Japanese men trailed with a life expectancy of 78.64 years, which placed them second for longevity after Icelandic men, who live an average of 78.8 years.
The government attributes Japanese longevity to a range of factors, including a healthy diet and improving medical care, a spokeswoman for the Health Ministry said.
The Japanese diet tends to be rich in vegetables and fish products and relatively low in animal fats.

The downside? Japan has an aging population. In fact, by 2030, it is predicted that Japan will be one of the world's most elderly societies.
