Divorced couples in Japan are now allowed to share custody of their children, after a landmark revision to Japan's Civil Code took effect on Wednesday.

Before the amendment was approved by parliament in 2024, Japan was the only G7 country that did not recognise the legal concept of joint custody.

Custody was typically granted to one parent - in most cases the mother - who had power to cut off the other parent's access to their children.

Domestic and international criticism has been mounting against the sole custody system in Japan, which critics say led many divorcees to become estranged from their children after losing custody of them.

Previously, divorcing couples in Japan were free to decide custody and visitation arrangements. But if they went to court over it, custody would only be awarded to one parent.
