FUKUOKA -- Torrential rain lashed the southwestern Japan prefecture of Nagasaki on the morning of June 25 as a seasonal rain front in northern areas of Kyushu left atmospheric conditions unstable.

Over 120 millimeters per hour of rain fell on the city of Sasebo in Nagasaki Prefecture up until 6:10 a.m., while an area near the town of Hasami in the prefecture saw around 110 millimeters per hour of rain, according to the Japan Meteorological Agency.

By 9 a.m. on June 25, the 24-hour rainfall in Sasebo reached a record high for the month of June of 281.5 millimeters.

The agency said extremely heavy rain with localized thunderstorms could hit northern Kyushu through June 26. The agency called for caution, saying that Nagasaki Prefecture, in particular, was getting levels of rain "seen only about once in 50 years."
