Typhoon Kong-rey, now classified as a severe tropical storm, is causing record high temperatures for October in wide areas across Japan.
The Meteorological Agency says unusually hot temperatures were recorded on Saturday mainly in the Hokuriku, Shikoku and Chugoku regions as hot southern air was drawn to the typhoon.
In Sanjo City in Niigata Prefecture, the temperature hit 36 degrees Celsius -- the highest ever in Japan for October. Other cities in Niigata also saw the thermometer rise above 35 degrees.
Takamatsu City in the Shikoku region registered 34 degrees.
Weather officials are calling on people to take precautions against heatstroke.
