Japan updates government guidelines for generative AI procurement and use

Japan has approved Version 2.0 of The Guideline for Japanese Government’s Procurements and Utilizations of Generative AI for the sake of Evolution and Innovation of Public Administration, updating the framework that governs the use of generative AI across public administration.

The revised guidelines were approved by the Executive Board of the Council for the Promotion of a Digital Society on 12 June 2026. They replace the first edition adopted in May 2025 and reflect developments in generative AI technologies, expanding government use cases, and evolving domestic and international policy frameworks.

The document is intended to support the use of generative AI in government information systems while establishing governance, procurement, operational, and risk-management requirements. It covers generative AI models and systems, large language models, lifecycle management, procurement processes, and organisational responsibilities.

A central feature of the updated framework is the role of Chief AI Officers. Ministries and agencies are expected to designate officials responsible for overseeing AI deployment, procurement, administrative data management, operations, and risk management. These officers will coordinate AI governance across their organisations and ensure compliance with government requirements.

The guidelines also introduce a structured approach to high-risk generative AI projects. Agencies must assess potential risks using a dedicated evaluation process and report projects that are likely to be classified as high risk to the Advanced AI Utilization Advisory Board. Submissions are expected to include project objectives, risk mitigation measures, quality assurance plans, and other supporting information.

According to the government, the revisions are designed to help agencies adopt generative AI while maintaining oversight of issues such as security, data handling, reliability, and administrative accountability.

The updated guidelines form part of Japan’s broader effort to establish operational rules for AI use in the public sector as governments increasingly move from pilot projects to routine deployment of generative AI technologies.
