Japan allows divorced couples to negotiate joint custody of children for first time

Japan has enacted a landmark revision to its Civil Code, allowing divorced couples to share custody of their children. The change ends a century-old sole custody system, aligning Japan with most other developed nations. Both supporters and critics weigh in on the implications for children's welfare and domestic abuse survivors.

Japan has introduced a landmark change to its child custody laws, allowing divorced couples to negotiate joint custody of their children for the first time. The revision to the Civil Code, which took effect Wednesday, ends more than a century of sole custody arrangements, a system that typically granted custody to one parent — in most cases the mother — and gave that parent power to cut off the other's access.

The amendment, approved by parliament in 2024, makes Japan the last G7 country to legally recognize joint custody. Under the new law, divorcing couples can decide whether to arrange joint or sole custody, and if they cannot agree, a family court will rule on the arrangement. Parents who divorced under the old system are also eligible to have their custody arrangement reviewed by a family court.

Coverage Comparison

Media coverage of the change has been broadly similar in its factual reporting, though different outlets have emphasized distinct aspects of the story. The BBC's report focuses on the legal and international context, noting that domestic and international criticism of the sole custody system contributed to the change. The Guardian's coverage highlights the human impact, including criticism that the previous system caused psychological harm to children and unfairly punished the parent who did not gain custody.

Both outlets report that Japan was the only G7 country that did not recognize joint custody before this change. The Guardian adds that about 200,000 children in Japan are affected by divorce every year, and that mothers were granted custody in 85% of cases under the previous system — a statistic not mentioned by the BBC.

Key Claims

Law change: Japan's Civil Code now permits joint custody of children after divorce, according to both BBC and The Guardian. The revision took effect on Wednesday.
Previous system: Before the amendment, Japan required divorcing couples to decide which parent would take sole custody. If they went to court, custody was awarded to only one parent, typically the mother.
2024 parliamentary vote: Pressure from critics led to a parliamentary vote in 2024 to change the law, as reported by both outlets.
Review for existing divorces: Parents who divorced under the old system can petition a family court to change their custody agreement, according to The Guardian.
Cooperation requirement: The revision calls on parents to respect each other's positions and cooperate "in the best interests of their child," as quoted by The Guardian.
Critics' concerns: Some critics say the previous system prevented non-custodial parents from playing a role in important decisions about their children's schooling, residence, and medical care. Others fear that joint arrangements could allow abusive former spouses to exploit greater access to their children, as reported by both outlets.
Child support mandate: The new law also mandates child support payments after divorce, allowing the parent living with the child to claim 20,000 yen (about £95 or $125) per month from their ex-spouse, per the BBC.
Parental abduction concerns: Allegations of parental abduction have come into the spotlight in recent years, with the BBC citing cases involving foreign parents with Japanese ex-spouses.

Perspectives

Supporters of the change

Proponents argue that the previous sole custody system was unfair and harmful. They believe it prevented non-custodial parents from being involved in significant decisions affecting their children's lives, such as education and healthcare. The change to allow joint custody brings Japan in line with most other countries and is seen as a step forward for children's welfare.

Critics and abuse survivors

Critics and domestic abuse survivors express concern that joint custody could give abusive former spouses greater access to their former partner and children, potentially continuing abuse. Some also worry that the revision places too much power in the hands of family courts, which will have to make decisions when parents cannot agree.

International observers

The international community, especially foreign parents who have been involved in custody disputes in Japan, has welcomed the change as a potential remedy for what they describe as parental abduction. The BBC notes that allegations of abduction by Japanese ex-spouses have drawn attention to the issue, though the new law does not specifically address abduction cases.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
