Interesting. Yeah... what ii see most couple usually had 2-3 child the most. cuz living expenses there is not cheap. They dont have big house like western or asian developing countries do. I dont know if they have the similar like China's 'One-child policy' case, but prolly it's already in their mindset & knew they will not survive themselves if thay had many children.

Then if the mother is working, or single parent raising the child...the child is mostly put in Day-Care school until their parent finishd their work. It's not free...if not mistaken, 3,000en per day. Not sure about other prefectures or main city.

That's just my opinions & what ii experienced. Not sure about Orphanage.
