"Pair Ikuji" Adds Child Support Simulation for New Joint Custody System to Support Accurate Parenting Plans

Mycat Inc. (Headquarters: Meguro-ku, Tokyo) is pleased to announce the addition of a child support calculation simulation feature to its AI-powered joint custody support platform "Pair Ikuji" (https://pear-ikuji.com), corresponding to the joint custody system scheduled to take effect in April 2026. Japan's New Joint Custody System Starts April 2026 According to the Ministry of Justice, the amended Civil Code will take effect in April 2026, allowing parents to choose "joint custody" to exercise parental rights together even after divorce. Along with this, a "statutory child support" system will be introduced to guarantee the child's livelihood even when no support agreement exists, set at 20,000 JPY per month per child. Changes in Child Support Calculation under the New System Traditional child support calculations were generally based on the Family Court's "Child Support Calculation Table," which estimates amounts based on both parents' income and the child's age/number. With the implementation of the joint custody system, the following factors will be newly considered: ・Expense Sharing in Joint Custody: When both parents are involved in raising the child as custodians, the concept of cost sharing differs from traditional methods. ・Relationship with Statutory Child Support: While statutory child support (20,000 JPY/month) applies if no agreement exists, the amount based on the calculation table serves as the guideline if it exceeds the statutory amount. ・Expenses for Visitation/Exchange: Under joint custody, the frequency of visitation may increase, and burdens such as transportation costs need to be included in the parenting plan. Overview of the New Feature The child support simulation feature added to "Pair Ikuji" allows users to calculate estimated child support under the new joint custody system by entering the following information: ・Annual income of both parents (supporting both salaried and self-employed) ・Age and number of children ・Type of custody (joint custody or sole custody) ・Estimated frequency of visitation/exchange The simulation results display a comparison between the guideline amount based on the calculation table and the statutory child support, which can be utilized for creating parenting plans. Preparing for the New System For those considering child support arrangements or reviewing parenting plans ahead of the joint custody system's implementation, please utilize the simulation feature of "Pair Ikuji." *This service does not constitute legal advice.
