Japan has hit a remarkable milestone: nearly 100,000 people are now centenarians, living to celebrate their 100th birthdays. As of September 2025, there are 99,763 Japanese citizens aged 100 or older, according to the Ministry of Health, Labour and Welfare. This marks the 55th consecutive year of growth in the centenarian population, highlighting Japan’s ongoing commitment to health and wellbeing.
### A Closer Look at the Centenarians
Most centenarians in Japan are women, making up 88% of this age group. This trend aligns with global observations that women tend to live longer. Notable centenarians include Shigeko Kagawa, Japan’s oldest person at 114, who worked as an obstetrician until she was 86, and Kiyotaka Mizuno, 111, from Iwata. Their stories showcase longevity and active living.
### Celebrating Longevity
This announcement coincides with Elderly Day, a day dedicated to honoring senior citizens. Each year, centenarians receive gifts like silver cups and letters from the prime minister. In 2025, over 52,000 people were celebrated, highlighting Japan’s cultural respect for the elderly.
Historically, Japan’s centenarian numbers were much lower. Only 153 people were recognized as centenarians in 1963. This number grew to over 10,000 by 1998, and it keeps climbing. Increased access to healthcare, improved nutrition, and a focus on disease prevention are key factors in this growth.
### What’s Behind the Longevity?
Experts point to a combination of diet and lifestyle for Japan’s high life expectancy. Traditional Japanese diets are rich in fish, vegetables, and fermented foods, which contribute to lower obesity and chronic illnesses. Health initiatives have also played a significant role; Japan implemented effective measures to reduce salt and sugar consumption in the postwar years, leading to better overall health.
Physical activity is a staple of daily life. Many seniors engage in communal exercises, like the popular Radio Taiso, which has been around since 1928. This routine not only keeps them fit but fosters community connections as well.
Recent data shows that the global average life expectancy is now 73 years, but Japan leads with an impressive average of about 85 years. The World Health Organization reports that countries focusing on preventative care and healthier lifestyles often see similar trends in longevity.
### Challenges Ahead
Despite this success, Japan faces significant demographic challenges. A rapidly declining population is raising concerns. In 2024, Japan saw nearly one million more deaths than births. This decline can strain the healthcare system and pension programs, as an aging population may lead to fewer workers.
In conclusion, Japan’s journey to becoming a country with one of the highest numbers of centenarians is a mix of tradition, health care, and community spirit. While celebrating this achievement, it’s essential to address the challenges that come with an aging society.
