A twenty-something year old Kagawa woman who had in-vitro fertilization found out mid-pregnancy that the hospital had injected her with the wrong egg–i.e. someone else’s baby. Apparently, the hospital accidentally used a left-over egg from a previous operation, found out later, and told her. She had an abortion and sued the Kagawa government, which administers the hospital, for 20 million yen. IVF is pretty common in Japan, but adoption, surrogate births, and most other ways in which you may bear someone else’s kid are not so accepted. Abortion, on the other hand, was once (not sure if it still is) the number two method of birth control.
