“The record rainfalls in various parts of the country have caused rivers to burst their banks, and triggered large-scale floods and landslides in several areas,” Cabinet Secretary Yoshihide Suga said Sunday.

Hundreds of homes have been destroyed or damaged. In all, eight prefectures have been affected, including Kyoto and Hiroshima.

“I went to my father’s family home but it was hopeless,” one man said. “We were hoping to find two people but still can’t find one.”

The Japan Meteorological Agency upgraded its alert system to the highest level in large areas of western Japan, while lifting the warning in other regions.

Japanese public broadcaster NHK reported about 364 millimeters (14.3 inches) of rain fell between 5 a.m. and 7 a.m. in the city of Uwajima — approximately 1.5 times the average monthly rainfall for July.

In Sukumo City in Kochi prefecture, 263 millimeters (10.3 inches) of rain fell in two hours, NHK reported.

At least 4 million people have been advised to evacuate surrounding areas.
