Japan has a fair amount of stigma attached to having your child watched by someone outside the family. People just don`t do it. Sure there is some informal "keeping an eye on" by neighbors and the like - but paying someone to watch your kids is pretty much unheard of.

Either family watches them, they go to a nursery/preschool, or... Well, that`s about it. Nannies and Au pairs are rare enough to be unknown.
