The average life expectancy for Japanese men is 80.5 years of age, while for women, life expectancy was calculated at 86.83 years of age, Fuji TV reported Friday.
U.S. expectancy in 2011 was 78.7 years, which is slightly below the OECD average of 80.1. For U.S. men, the average life expectancy is 76, while it's 81 for U.S. women.

The U.S. life expectancy comes in just behind Slovenia, at 80.1 years, and Denmark, at 79.9 years.
