After years of pressure from foreign governments and enormous efforts by "left-behind" parents to have access to children abducted to and from Japan after marital separation or divorce, the Japanese government became a party to the Hague Convention on the Civil Aspects of International Child Abduction in April.

That is, of course, good news. Now the issue becomes one of enforcement. And to that end, this column has serious doubts that the Japanese government will honor this treaty in good faith.

These doubts are based on precedent. After all, Japan famously ignores human-rights treaties. For example, nearly 20 years after ratifying the U.N. Convention on Racial Discrimination, and nearly 30 since acceding to the U.N. Convention on Discrimination against Women, Japan still has no law against racial discrimination, nor a statute guaranteeing workplace gender equality backed by enforceable criminal penalties.
