Tokyo Warned: Major Quake Could Cost $535 Billion and 18,000 Lives

A new Japanese government report warns that a powerful earthquake directly hitting the Tokyo metropolitan area could cause catastrophic damage. The official estimate projects up to 18,000 fatalities and economic losses exceeding 80 trillion yen ($535 billion). The assessment models a magnitude 7.3 tremor striking the capital region during a winter evening. This scenario anticipates widespread fires, building collapses, and transportation paralysis. Up to 4.5 million people could be stranded in the aftermath. These projections update a 2013 estimate, which forecast higher casualties but lower economic cost. Officials cite increased asset values and supply chain complexity for the rise in potential financial damage. The report aims to accelerate disaster preparedness. Authorities urge residents to secure furniture, stockpile supplies, and plan family reunification strategies. The government is prioritizing fire prevention measures and the reinforcement of critical public infrastructure.
