1959 Western Pacific typhoon season
Typhoon Vera 1959
Typhoon Vera, known in Japan as the Isewan Typhoon, brought catastrophic flooding and storm surge in September 1959. Thousands died as coastal defenses failed and low-lying communities flooded. The disaster prompted lasting changes to Japan's emergency planning and coastal protection.

STORM HISTORY
Rapid intensification and the turn toward Japan
Vera developed between Guam and Chuuk on 20 September. It intensified rapidly over the following days, reaching a minimum archived pressure of 895 hPa and peak one-minute winds of 165 kt on 23 September. It then curved north and accelerated toward Japan.
On 26 September, Vera came ashore near Shionomisaki on Honshu. The current archive records 125 kt at the sampled center-over-land position at 09:00 UTC. It crossed the island, emerged into the Sea of Japan and turned east for another passage across Honshu before losing its tropical character.
Coastal defenses overwhelmed
Rain began flooding river basins before Vera reached land. The storm then drove a destructive surge into coastal areas, breaching flood defenses and sinking ships. Limited communications and insufficient public urgency hindered evacuation despite forecasts of the approaching typhoon.
The disaster killed about 5,000 people, injured nearly 40,000 and displaced around 1.6 million. Damage estimates reached US$600 million in 1959 dollars. Floodwater and debris obstructed relief crews, and outbreaks of disease added to the suffering in inundated communities.
Relief and national reform
Japanese and American authorities mobilized relief after the storm. Vera's losses also led lawmakers to strengthen disaster management. The Disaster Countermeasures Basic Act of 1961 established a framework for coordinated response and the Central Disaster Prevention Council.

QUICK ANSWERS
Vera in brief
What was Typhoon Vera's highest wind speed?
190 mph, the highest one-minute sustained wind in its tropical stage, recorded on Sep 23, 1959, 12:00 PM UTC.
What category was Typhoon Vera?
Category 5 at its peak on the Saffir–Simpson one-minute wind scale, first reaching Category 5 on Sep 23, 1959, 06:00 AM UTC. Other agencies classify storms differently.
What was Typhoon Vera's lowest pressure?
895 mb, the minimum central pressure recorded during its tropical stage, on Sep 23, 1959, 06:00 AM UTC.
When did Typhoon Vera occur?
The archived track runs from Sep 20, 1959, 12:00 AM UTC to Sep 29, 1959, 12:00 PM UTC, with the tropical stage from Sep 20, 1959, 12:00 AM UTC to Sep 27, 1959, 03:00 AM UTC.
Where did Typhoon Vera form?
In the Western Pacific basin, in the 1959 season. Its first archived position is 11°N, 160°E on Sep 20, 1959, 12:00 AM UTC.
Did Typhoon Vera make landfall?
The archive places its center over land at 2 recorded positions; the strongest is 144 mph on Sep 26, 1959, 09:00 AM UTC. Positions are six-hourly, so this is not a landfall chronology.
METHODOLOGY
Data sources and limitations
The map and summary are generated from NOAA's IBTrACS v04r01 archive. Wind and category use US-agency records; minimum pressure is calculated during the tropical stage, with the archive's pressure source retained. Category 5 refers to the Saffir–Simpson one-minute wind scale; local agencies may use different classifications. Coastlines use Natural Earth's 1:10m land data.
Track distance adds great-circle distances between consecutive observations, excluding gaps over 12 hours. This track has no gaps over 12 hours. The line shows the storm's center, not its size, rainfall or flood extent. Converted wind speeds are rounded to the nearest whole unit.
