One interesting figure has come out of the diaper manufacturer Unicharm.It announced last week for the first time ever sales of its adult diapers were larger than those for babies.
The question everybody asks is why is there a lack of children?
The answer seems to lie in several reasons. One reason is the cost. Japan is an extremely expensive country and getting a child through college can wipe out a family's finances.
Another argument is that there are more effeminate men now called "Herbivores" there who are either not interested in sex or women don't find masculine enough.
Then some suggest many young Japanese people prefer "virtual" friends with a robot or on the internet, while others suggest their fascination with comics rather than relationships is the cause for a lack of babies.
Despite concerns about the lack of babies, the country is still a very crowded place.
