History

Historical Context

The 1959 Isewan Typhoon (Vera) killed over 5,000 people and spurred Japan’s Disaster Countermeasures Basic Act of 1961, prompting systematic upgrades to flood defenses. Decades of reforms reduced typhoon deaths to under a dozen per event, yet the 2024 Typhoon Dujuan dumped a record 832 mm on Oshima Island, forcing Japan Airlines and ANA to cancel over 250 flights and reviving calls for further drainage investment.
