Japanese women enjoy the highest life expectancy of females across the world, new statistics show.
World Health Organization (WHO) research found that girls born in Japan are likely to live until the age of 86 years on average.
In 2000, when the WHO last published these statistics, Japanese women were expected to live until the age of 85 years.
The latest figures show male Japanese babies' average life expectancy at birth to be 79 years, up from 78 years expected in 2000. Men born in San Marino enjoy the best prospects of a long life.
Across both genders, the Japanese population typically reach the age of 83 years, up from 81 nine years ago.
Diet and education are two of the factors contributing to the longevity of the Japanese population, some experts have suggested.

Metropolitan Institute of Gerontology told the Guardian that there is no illiteracy among Japan's people.
"They are very sensitive about information on health problems, so I would say education is one of the important factors," the expert added.
