Japan Reaches Historic Milestone With Over 100,000 Centenarians Amid Deepening Demographic Crisis

Japan has officially surpassed 100,000 residents aged 100 or older, marking an unprecedented longevity milestone as the nation grapples with a rapidly accelerating demographic challenge. Data from Japan’s Ministry of Health, Labour and Welfare reveals that the total number of centenarians climbed to a record 107,677 this year, reflecting an increase of 7,914 individuals from 2025 and representing the 56th consecutive year of annual growth. Women make up nearly 88 percent of this demographic group.

Health Minister Kenichiro Ueno expressed enthusiasm about the milestone, noting his pleasure that so many individuals are maintaining long, healthy, and active lifestyles due to medical advancements, nutritious diets, and healthy habits. However, this celebration contrasts with a severe demographic imbalance characterized by a continuously growing elderly population alongside historically low birth rates, which puts mounting pressure on pensions, healthcare, and social care funding from a diminishing workforce.

According to government figures, Japan maintains one of the oldest populations globally, with approximately three out of every ten residents aged 65 or older—a proportion expected to approach 40 percent by 2070. Last year, the country recorded more than 800,000 individuals aged 95 or older while registering only 700,000 births. Preliminary census data indicates that 45 out of Japan’s 47 prefectures experienced population declines in 2025 compared to five years prior, with Tokyo and Okinawa serving as the sole exceptions. Projections from the National Institute of Population and Social Security Research suggest the overall population, which peaked near 128 million in 2008, will drop to 87 million by 2070.

Researchers attribute Japan's exceptional longevity to a mix of diet, physical activity, and healthcare accessibility. Traditional diets rich in fish, vegetables, and rice combined with low saturated fat and minimal obesity rates support these trends. Regular physical activity, such as walking, cycling, and group exercise, is common across age groups. Furthermore, Japan’s universal health insurance system offers affordable medical treatments and medications compared to nations like the United States.

Despite these achievements, low birth rates complicate the economic landscape. Japan’s total fertility rate dropped to a record low of 1.14 in 2025, well below the roughly 2.1 rate required to maintain a stable population without immigration. Prime Minister Sanae Takaichi and other officials have warned that the shrinking working-age population poses a severe threat to the nation's economic and social foundations, leading to labor shortages across construction, agriculture, transport, healthcare, and social care industries.

Globally, life expectancy continues to rise, with the World Health Organization reporting a global life expectancy of 73.3 years in 2024. Nevertheless, Japan's demographic transition remains exceptionally advanced, with a median age of 49 recorded in 2023, placing it ahead of nations like Italy, Portugal, Greece, and Germany in population ageing.
