TOPPAN Corporation (Headquarters: Bunkyo-ku, Tokyo; Representative Director & President: Haruhiko Noguchi; hereinafter "TOPPAN"), a group company of TOPPAN Holdings, conducted a demonstration experiment from August 29, 2025, to March 31, 2026, as a project adopted by the Digital Agency, aimed at expanding the use of G-Biz ID in private services.
G-Biz ID is a corporate authentication system provided by the Digital Agency, allowing login to multiple administrative services with a single ID and password. It is widely used by many businesses for procedures between companies and government, such as subsidy applications and social insurance. Furthermore, in fiscal year 2027, its deployment to private services is scheduled to begin, making it available for inter-company procedures as well.
In this demonstration, a prototype system connected to the G-Biz ID platform was built to explore its potential for use in inter-company transactions. The experiment verified the improved convenience of applications and the usefulness of the system in trade procedures. As a result, it was estimated that the operational hours per case for service providers could be reduced by up to approximately 30%. Additionally, a hearing survey targeting three fields—trade, corporate SaaS, and financial services—confirmed a high demand for G-Biz ID utilization.
TOPPAN has consistently supported societal DX through promoting digital government and providing trust services (※1) such as identity verification and digital certificates. Moving forward, TOPPAN will leverage the results of this demonstration to further promote digitalization and reduce the operational burden in inter-company transactions.
This demonstration was conducted after being adopted by the Digital Agency's public solicitation for "FY2025 Call for Case Studies and Demonstration Connection Experiments for G-Biz ID Utilization in Private Services."
Future Vision and Image of Demonstration Items
■ Background of the Demonstration
In recent years, the online processing of administrative procedures has accelerated towards the realization of a digital society. G-Biz ID, provided by the Digital Agency, is an authentication system that allows access to multiple administrative services with a single ID and password. As of the end of February 2026, it is used by over 1.45 million businesses (※2) for procedures between companies and government. Furthermore, its deployment to private services is scheduled to begin in fiscal year 2027, drawing attention to its potential for use in inter-company transactions.
On the other hand, inter-company transactions still involve paper documents, seals, and face-to-face verification, which significantly hinders businesses' administrative efficiency and productivity improvement. In particular, how to achieve low-cost and highly reliable digital verification of corporate existence and confirmation of personnel authority (ensuring trust) is a common challenge for private companies.
TOPPAN has been supporting the DX of many companies by developing trust services such as identity verification and digital certificates. Leveraging this expertise, TOPPAN conducted a demonstration experiment for the private sector utilization of G-Biz ID, aiming to facilitate smooth digitalization of procedures and reduce operational burdens.
■ Overview of this Demonstration
Implementation Period
August 29, 2025 – March 31, 2026
Target Participants
6 companies across 3 industries
Objective
To verify the potential for G-Biz ID to be utilized in inter-company transactions for private service integration.
Verification Content
A prototype system connected to the G-Biz ID platform was built, and test operations were conducted for trade procedures. Additionally, a hearing survey was conducted in three fields: trade, corporate SaaS, and financial services. The effects of reducing operational burden in practical work were calculated, and technical and operational challenges were identified, verifying the potential for G-Biz ID's private sector utilization.
[Use Cases by Field]
Trade: Ensuring trust in international transactions through vLEI (※3) issuance, improving efficiency of application procedures.
Corporate SaaS: Proving corporate existence for new contracts, automating notification tasks associated with updating registration information.
Financial Services: Online acceptance of new account openings and various change procedures through collaboration with securities companies.
Confirmed Results
・Reduction in operational working hours
By automatically linking highly reliable and up-to-date corporate information using G-Biz ID, significant labor savings were confirmed in input efforts and visual checking tasks. It was estimated that the operational hours per case for service providers could be reduced by up to approximately 30%.
・High demand for utilization in inter-company transactions
The hearing survey with each company confirmed an extremely high demand for a mechanism that can acquire highly reliable corporate information guaranteed by the government.

■ Future Goals
Based on the knowledge gained from this demonstration, TOPPAN will promote secure and unified digitalization in inter-company transactions and support the revitalization of data distribution and utilization.
Furthermore, in line with the Digital Agency's plan to deploy G-Biz ID to private services in fiscal year 2027, TOPPAN will continue to develop corporate authentication and related services.
