Japan is a country where ancient traditions harmoniously blend with modern life. Its people enjoy one of the highest life expectancies in the world—over 84 years on average. But what truly stands out is not just how long they live, but how well they age—maintaining vitality, energy, and radiant health well into later years.
Their secret doesn’t lie in magic formulas or expensive treatments. Instead, it’s found in simple, balanced, and sustainable daily habits rooted in mindfulness and respect for the body.
Below are six Japanese practices that promote longevity and help preserve youthful skin and energy.
1. Eat Until You Are 80% Full

The Japanese follow a principle called “Hara Hachi Bu,” which means stopping eating when you’re about 80% full. This mindful approach prevents overeating, supports digestion, and triggers natural processes that slow cellular aging. Eating slowly and savoring smaller portions helps you better connect with your body’s signals of fullness and satisfaction.
2. The Power of Miso and Soups
Soups—especially miso soup—are a cornerstone of the Japanese diet. Made from fermented soybeans, miso is rich in probiotics, antioxidants, and essential nutrients that support gut health and strengthen the immune system. Starting a meal with a light soup helps control appetite, improves digestion, and warms the body from within.
3. Less Salt, Less Oil
In several Japanese regions, people consume less than one gram of salt per day and limit oil to about a teaspoon. This small change makes a major difference for cardiovascular health. Rather than relying on salt or fats for flavor, the Japanese enhance their meals with herbs, seaweed, and umami-rich ingredients that are both tasty and heart-friendly.
4. Walking as a Way of Life

While many cultures emphasize gyms and structured workouts, physical activity in Japan is seamlessly woven into daily life. People often walk to work, use public transportation, and enjoy leisurely strolls in parks. This consistent, low-impact movement improves circulation, strengthens the body, and promotes mental clarity and calm.
5. The Value of Tofu
Tofu is a staple in the Japanese diet, offering plant-based protein with few calories and numerous benefits. It contains isoflavones, compounds that help maintain firm, healthy skin and balance hormone levels. Regular tofu consumption has also been linked to a lower risk of heart disease and certain cancers.
6. Fermented Foods at Every Meal
From miso and natto to pickled vegetables and fermented fish, these foods are deeply ingrained in the Japanese diet. Rich in probiotics, they nurture the gut microbiome, boost immunity, and reduce inflammation—one of the main contributors to premature aging.
Practical Tips to Incorporate These Habits

- Include light soups and fermented foods in your daily meals.
- Replace salt and oil with natural herbs, seaweed, and seasonings.
