Have you ever wondered why some people live longer than others? While genetics play a role, where you live can have a significant impact on how long you live. So, which country has the highest life expectancy? The answer might surprise you.
Which Country Has the Highest Life Expectancy?
The country with the highest life expectancy in the world is Japan, with an average life expectancy of 84.8 years. This means that, on average, people in Japan live longer than those in any other country.

So, what is the secret to Japan’s longevity? Let us dive deeper.
What is Life Expectancy?
Before we explore why Japan tops the list, let us define what life expectancy means. Life expectancy is the average number of years a person is expected to live based on current health and living conditions. It is a key indicator of a country’s overall well-being and reflects factors like healthcare access, diet, and lifestyle.
Life expectancy can vary significantly between countries and even within regions of the same country. For example, while Japan enjoys an average life expectancy of 84.8 years, other countries may have much lower averages due to challenges like poverty, disease, and inadequate healthcare.

Japan’s remarkable life expectancy is not an accident—it’s the result of a combination of factors that promote health and longevity. Here is what sets Japan apart:
