Weather officials in Japan are warning that heavy rain could cause landslides and flooding in low-lying areas across the country.
The Meteorological Agency says warm, damp air blowing into the seasonal rain front is bringing heavy rain mainly to the southwestern island of Kyushu.
Kagoshima Prefecture had over 300 millimeters of rain in 24 hours. Rain is expected to intensify and continue into Monday afternoon in Kyushu and parts of western Japan. Some areas could see more than 50 millimeters of rainfall per hour.
Officials have issued evacuation advisories for more than 1 million people in Kagoshima, Kumamoto, Miyazaki and Ehime prefectures.
Weather officials say the front will linger and bring heavy rainfall mainly to Kyushu until midweek.
