Tokyo Releases AI Simulation of Mount Fuji Eruption to Push Preparedness

Officials say the AI video is a preparedness tool, not a sign of imminent activity.

Overview

  • The three-minute, AI-generated clip from Tokyo’s Disaster Prevention division anchors a new Fuji-focused web portal launched on August 22.
  • The scenario shows ash reaching the capital in under two hours, with potential blackouts, telecom failures, transport paralysis and health risks.
  • Residents are urged to store at least two weeks of water, nonperishable food and basic supplies to ride out early disruptions.
  • Models cited by media estimate more than 1.7 billion cubic meters of ash ejected, about 500 million settling on infrastructure, and economic losses near ¥2.5 trillion.
  • The portal outlines expected ash fall across parts of Tokyo, Chiba, Shizuoka and Yamanashi, and officials emphasize there are no current signs of an imminent eruption.
