How many children? Why? [View all]

In the US, usually, when a couple has many children (like 10+) it is connected to some kind of Christian religious imperative. That imperative makes no sense to me at all.

Here in Japan I have seen a few TV shows featuring couples who have 10-15 children.
In each case there is no religious imperative driving it --- they just seem to have lots of children.

The problem is, I never catch these shows at the proper time when the couple explains why they had so many children... I only know that in each case they are not religious. Another thing, it is very common for people to have just 1 kid here. (I can't get a good answer out of anyone here... everyone I mention it to either say they say they want 0 or 1 kids).

So, I come here.

How many children do people have?
How many were you shooting for?
Were you even shooting for a number?
Anybody wanted to have many children? Why?
