History

Historical Context

The 2026 magnitude-7.1 Kumamoto quake that prompted Prime Minister Sanae Takaichi to form a national task force echoes the 2011 Tohoku disaster, when Prime Minister Naoto Kan mobilized the Self-Defense Forces after a 9.0 quake and tsunami. That event displaced roughly 336,000 people and spurred nationwide upgrades to early-warning and coastal-defense systems.
