Child Support & Co-parenting Support in Japan
Lumina Finch helps parents in Japan organize
child support agreements,
co-parenting arrangements,
and parenting rules in a simple way.
Effective from April 2026
Under the legal reforms taking effect in April 2026,
documenting child support arrangements in writing
has become increasingly important.
In April 2026, the post-divorce child support system in Japan was revised.
Previously, even when parents had agreed on child support between themselves, if payment was not actually made, a formal obligation document—such as a notarized deed or mediation record—was generally required for garnishment proceedings.
Under this reform, subject to certain conditions, a new framework now allows garnishment based on written child support arrangements created between parents.
In addition, a statutory child support system has been introduced for cases where no agreement exists.
However, living expenses, education costs, activities, and visitation arrangements vary greatly from family to family.
That is why it is more important than ever to discuss in advance and document child support, payment methods, and communication rules in writing.
Lumina Finch helps you organize these important arrangements through guided questions while supporting agreement document creation.
