Ferra,

That's the thing about the village idea, your kids get inputs of many different values. They hear yours at home, and others with various villagers. And raising children to be fluently bilingual is rather simple if started at birth. For instance, say you marry a Japanese man who also speaks English. You speak to the children only in English, have your husband speak to them only in Japanese. Then speak to each other sometimes in Japenese, sometimes in English. That way the children will learn both equally and efficiently. Contrary to popular belief, this will not confuse the children at all if they are raised this way.

The most effective way to encourage your children to embrace a duel heritage is to embrace it yourself. If they see you participating in both the culture of your adopted and native lands, they're more likely to follow in your footsteps. That is, as long as you don't force it upon them. Forcing anything upon children in the realm of morals, values, and ideas is more likely to cause them to balk and go the exact opposite way. (Example: the stereotypical pastor's kid)

I'm not a parent myself, I only know what I've learned via my own experience as a child and what I've learned in psychology. But I think these points at least make a little sense. If you weren't looking for advice, my apologies. Couldn't help myself. XD
