TOKYO, Sept. 20 (Xinhua) -- About 1.2 million people in western and central Japan have been advised by the government to evacuate due to threats of flooding caused by an approaching typhoon, according to the meteorological authorities.
In the central city of Nagoya, some 1 million people have been asked to leave home where the rising water levels of the nearby rivers are posing risks.
Japan's Meteorological Agency (JMA) warns that heavy rainfall brought by the approaching typhoon Roke could trigger landslides and floods in western and central Japan, parts of which saw hourly rainfall between 30 and 40 millimeters on Tuesday evening.
Weather authorities say Roke is picking up speed and is set to approach western and eastern Japan on Wednesday.
