Japan's Centenarian Population Reaches Record High Amidst Deepening Demographic Crisis

Japan's centenarian population has reached a record high of 107,677, marking a significant milestone amidst the country's accelerating demographic crisis. According to the Ministry of Health, Labour and Welfare, this represents an increase of 7,914 from the previous year and the 56th consecutive annual rise. Women account for nearly 88 percent of this group.

Highlights

• Japan's population of individuals aged 100 and over has exceeded 100,000 for the first time, reaching 107,677.
• This marks the 56th consecutive annual increase, with 7,914 more centenarians than last year.
• Nearly 30 percent of Japan's population is aged 65 or older, a figure projected to approach 40 percent by 2070.
• Low birth rates and a shrinking workforce are intensifying pressure on pension, healthcare, and social care costs, impacting public finances.
• Government incentives to boost birth rates and immigration solutions have yet to reverse the long-term decline.

Details

Japan has one of the world's oldest populations, with almost 30 percent of its residents aged 65 or older. This proportion is expected to reach nearly 40 percent by 2070. Last year, over 800,000 people were aged 95 or above, while only 700,000 babies were born. This disparity contributes to a rapidly declining national population; it peaked at approximately 128 million in 2008 and is projected to fall to 87 million by 2070.

Researchers attribute Japan's longevity to a combination of factors, including a traditional diet rich in fish, vegetables, and rice, active lifestyles with widespread walking and cycling, and a universal health insurance system offering broad access to affordable treatment. However, this impressive longevity is coupled with one of the world's lowest birth rates. In 2025, the total fertility rate (average children per woman) dropped to a record low of 1.14, significantly below the 2.1 rate generally needed to maintain a stable population without immigration.

Why it matters

An aging population means fewer working-age individuals are supporting a growing number of retirees who often require higher levels of social care and medical intervention. This imbalance places substantial pressure on public finances and creates labor shortages across various industries, including construction, agriculture, transport, and healthcare. While the Japanese government has introduced child allowances, subsidized childcare, and parental leave programs, these incentives have not yet reversed the long-term decline in birth rates. Furthermore, proposals to significantly increase immigration remain politically contentious, leaving the country grappling with profound demographic challenges.
