All I can say is, don't have children in Japan.

If you do, and you wish to maintain your kids for primary residence for whatever reasons upon separation, you will have no chance and you will lose the shirt off ya back.

A Japannese would never be "bettered" by a foreigner within Japanese courts.

I had a good feamle American friend in Japan who was being violated by her JP husband.

She knew the rules, she got out quick back to the US with her son.
