Japan has reached a remarkable milestone, with more than 100,000 people aged 100 or older now residing in the nation. The country’s centenarian population rose for the 56th consecutive year, reaching a record 107,677 this September, nearly 8,000 more than the previous year.
Scientists attribute Japan’s longevity to factors including a nutritious diet and access to high-quality medical care. Despite the demanding work culture in major cities, many people also find balance through ikigai, the practice of cultivating personal meaning and daily joy. Japan has one of the world’s highest life expectancies, averaging 84 years in 2024, compared with 79 in the US.
Of that 107,677 figure, Japanese women account for 88% of the total, or 94,298 people. What's more, Japan’s remarkable longevity also highlights a much broader demographic shift affecting countries globally.
Reaching the age of 65 is considered a milestone in many parts of the world, but a growing older population can also put pressure on social security, healthcare, and pension systems. As a result, many nations depend on a strong working-age population to support both older and younger generations.
Many industrialized and developed countries are facing declining birth rates alongside rapidly aging populations. Consequently, these demographic changes are creating significant challenges for economic productivity and long-term sustainability.
