In a Nutshell
The secret to Japan's low obesity rate lies in a unique combination of a healthy diet (unprocessed foods, fermentation), an active lifestyle integrated into daily life (tatami mats, walking), a deep connection with nature (forest bathing, onsens), and a life philosophy centered on well-being (wabi-sabi, ikigai). The kimono, traditional clothing, even plays a role in this harmony.
1. A Healthy and Balanced Diet: The Foundation of It All
The traditional Japanese diet is recognized worldwide for its benefits. It emphasizes fresh, unprocessed, and seasonal foods. Rice, fish, vegetables, soy (tofu, miso), and seaweed are staples. As Dr. Makoto Suzuki, a renowned Japanese cardiologist and author of "The Okinawa Program" (based on the diet of Okinawa, a region of Japan famous for its longevity), points out, "The Japanese diet, rich in antioxidants and low in saturated fat, is a key factor in cardiovascular health and the low rate of obesity." (Source: Suzuki, M., et al. The Okinawa Program. Clarkson Potter, 2001). Portions are generally small, and the Japanese have a habit of stopping eating before they are completely full ("hara hachi bu").
2. The Power of Fermented Foods: An Unexpected Ally
Fermented foods occupy an important place in Japanese cuisine. Miso, natto (fermented soybeans), tsukemono (pickled vegetables), and amazake (a fermented rice drink) are rich in probiotics, beneficial for intestinal flora and the immune system. Studies, such as the one published in the Journal of Physiological Anthropology in 2014, show that regular consumption of fermented foods can contribute to the reduction of inflammation and better weight management. (Source: Wastyk, H. C., et al. "Gut-microbiota-targeted diets modulate human immune status." Journal of Physiological Anthropology, vol. 33, no. 1, 2014, p. 21.)
3. An Active Lifestyle, Even at Rest: Tatami Mats and Daily Movement
Physical activity is integrated into the daily life of the Japanese. Many travel on foot or by bicycle, even in large cities. In addition, the use of tatami mats at home encourages an upright posture and engages the core muscles, even at rest. Sitting down and getting up from the floor frequently helps maintain flexibility and balance.
4. Nature at the Heart of Well-being: Forest Bathing and Onsens
The Japanese maintain a deep connection with nature. "Shinrin-yoku" (forest bathing), which involves walking in the forest mindfully, is a practice recognized for its relaxing and anti-stress benefits. Onsens (hot springs) are also very popular and offer moments of relaxation and regeneration. These practices help reduce stress, a known factor in weight gain. A study published in Environmental Health and Preventive Medicine in 2010 showed that forest bathing reduces cortisol levels (stress hormone) and improves immune function. (Source: Li, Q., et al. "Effect of forest bathing trips on human immune function." Environmental Health and Preventive Medicine, vol. 15, no. 1, 2010, pp. 1 9-17).
5. Wabi-Sabi and Ikigai: The Philosophy of Happiness and Longevity
Wabi-sabi, which values the beauty of imperfect and ephemeral things, and ikigai, which encourages finding one's purpose in life, contribute to a positive outlook on life and a reduction in stress. This philosophy promotes a balanced approach to food and well-being, far from restrictive diets and aesthetic pressures. According to Hector Garcia, author of the bestseller "Ikigai: The Japanese Secret to a Long and Happy Life," "Finding your ikigai is essential for a fulfilling life and better health." (Source: Garcia, H., & Miralles, F. Ikigai: The Japanese Secret to a Long and Happy Life. Penguin, 2017).
6. The Kimono: Clothing that Influences Posture and Digestion
Although less worn daily, the kimono is a traditional garment that promotes good posture and supports the lower back. The obi belt, wide and tight, can limit the expansion of the stomach during meals, thus contributing to a feeling of satiety more quickly. This tradition can be seen as yet another element contributing to moderation in eating.
FAQ

Q: Does genetics play a role in the low obesity rate in Japan?
A: Genetics may play a role, but environmental factors and lifestyle are considered to be the main contributors.
Conclusion
Japan's low obesity rate is the result of a synergy between a healthy diet rich in fermented foods, an active lifestyle integrated into daily life, a deep connection with nature, and a philosophy of life focused on well-being and balance. More than just a diet, it's a way of life that inspires and can guide us towards better health. So, what will you incorporate from these Japanese secrets into your daily life?
