Child-Rearing Support Registry
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 app 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.
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.
How to Use
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 app providers:
App providers are required to submit applications through the Mynaportal API Specification Site (Japanese text) .
Progress of Initiatives
FY 2023
Pilot Project in Tokyo (FY2023-FY2024)
A pilot project for a Child-Rearing Support Registry was implemented in collaboration with the Tokyo Metropolitan Government and the national government.
- Database Development
- A database was created that compiled approximately 7,800 child-rearing support programs from 62 Tokyo municipalities and the Tokyo Metropolitan Government.
- Pilot Integration with Private-Sector Applications
- Six municipalities — Chiyoda, Toshima, Katsushika, Edogawa, Machida City and Mizuho Town — worked with 9 private child-rearing app providers to test the delivery of information via push notifications.
- Effectiveness Assessment
- The pilot confirms and assesses the feasibility of delivering effective information through child-rearing applications.
FY 2024
Data Preparation for Nationwide Launch
Since September 2024, surveys of child-rearing support programs have been conducted in designated cities and 150 municipalities.
The surveys include:
- Collecting information on each municipality’s child-rearing support programs
- Standardizing the data and registering it in a centralized database
- Verifying the data in coordination with each municipality
Expansion to other Municipalities (FY2024-FY2025)
Following the survey of designated cities, coverage is being progressively expanded to other municipalities to complete the nationwide dataset.
FY 2025
Launch of Operations in Designated Cities (schedule TBD)
- Disclosure of data for designated cities
- Launch of API connection by app providers
- Start providing information services for child-rearing families
Promote Nationwide Deployment (schedule TBD)
- Gradual release of data from additional municipalities
- Phased rollout to municipalities nationwide
- Expansion of collaboration with child-rearing app providers
FY 2026 and Beyond
Service Expansion (schedule TBD)
- Expansion of targeted programs will be considered
