Nagasaki sits on Kyushu, Japan’s southernmost main island, which typically takes the country’s earliest and most direct typhoon landfalls of the season, with a rainy season that begins earlier than the rest of Japan.
Built around a narrow harbor on Kyushu’s western coast, the city’s steep hillside neighborhoods are prone to fast runoff during the region’s heavy typhoon rains. Because Kyushu is often the first part of Japan a typhoon reaches, radar imagery is closely watched here in the hours before landfall, and the Japan Meteorological Agency’s regional radar network covers Nagasaki.
