Base registry

Last Updated:

In order to promote digitalization in the whole country, it is essential to develop digital infrastructure as a social infrastructure. In Digital Agency, in order to promote information cooperation between administrative agencies and data utilization including private sector, as a base registry, we are promoting the development and utilization of data-groups that are the foundation of society. This will lead to the promotion of once only (no need to submit something twice) administrative procedures and digital transformation of private sector.

What is the base registry?

A base registry is a database of addresses, locations, corporate names, and other data that can be referenced in numerous procedures across different systems. By developing and promoting the use of the database, the government aims to improve the convenience of citizens and the efficiency of administrative operations.

By establishing a base registry, various procedures can be made more convenient, such as eliminating the need to obtain documents such as certificates, eliminating the need for manual input, or eliminating the procedure itself.

*The official name of the legal base registry is defined as the "Public Basic Information Database." In order to develop and improve the legal base registry in a planned and comprehensive manner, Digital Agency submitted an amendment bill (a bill to partially amend Basic Act on the Formation of a Digital Society, etc.) to the 213th ordinary session of the Diet, which was passed on May 31, 2024.
* On June 13, 2025, the "Act on the Advancement of Government Administration Processes That Use Information and Communications Technology Public Basic Information Database Development and Improvement Plan " stipulated in the Digital Government Promotion Act () was approved by the Cabinet. In the future, we will develop, improve, and promote the use based on the plan.
