Japan Legalises Joint Custody for Divorced Parents

Japan has revised its civil code to allow divorced couples to seek joint custody of their children, ending its status as the only G7 nation without this option. Previously, only one parent (usually the mother) could have custody.

The change is significant for children's wellbeing. Research showed that one in three Japanese children with divorced parents lost contact with the non-custodial parent entirely—a situation linked to psychological harm. The reform prioritizes maintaining relationships with both parents where possible.

Japan's legal system has historically emphasized clean breaks in divorce, viewing ongoing parental contact as disruptive. The shift reflects evolving understanding of child development and the importance of both parental figures.
