Seems pretty messed up that this is even an issue, but two things in the article stand out in my mind as ridiculous...
(emphasis my own)
"Japan is an important partner and friend of the U.S., but on this issue, our points of view differ," the U.S. Embassy in Tokyo said Tuesday. "Our two nations approach divorce and child-rearing differently. Parental child abduction is not considered a crime in Japan."
Japanese family law follows a tradition of sole custody divorces. When a couple splits, one parent typically makes a complete and lifelong break from the children.
