Year after year, Japan consistently ranks as one of the top countries for life expectancy. These top 10 facts about life expectancy in Japan is a reflection of economic developments that occurred since World War II.

Top 10 Facts About Life Expectancy in Japan

1. Japan ranks second in the world for life expectancy, with the average Japanese citizen living to 85.0 years. The life expectancy for the average female in Japan is 88.1 years and 81.9 years for males. There has been a fairly consistent difference in the life expectancy between women and men in Japan. Currently, women are expected to live around 6.2 years longer than men. Prior to 1990, the country had not even made the list of the top 100 countries with the highest life expectancies.
2. The fertility rate in 1955 for Japan was 3.0 live births per women, which has decreased to 1.4 in 2020. A decrease may appear worrisome but there is a clear correlation between fertility rates and wealth. Poorer nations tend to have high fertility rates which continues a cycle of poverty but intermediate levels of fertility tend to represent an economically stable, wealthy country.
3. Infant mortality and overall child mortality rates have greatly decreased since the 1950s. In 1950, the infant mortality rate was roughly 47 deaths per 1,000 births and the number of deaths for children under 5 was 72 per 1,000 births. As of 2020, the infant mortality rate and deaths for children under the age 5 is 1.6 and 2.2 per 1,000 births, respectively. These statistics display growth that has contributed to a higher life expectancy in Japan.
4. Diet and lifestyle are major contributors as well. Japanese people tend to enjoy well-balanced, nutritious meals that consist of vegetables, fruits, fish and high-grain based foods. This diet is low in saturated fats and includes mainly natural, unprocessed foods. In addition, the country has succeeded in promoting a healthy and active lifestyle. Even in their old age, many Japanese seniors continue to exercise regularly.
5. Rapid economic growth was seen in the country in the 1960s and the Japanese Government made great efforts to invest in the country’s healthcare system. In 1961 the country adopted universal health insurance for their citizens which included vaccination programs and medical treatments that greatly decreased both adult and child mortality rates.
6. Increased economic prosperity is a contributing factor. After World War II, Japan experienced an extremely rapid growth in its economy. Increased economic prosperity led to medical technology advancements, universal healthcare access, improved diets and lifestyles, decrease in disease and deaths, improvements in education and lower mortality rates. Economic prosperity and life expectancy rates are related, as seen in Japan.
7. A smaller poverty gap can also account for life expectancy in Japan. In the 1970s, Japan had a smaller income and wealth gap in the population compared to many other developed countries and it has been proven that a higher inequality in wealth correlates to higher mortality rates.
8. Successful health education and a well-established health culture is what Japan is known for. Majority of citizens engage in regular physician check-ups and receive vaccinations and immunizations. Furthermore, Japanese people are encouraged to reduce their salt intake and red meat consumption, advice the people take seriously.
9. Practice of good hygiene is another factor in explaining the high life expectancy in Japan. Common practices such as handwashing and cleanliness is normal in Japan but the country also has sufficient access to clean, safe water and sewage systems as well.
10. Decreased cerebrovascular diseases. Historically, Japan has always had low rates of ischemic heart disease and cancer compared to other developed, high GDP countries. However, Japan had one of the highest rates for cerebrovascular disease from the 1970s-1980s. Thanks to health developments, Japan has greatly decreased their rates of cerebrovascular diseases within the past 20 years.
