of 33.17 years for women and 31.03 years for men.

Those gains reflect decades of improvements in public health, nutrition and medical care. They also show why a small annual change in today's figures belongs within a much longer history of people surviving illnesses and living to ages that were less common in earlier generations.

Women in Japan now have a life expectancy 6.04 years longer than men, using the 2024 figures of 87.13 and 81.09 years. The difference matters for care planning because women, on average, have more years of later life to navigate.

Food, Healthcare and Everyday Activity

Japan's longevity has been linked to several features of daily life rather than a single habit. The traditional Japanese diet includes fish, vegetables, rice and fermented foods, with relatively little saturated fat. Smaller portions and fresh, seasonal ingredients are believed to help reduce obesity and chronic disease.

Japan's universal healthcare system gives nearly all citizens access to preventive care, screening and early treatment. Screening means checking for signs of illness before symptoms become obvious, giving people a chance to receive treatment earlier. Regular checkups and high vaccination rates are also part of the country's health picture.

Older people often remain physically active through walking, gardening and radio calisthenics, exercises performed to broadcast routines. These activities make movement part of ordinary life rather than something reserved for a gym or a sports club.

Family relationships, community connections and respect for elders are also cited as contributors. Social isolation, which is associated with a greater risk of early death, is described as less common in Japan than in many Western countries. Tobacco use has meanwhile fallen sharply since the 1970s, following public health campaigns and stricter regulations.

Research discussed in the countries and aging overview and the facts about Japan highlights healthy food, activity in later life and strong social networks as contributors to the country's longevity. Together with access to healthcare, they describe a combination of personal habits and public support.

Some of those practices, such as encouraging physical activity and healthier eating, can be adopted elsewhere. Others are closely connected to Japan's culture and history, making the experience more complicated than a list of foods or exercises to copy.

Cancer, Heart Disease and the Effects of COVID-19

Cancer remains a leading cause of death for men and women in Japan. The health ministry's calculations project that 25.59% of men born in 2024 would eventually die from cancer under the mortality conditions used in the estimates.

For women, the largest projected category is old age, at 20.75%, slightly above cancer at 19.06%. Cancer remains central to the disease burden even as more people survive to very advanced ages.

The ministry also calculated how life expectancy would change if cancer deaths were eliminated: it would rise by 3.11 years for men and 2.68 years for women. This is a statistical exercise showing how much cancer contributes to deaths across different ages.

Heart disease and stroke are other major causes of death. Deaths from heart illnesses have declined in recent years, helping life expectancy stabilize after disruption during the pandemic.

COVID-19 interrupted Japan's longer trend toward greater longevity. Life expectancy fell in 2021 and 2022, primarily because of increased deaths from the virus. In 2023, both men and women recorded their first rebound since the pandemic began as COVID-19 deaths declined.

Japan's recovery reflected its public health response and the adaptability of its healthcare system. The pandemic also affected healthy life expectancy, which declined slightly, particularly for men, amid wider disruption to chronic disease management and mental health.

The Milestones Behind the Latest Figures

Japan's current position developed over decades, with a recent interruption during COVID-19. The main dates show both the scale of the country's gains and the pressures that have emerged alongside them.

• 1947: Life expectancy stood at 53.96 years for women and 50.06 years for men.
• Since the 1970s: Tobacco use has declined sharply alongside public health campaigns and stricter regulations.
• 2010: Japan's population began a continuing decline. A government review also identified problems with records of people listed as over 100.
• 2021 and 2022: Life expectancy fell, primarily because of increased COVID-19 mortality.
• 2022: Healthy life expectancy was 75.45 years for women and 72.57 years for men.
• 2023: Life expectancy rebounded for both sexes as deaths from COVID-19 declined.
• 2024: Women's life expectancy reached 87.13 years and men's reached 81.09 years. Japan's population was estimated at 123.89 million.

Population projections point to further decline through 2030 and beyond. As the postwar baby boom generation moves into old age, the share of elderly residents is expected to keep rising, increasing the need for support even as the number of working people falls.

More Years of Life, More Demand for Support

Japan's shrinking population is driven by persistently low fertility and limited immigration. Fewer births mean fewer young people entering the workforce in later years, while longer lives mean more people drawing pensions and needing healthcare.

Employers and the government face the task of supporting a growing retired population with a smaller workforce. Pension systems, medical services and social care all feel that pressure. Families also face practical decisions about helping relatives whose needs may last for many years.

The government has introduced policies encouraging older adults to remain in employment longer. The retirement age has been raised, and companies are encouraged to provide flexible work options for older employees.

Work is only part of the response. Concerns remain about the sustainability of social support and the need for new approaches to elder care. Longer life becomes more manageable when people can stay healthy, remain socially connected and obtain help when their needs change.

Healthy Life Expectancy Shows a Different Gap

Healthy life expectancy measures the years people can expect to live in good health, free from significant disability or chronic illness. Japan's 2022 estimates were 75.45 years for women and 72.57 years for men, below the headline figures for total lifespan.

Placed beside the 2024 life expectancy figures, they give gaps of about 11.6 years for women and 8.5 years for men. The healthy life and total lifespan figures refer to different years, but together they illustrate the scale of the challenge: many people need support for a substantial period of their lives.

Women have the longer total lifespan, yet the gap between total and healthy life expectancy is also larger for them. For care services, that means planning for years when a person may need help with illness or disability, rather than concentrating only on survival.

Japan's efforts to narrow the gap include promoting exercise, healthy eating and social engagement among older people. The aim is to help residents retain independence and good health for more of their lives.

Shizuoka Prefecture has the longest healthy life expectancy for both men and women. That regional difference shows that national averages contain variations within Japan itself, with some places recording more healthy years than others.

Extreme Age Records Face Scrutiny

Japan is widely associated with centenarians, people aged 100 or older. In 2024, the country reportedly had 2.31 million people over 90. Okinawa has also been promoted as a Blue Zone, a place where exceptional longevity is linked to food, daily activity and social connections.

Saul Newman, a researcher at University College London, has challenged the reliability of many records concerning centenarians and supercentenarians, people older than 110. He argues that clerical errors, pension fraud and poor record keeping can produce false claims of extreme age.

A Japanese government review in 2010 found that 82% of citizens reported to be over 100 had already died. Similar problems have been identified in other places promoted as Blue Zones.

Newman, who received the Ig Nobel Prize in Demography for his work, described the economic consequences of inaccurate longevity records:

The question of true human longevity is obscured by fraud, error, and wishful thinking. Longevity data are used for projections that affect pension rates, hospital planning, and insurance premiums, so faulty data can have major economic consequences.

Age records affect decisions about how much money pension systems need, how many hospital places to plan and how insurers calculate premiums. Accurate records therefore matter to public budgets and services as well as to claims about the oldest individuals.

Japan's broad pattern of long life remains part of its national health picture. The debate over exceptional ages brings a further task: maintaining reliable records while assessing claims about particular people and the supposed secrets of Blue Zones.

What Other Aging Societies Can Learn

Japan combines access to healthcare with dietary habits, physical activity and social connections associated with long life. Its experience offers other countries practical areas to work on, including preventive care, healthier eating and opportunities for older people to stay active.

Japan also shows the demands that accompany longevity when births remain low and the population shrinks. Extending life requires sustained attention to pensions, care services, employment and the years people spend living with illness.

Healthy aging and social inclusion can help make longer lives a source of national strength. Reliable records are equally necessary for planning services and understanding extreme longevity. Japan's achievement is therefore both a health success and an ongoing responsibility to support people throughout their later years.
