Why the number grows as you get older
Life expectancy at birth includes the risks of the first years of life. Someone who has reached 65 in Japan has already come through them, so the average expected age for 65-year-olds is 86.7, not 83.9. Men of 65 have 19.6 years ahead on average and women 23.6. Enter your own age in the calculator to see the number for people like you, or use the life expectancy clock to watch your time ahead tick.
