Japan reforms custody law to allow shared parenting after divorce

Japan has introduced a landmark reform to its family law system, allowing divorced parents to share custody of their children for the first time, marking a major shift in a system that previously granted control to only one parent. The legal revision, which came into effect this week, enables couples to choose between joint or sole custody after divorce. It represents the first major change to Japan’s child custody laws in decades. Before the reform, custody was typically awarded to one parent most often the mother who then had the authority to make all key decisions about the child’s life and could restrict or completely cut off access by the other parent. Critics of the old system said it often left non-custodial parents excluded from their children’s lives, with some describing it as creating “left-behind” parents who had little or no contact following divorce. Under the new rules, parents are encouraged to cooperate in raising their children and share responsibilities, including decisions about education, healthcare and living arrangements. If parents cannot agree, family courts will intervene to determine custody arrangements in the child’s best interests.

Supporters say the change brings Japan in line with other developed nations where joint custody is more common and helps ensure both parents remain involved in a child’s upbringing. However, the reform has also sparked concern. Some critics warn that shared custody arrangements could expose children or former partners to continued abuse in cases involving domestic violence, while others fear the courts may face increased pressure handling disputes. The change follows years of debate and campaigning by parents’ groups and international observers, particularly in cases involving cross-border custody disputes. The reform is expected to affect hundreds of thousands of families in Japan, as attitudes toward parenting and divorce continue to evolve.
