Japan has 99,763 people aged 100 or older!

Japan just hit a number nobody in human history has ever hit before. As of September 1, 2025, Japan has 99,763 people aged 100 or older — a new national record for the 55th year in a row. To put that in perspective: in 1963, there were only 153 centenarians in the entire country. That's gone from 153 to nearly 100,000 in six decades. The oldest person in Japan right now? 114-year-old Shigeko Kagawa — a doctor who was still delivering babies past the age of 80. Her secret? "Walking extensively during house calls built strong legs, which are the source of my current vitality." She still reads the newspaper and does calligraphy every day. And here's the detail that stops you cold: 88% of Japan's centenarians are women. Scientists point to the usual suspects — a diet built around fish, vegetables, soy and green tea, lower consumption of red meat and sugar, strong community bonds, purposeful daily routines, and one of the world's best healthcare systems. But here's where it gets complicated. Japan's Prime Minister has called the country's demographic situation a "quiet emergency." The population of Japanese nationals fell by over 900,000 people in 2024 alone. More elderly people, fewer workers to support them, soaring medical costs — and a birth rate that shows no sign of recovering. The same country that figured out how to live the longest is struggling to survive as a society. Nearly 100,000 people over 100. And not enough young people coming up behind them. Two records. One country. A fascinating, uncomfortable question about what longevity actually costs. 🇯🇵
