Japan Moves to Standardize Child Support: 'Statutory Alimony' Set at ¥20,000 per Month

September 14, 2025

In a significant step towards supporting single-parent households, Japan's Ministry of Justice has drafted an ordinance to establish a baseline "statutory alimony" payment, aiming to provide a safety net for children after divorce.

Setting a National Benchmark

The new system, part of broader civil code reforms introducing the concept of "child support," sets a standard monthly payment of ¥20,000 per child. This figure is intended as a minimum guideline for parents to negotiate from, ensuring a basic level of financial support is considered in all cases.

Flexibility and Real-World Application

The ordinance is designed to be flexible, allowing for adjustments based on the paying parent's income and the child's specific needs. The ¥20,000 figure is based on the estimated minimum cost of raising a child, derived from government statistics on household expenditures.

Addressing a Critical Gap

This move aims to tackle the widespread issue of non-payment and underpayment of child support, which disproportionately affects single-parent families, often pushing them into poverty. By establishing a clear, legally-recognized standard, the government hopes to facilitate smoother negotiations and reduce disputes, ultimately prioritizing the welfare of the child.

Looking Ahead

The ordinance is expected to be finalized and implemented in April 2025. While it does not mandate this amount in every case, it provides a crucial starting point for courts and families, marking a major shift in Japan's approach to post-divorce child welfare.
