The 10 Countries with the Highest Life Expectancy in the World

3. Japan

Life expectancy at birth (Years) – 83.91

With an obesity rate of just 3%, Japan holds quite the record on our rank of top 10 countries with the highest life expectancy. Their key staple diet consists of vegetables, fish, rice, and noodles, which is considered one of the healthiest in the world. Another important factor that gives Japan’s people an advantage in maintaining their good health is their reluctance to use transportation services, instead showing a preference for walking and bike riding.
