The prototype supports document searches and draft answers. Officials must verify the evidence and clear the answers.
Search is only preparation
The GENAI programme page describes a workflow that analyses parliamentary questions, retrieves previous answers and supporting records, produces drafts, anticipates follow‑up questions and checks for contradictions. Those functions help assemble an answer; an automated consistency check is not the same as deciding the government’s position.
Officials must verify the answer
The October 30 announcement requires officials to cross‑check outputs against documents for factual accuracy, consistency with previous answers and government policies, and appropriate wording. Policy judgments, official government views and final answers remain their responsibility. Ministers and other respondents will deliver answers after officials and relevant divisions review and coordinate the drafts.
Two rollout clocks
The prototype is being tested during the 222nd Extraordinary Session, with feedback informing a planned full‑scale rollout in the ordinary Diet session starting January 2027. That application timetable is separate from the broader platform plan, which places full‑scale GENAI use, with participating ministries’ budget measures, in fiscal 2027.
