Japan to Roll Out Government-Built AI Tool to Ease Bureaucrats' Workload
Japan's central government will deploy a generative AI platform across all ministries by the end of March. The system, called Gennai, was built by the Digital Agency to cut routine drafting time and ease overtime pressure on senior staff. Update: 11:00 PM GMT+8, January 14, 2026.
What's being deployed
Gennai is an internally developed AI platform that can draft responses, propose follow-up answers, and support administrative work. It has already been tested by select bodies, including the Digital Agency, and is now moving to full rollout across national ministries and agencies.
Because it's government-built, Gennai can access certain highly confidential data that commercial tools cannot touch. Officials are also exploring how it could extend to local governments next.
Why it matters for government teams
Central government bureaucrats average 376 hours of overtime per year-more than double the 181-hour average across other public-sector employees, according to the National Personnel Authority. A major driver is the labor-intensive process of preparing multiple versions of draft answers for Diet questions and anticipated follow-ups.
- Gennai can generate first-draft responses and suggest answers to likely follow-ups; staff review and refine before submission.
- Ministries can build specialized AI agents trained on Diet minutes, lawmakers' written inquiries, and historical government responses.
- Beyond legislative support, AI will be used for administrative tasks like licensing and permitting.
- A pilot is underway to review applications from companies seeking certification for workplaces that support women and parents of young children.

How to prepare your ministry or agency
- Map the first three workflows for AI support: Diet Q&A drafting, correspondence templates, and permit/licensing reviews.
- Set a clear human-in-the-loop policy: who approves, what thresholds trigger manual review, and how exceptions are escalated.
- Assemble training corpora now: relevant Diet minutes, prior answers, FAQs, guidance notes, and policy briefs-remove outdated content.
- Define data access tiers so Gennai only sees what it needs for each use case; log every data touch for auditability.
- Create prompt templates and style guides for consistent tone, legal accuracy, and citation of sources.
- Stand up a review board (policy, legal, security, records management) to monitor quality, privacy, and records retention.
- Run accuracy and bias checks on a weekly sample of outputs; track error types and feed fixes back into prompts and datasets.
- Plan training for staff: when to use AI, when to stop and ask a colleague, and how to give feedback to improve outputs.
Guardrails and risks to manage
AI can draft fast, but it can also be confidently wrong. Protect sensitive data, avoid policy drift, and keep trust by making review and record-keeping non-negotiable.
- Require citations to source passages for high-stakes answers; no citation, no submission.
- Watermark drafts and label them "AI-assisted" until approved; keep final human sign-off visible.
- Log prompts, model versions, and outputs for each case; retain per your records schedule.
- Use red-team tests on sensitive topics to find failure modes before public release.
- Set safe defaults: if the model is uncertain, it should ask for clarification rather than guess.
Timeline and what's next
Rollout is scheduled for completion by the end of March. Ministries can start now by identifying priority use cases, preparing datasets, and defining approval paths. Local government adoption is under study, so early lessons at the national level will help create a repeatable playbook.
