Child-Rearing Support Registry

Last Updated:

The Child-Rearing Support Registry serves as a centralized database of support systems provided by national and local governments. Local governments can register information in the system which the application service providers utilize to deliver necessary information to families raising children in a timely manner through push notifications.
Currently, child-rearing families are required to gather child-rearing support program information from multiple channels, such as municipal websites, bulletins, and consultation desks.

This fragmented approach creates several challenges:

  • Families may lack awareness of available support systems, which can result in missed opportunities to receive child-rearing support
  • Families may be unable to consult others and have limited opportunities to access information
  • Families might miss application deadlines and lose access to child-rearing support

The Child-Rearing Support Registry aims to address these challenges by creating a system that delivers necessary information to families raising children.

About the Use of the Child-Rearing Support Registry

By leveraging the Child-Rearing Support Registry, local governments can provide information on child-rearing support systems, while application service providers can efficiently incorporate nationwide information into their services.
Through services integrated with the registry, relevant support program information can be provided to users via push notifications based on factors such as their place of residence and their child's age.
For a list of specific services and providers that have integrated with the Child-Rearing Support Registry, please refer to the website below.

Eligible Systems

The registry mainly covers child-rearing support systems for families with preschool-aged children, comprising 124 categories as of November 1, 2025.

This includes systems such as:

  • Support related to pregnancy and childbirth, such as health checkup for expectant mothers and the Childbirth Lump-Sum Allowances, and related services
  • Support for infants and young children, including health checkups, routine immunizations, and related services
  • Support for childcare and education, including day care centers, certified centers for early childhood education and care, temporary day-care services, and related services
  • Support for single-parent families, such as the Child-Rearing Allowance, and others
  • Other child-rearing support systems

For municipalities:

Municipalities are required to register information on child-rearing support programs in the Mynaportal Application Management System and make updates whenever a system is revised or discontinued.

For application service providers:

Application service providers may obtain Child-Rearing Support Registry information via the API for use in their services.
To implement the API, please apply through the Mynaportal API Specification Site (Japanese text).
