Heavy rain lashed wide areas of Japan on Friday, including in Kyushu, Kansai and Kanto, with authorities urging residents to be on alert for flooding and mudslides.

The heavy precipitation came as the rainy season began in much of western and central Japan. The active rain front, as well as moist air carried by Tropical Storm Mawar as it moves through the Pacific south of Japan, brought heavy rain in areas from Shikoku to Tokai along the Pacific coast.

The Meteorological Agency reported record rainfall in two municipalities in the six hours through 4:20 p.m., with 291 millimeters falling in part of Tosashimizu in Kochi Prefecture and 229 mm in Shinshiro in Aichi Prefecture.
