Base registry

In order to promote digitalisation throughout the country, it is essential to develop digital infrastructure as social infrastructure. In Digital Agency, we are promoting the development and utilization of datasets that serve as the foundation of society as a base registry in order to promote information coordination among administrative organizations and the utilization of datasets including private sector. This will lead to the promotion of once-only administrative procedures (making it unnecessary to submit once and twice) and digital transformation in private sector.

What is the base registry?

A base registry * is a database consisting of data that is referenced in a large number of procedures across systems, such as addresses, locations, and names of corporations. The development of the base registry contributes to improving the convenience of citizens and the efficiency of administrative operations. The development of the base registry makes various procedures more convenient, such as eliminating the need to obtain documents such as certificates, eliminating the need to manually enter information, and eliminating the procedures themselves.
*In order to systematically and comprehensively develop and improve the Base Registry, Digital Agency submitted a bill to revise the Base Registry (a bill to partially revise the Basic Act on the Formation of a Digital Society Registry) to the 213th ordinary session of the Diet, and this bill was passed by the Diet on May 31, 2024.

On June 13, 2025, the Cabinet approved the " Public Basic Information Database Development and Improvement Project " provided for in the Digital Administration Promotion Act (Act on the Advancement of Government Administration Processes That Use Information and Communications Technology). In the future, we will develop, improve, and promote the use of the database based on the plan.
