Japanese researchers on Friday unveiled a population clock that showed the nation’s people could theoretically become extinct in 1,000 years because of declining birth rates.
Academics in the northern city of Sendai said that Japan’s population of children aged up to 14, which now stands at 16.6 million, is shrinking at the rate of one every 100 seconds.
Their extrapolations pointed to a Japan with no children left within a millennium.
Yoshida said he created the population clock to encourage “urgent” discussion of the issue.
Another study released earlier this year showed Japan’s population is expected to shrink to a third of its current 127.7 million over the next century.
Government projections show the birth rate will hit just 1.35 children per woman within 50 years, well below the replacement rate.
Meanwhile, life expectancy — already one of the highest in the world — is expected to rise from 86.39 years in 2010 to 90.93 years in 2060 for women and from 79.64 years to 84.19 years for men.
More than 20 per cent of Japan’s people are aged 65 or over, one of the highest proportions of elderly in the world.
Japan has very little immigration and any suggestion of opening the borders to young workers who could help plug the population gap provokes strong reactions among the public.
