Typhoon Nancy Makes Landfall

Date: September 16, 1961 • Location: Muroto, Japan

Typhoon Nancy (pictured), which possibly had the strongest winds ever measured in a tropical cyclone, made landfall in Muroto, Japan.

Super Typhoon Nancy, also known as the 2nd Muroto Typhoon , was an extremely powerful tropical cyclone of the 1961 Pacific typhoon season, produced the highest accumulated cyclone energy—a metric used to measure the total energy generated by tropical cyclones—of any individual cyclone on record in the basin, also one of the most intense tropical cyclones on record. The system possibly had the strongest winds ever measured in a tropical cyclone, with 345 km/h (215 mph) winds, tied with Hurricane Patricia of 2015. Nancy caused extensive damage, as well as at least 202 deaths and nearly 5,000 injuries in Japan and elsewhere, in September 1961.
