“Life expectancy at birth increased between 1990 and 2015 by 4.0 years for men and 4.5 years for women, reaching 80.5 years and 86.8 years, respectively (Nomura S et al., 2017). However, regional disparities have widened during the same period. The gap between the highest and lowest life expectancy among prefectures increased from 2.5 years in 1990 to 3.1 years in 2015.
“Healthy life expectancy at birth, the average number of years that a newborn can expect to live in full health, rose from 70.4 years in 1990 to 73.9 years for both sexes in 2015. In 2015, healthy life expectancy was 71.5 years for men and 76.3 years for women. The gap between life expectancy at birth and healthy life expectancy at birth observed in 1990 has been static until 2015. All-cause age-standardized mortality rates for both sexes decreased by 29.0% between 1990 and 2015, falling from 584.1 deaths per 100 000 people in 1990 to 414.8 deaths per 100 000 people in 2015. Prefecture-level reductions in age-standardized mortality rates varied from 22.0% in Okinawa to 32.4% in Shiga between 1990 and 2015.
“There have been significant improvements in life expectancy over the past 35 years in all OECD countries, as shown in Table 1.4. According to OECD data, of the 12 high-income OECD countries, Japan has the highest life expectancy at 83.7 years in 2015. This longevity compared to other OECD countries has been sustained over time. Among other OECD countries, Italy (82.7 years) has the second longest life expectancy followed by France (82.4 years) and Korea (82.3 years). The lowest life expectancy among OECD countries was observed in Mexico (76.7 years). The contributing factors to the relatively long life expectancy in Japan may be attributable to a healthy lifestyle, diets and other risk factor profiles, sanitation and hygiene, universal and equitable health coverage and social determinants (Horiuchi S, 2011; Ikeda N et al., 2011).”
