Why Indians Live 13 Years Less Than the Japanese

Living longer is something many wish for. Yet, a striking difference exists between India and Japan, with nearly a decade or more of life expectancy. While Japanese citizens typically live to around 85 years, Indians are expected to live about 72 years on average. This gap forces a closer look at not only health care or income, but how societies and individuals organize daily life, from diet to environment, and from work to rest.


The everyday choices we make, what we eat, how we move, and how we rest, shape our long-term health more than we realize. In countries like Japan, these everyday choices tend to support health. In India, they often do the opposite, and over time, the difference adds up.

• Balanced Diet: Traditional Japanese meals emphasize balance. It consists of fish, fermented vegetables, rice in modest portions, and minimal processed sugar or fat. In contrast, many Indian diets lean heavily on refined carbs, deep-fried snacks, and high salt intake, especially in urban and fast-paced lifestyles.
• Movement is medicine: In Japan, walking, cycling, and public transport are part of daily life. In India, long commutes, desk jobs, and limited pedestrian infrastructure often mean less movement and more sitting.
• Healthy Sleep Routine: Early rising, consistent sleep schedules, and mindful eating habits (like hara hachi bu, or eating until 80% full) are common in Japan. In India, late dinners, irregular sleep, and screen-heavy evenings disrupt metabolic recovery.
• The result? Over time, these patterns increase the risk of lifestyle diseases, heart disease, diabetes, and high blood pressure, which silently subtract years from life. Chronic inflammation, poor gut health, and stress-related hormonal imbalances become long-term burdens when not addressed early.

In short, when these small, daily habits tilt toward imbalance, lifespan does too.

Japan has a strong healthcare system and widespread preventive health checks, where routine health screenings are widely accessible and culturally normalized. From school-age checkups to workplace health audits, early detection is built into the system. This means conditions like hypertension, diabetes, and certain cancers are often caught before they escalate. In India, even though progress has been made, access to regular health checks, timely treatment, and strong public health systems is still uneven. Rural areas or marginalized communities often miss early detection or quality care. This means conditions that could have been managed earlier turn severe. The result: more years lost to avoidable disease.


How work and daily rhythm are set also matters. Japanese society may have its work stresses, but routines often include good infrastructure for transport, and public spaces where movement is natural. In India, long commuting hours, heavy workloads, crowded cities, and air or water pollution add unseen tolls on the body. Moreover, social support and community bonds in Japan often serve as buffers for stress. In India, rapid urbanization and changing family structures mean fewer such buffers for many. All this builds up and drains years.


Life expectancy isn’t just shaped in old age; it’s rooted in the earliest years. From nutrition and clean water to vaccines and safe environments, the first decade of life lays the foundation for how long and how well we live. In Japan, decades of investment in early childhood health, routine screenings, clean infrastructure, and universal immunization have created a strong baseline for longevity.
In India, while progress is visible, gaps remain. Access to clean air, safe walking paths, and early health services still varies widely across regions and income groups. Malnutrition, poor sanitation, and limited preventive care in childhood can trigger long-term health issues that are harder to reverse later.

• Early disadvantage often leads to chronic conditions in adulthood.
• Environmental exposure, like air pollution or unsafe water, can silently impact organ development.
• Preventive care in infancy is still uneven, especially in rural and underserved areas.
• Catch-up health is possible, but harder and costlier when the foundation is weak.

In short, the longer a child grows up without access to basic health and safety, the more years they risk losing later. That’s one reason the life gap between India and Japan still persists.

Lifespan isn’t just a mere number. It’s an indication of how healthy one is, and so blaming it on genetics isn’t right, as a lot of other factors contribute towards it too. It’s shaped by everyday choices, access to healthcare, early detection, and how we handle stress, food, and social support.
Comparing the Indian lifespan to that of Japan isn’t just about data and figures; it is about understanding how infusing simple, small, daily, healthy steps in one’s life can actually extend the lifespan. And if India invests in early health education, routine screenings, and lifestyle awareness, then we can begin to close the gap, too.
After all, living longer isn’t just about adding years; it’s about adding quality to every stage of life.
