Why is Japan's population declining?

Question:

Answer:

Several factors.
First of all is the baby boom generation after WW2 saw large families (3-8 children per family), families living together and more of an agricultural society. But the number of children per family sharply declined from th 70s onward as Japan became more industrialised, the economy started picking up and people started moving to cities. Cities were crowded, homes were built much smaller and families became nuclear (separated from relatives) and society started becoming more competitive.
During the rising Japanese economy, Husband worked 80 plus hours a week and were never home with their families. Even spouses started having to live separately due to school and work responsibilitys. The costs of just supporting a family and putting kids through school is astounding, where many family have to shell out extra costs to put their kids in after school classes, private schools and vacation classes just to help them keep up with the competition. Housewives started feeling the stress of raising children without fathers or relatives to help with care and started having fewer children. Eventually many Japanese women stopped getting married and having children altogether and started working. Japanese men, likewise have given up on getting married and have made work and study their main priority in life. Fertility and sex drive has also decreased signficantly among men and women also due to environmental factors.

I live in Japan, am married to a Japanese and am the mother of 2 children. Nowadays Japan is desprately trying to get families to have more children. Lots of money is being put into child care and families (especially Mothers) with children are getting more and more support. Companies are even giving married men "time off" in hopes they will get busy with the conception process and there are huge tax incentives for having more and more kids. But raising children in Japan still remains difficult and extremely tough if you do not have outside help.

This is why the population is declining. I know, kinda complicated, but I think it is happening in many industrialised countries.
