NTT East and Sendai City began a trial on August 31, 2026, to see if generative AI can help disaster response decisions.
They compare AI-assisted and non-AI responses to the same disaster scenario.
The trial checks speed, decision quality, and coordination.
What happened
NTT East and Sendai City began a demonstration on August 31, 2026, testing whether generative AI can support decision-making at disaster response headquarters. They will run the same disaster scenario with and without AI assistance and compare response speed, decision quality, and coordination.
Why it matters
Disaster response requires quickly organizing information from multiple sources and prioritizing actions under time pressure. The trial will verify how AI can complement human judgment, using AI that references Sendai's regional disaster prevention plan and the Disaster Response Operation Book 47.
What to watch
The demonstration compares average response time per question, appropriateness of decisions and actions, and the accuracy of initial coordination with relevant agencies. Results will clarify the usefulness and challenges of AI in supporting on-site decision-making.

This trial builds on a May 2025 agreement between NTT East and Sendai City to strengthen disaster response in the Tohoku region, which faces risks from major earthquakes and tsunamis. The area's geography requires advance coordination with nearby agencies and efficient prioritization of limited resources during a crisis. By testing AI support against a no-AI baseline, the two organizations aim to measure whether AI can reduce delays in judgment and help maintain expertise amid staff turnover. The outcomes will inform how AI could be deployed in actual disaster operations, potentially extending beyond Sendai to other Tohoku municipalities, though the article notes that details are current as of the announcement and may change.
