Experts in Japan are warning of a doomsday scenario in which the Japanese could face extinction, if the current birthrate stays.
A study claims the last child will be born in 3011 and then the Japanese would simply cease to exist.
Foxnews quoted calculations from academics at the city of Sendai that revealed there are now 16.6 million children under the age of 14 now in Japan.
And they say that number is shrinking at a disturbing rate of one every 100 seconds.
According to this number, the country will run out of children within a millennium.
Japan government projections also show birth rate will hit just 1.35 children per woman within 50 years, much the country's replacement rate.
The academics have now created a population clock to show Japan how close they are to doomsday.
"By indicating it in figures, I want people to think about the problem of the falling birthrate with a sense of urgency," Professor Hiroshi Yoshida, who led the research team, was quoted by ABC news telling the Japan Times newspaper.
Many have also asked why the shortage.
The report highlights two very important points. Japan is a very expensive country and education - school and college - can wipe out a middle - class family's savings.
Research also points at an interesting direction.
Japan has seen the rise of 'effeminate' men called 'Herbivores', who are either 'not interested' in sex or women don't find them 'masculine enough'.
Also, many Japanese have taken to 'virtual' friends with the country witnessing a boom in advanced 'replacements' - for affection.
