Japan’s government revises its disaster-preparedness plan for a potential megaquake affecting the Tokyo area, aiming to substantially reduce both deaths and physical destruction compared with recent estimates. Across reporting, the updated approach focuses on lowering expected earthquake losses to at least half of the latest projected figures. One emphasized measure in the revised plan is broader deployment of seismic circuit-breakers in residential buildings. The Independent reports that the government seeks installation of seismic circuit-breakers in all homes by 2035, a step intended to help limit fires and other earthquake-related secondary hazards. The Japan Times similarly describes the overarching goal of cutting casualties and the number of buildings damaged or burned to at least half of the current estimate baseline, reflecting a shift in preparedness targets and implementation details. While the outlets differ in how much they spell out specific components, they align on the central update: Japan is tightening its megaquake preparedness targets for the Tokyo region, with the revision anchored in reducing expected loss of life and property through additional protective measures over time.
