In a world where life expectancy continues to climb, Japan stands out as a beacon of longevity. As of September 1, the country’s population of individuals aged 100 and above has surged past 99,000, reaching a staggering 99,763 people. This marks a record high for the 55th consecutive year, with an increase of 4,644 from the previous year, according to data from the Ministry of Health, Labour and Welfare. It’s a testament to Japan’s remarkable progress in healthcare, lifestyle habits, and societal support for the elderly. But what does it take to reach such an impressive milestone? We dive into the stats, hear from one of the nation’s oldest residents, and explore the broader implications for anyone aspiring to a longer, healthier life.
The Rising Tide of Centenarians in Japan

Japan’s centenarian population has exploded since records began in 1963, when there were just 153 people aged 100 or older. Today, that number has multiplied by over 650 times, reflecting profound shifts in public health and demographics. Women dominate this group, making up more than 80% with 87,784 individuals. This gender disparity isn’t unique to Japan—globally, women tend to outlive men due to a mix of biological factors, like stronger immune systems, and lifestyle differences, such as lower rates of smoking and risky behaviors.
Leading the pack is Shizuko Kagawa from Nara Prefecture, the oldest woman at 114 years old. On the men’s side, Kiyotaka Mizuno from Shizuoka Prefecture holds the title at 111. In a heartwarming interview last year, Mr. Mizuno humbly shrugged off questions about his longevity secret, saying, “I have no idea.” But this year, he opened up a bit more, sharing wisdom that’s as simple as it is profound: “The most important thing is not to take things to heart. Since I was young, I never worried about things.” In Japanese, he phrased it as avoiding “kuyokuyo,” a term that captures unnecessary fretting or dwelling on negatives.
Living with his family, Mr. Mizuno maintains a routine that’s enviably straightforward. He rises at 6:30 a.m., enjoys three balanced meals without being picky about food, and indulges in hobbies like listening to sumo wrestling matches and sports broadcasts. It’s a lifestyle that echoes the harmony and moderation deeply rooted in Japanese culture, where concepts like “ikigai” (a sense of purpose) and “hara hachi bu” (eating until 80% full) are everyday practices.
Why Japan Leads the World in Longevity
Japan’s status as the country with the highest life expectancy—around 84 years on average—didn’t happen by accident. Several factors contribute to this centenarian surge, making it a model for aging societies worldwide. First, the nation’s universal healthcare system ensures accessible, high-quality medical care for all ages. Preventive screenings, early interventions, and advanced treatments for age-related conditions like heart disease and dementia play a huge role.
Diet is another cornerstone. The traditional Japanese diet emphasizes fresh fish, vegetables, tofu, and fermented foods like miso and natto, which are rich in nutrients and low in processed sugars and fats. Regions like Okinawa, often called a “Blue Zone” for its concentration of long-lived residents, highlight the benefits of plant-based eating and moderate calorie intake. Studies from organizations like the World Health Organization link these habits to reduced risks of chronic diseases.
Social and cultural elements can’t be overlooked. Japan’s emphasis on community and family ties provides emotional support, combating loneliness—a silent killer in many modern societies. Elders are respected and integrated into daily life, fostering mental well-being. Physical activity is woven into routines, from walking to work (even in old age) to participating in local festivals. And let’s not forget the role of technology: innovations like robotic companions and smart home devices help seniors maintain independence.
Yet, this longevity boom brings challenges. Japan’s aging population strains pension systems and healthcare resources, prompting discussions on sustainable policies. For an international audience, it’s a reminder that while genetics play a part (about 20-30% according to research), lifestyle choices account for the rest. Adopting Japanese-inspired habits could add years to your life, no matter where you are.
Universal Lessons from Japanese Longevity
Mr. Mizuno’s advice—not sweating the small stuff—aligns with global research on stress management. Chronic stress accelerates aging by increasing inflammation and cortisol levels, so practices like mindfulness, meditation, or even a daily walk can make a difference. Combine that with balanced nutrition: aim for colorful plates full of antioxidants from berries, greens, and nuts. Regular exercise, even gentle forms like tai chi or yoga, keeps the body resilient.
Sleep is non-negotiable—aim for 7-9 hours nightly to repair cells and boost immunity. And nurture relationships; strong social networks are linked to longer lifespans in studies from Harvard’s Grant Study. For those in bustling cities far from Japan’s serene countryside, small changes like joining a community group or cooking a simple stir-fry can bridge the gap.
Globally, Japan isn’t alone. Countries like Italy and Singapore also boast high centenarian rates, often due to similar Mediterranean or Asian diets. In contrast, nations with higher obesity rates, like the U.S., lag behind. But the good news? Longevity isn’t exclusive; with awareness and action, anyone can tilt the odds in their favor.
