James Cook is relentless.

His four children were abducted to Japan from Minnesota by his Japanese wife in 2014. This was after Japan acceded to the Hague Convention on the Civil Aspects of International Child Abduction, so he might have had hope in the early days.

Using the baroque procedural regime the Diet passed for the sole purpose of implementing the Convention, he sought a return order for his children in the Osaka Family Court. The court granted a return order, but only for the younger two — twins, both 7 at the time — not the older pair, who were 12 (and also twins). In doing so, the judge demonstrated what many of us in this area already know: that family court judges — even those tasked to a Hague court — don't have a [bad word]-ing clue about children or what is good for them. Basic family law common sense says you don't separate siblings, particularly when they have already been deprived of one parent.
