Between August 10 and 15, 2025, Kyushu, particularly Kumamoto Prefecture, experienced record-breaking heavy rainfall resulting in widespread flooding and landslides. The Japan Meteorological Agency issued multiple special heavy rain warnings and alerts for Kumamoto, including for cities such as Yatsushiro, Uki, Amakusa, Misato, and Hitoyoshi, as well as for Nagasaki Prefecture's southern region. Intense rainfall rates reached approximately 110 millimeters per hour in several locations, prompting emergency evacuation orders (warning level 5) for tens of thousands of residents across affected municipalities. The heavy rain caused rivers to overflow and triggered landslides, leading to casualties and missing persons. As of August 15, six deaths were confirmed in Kumamoto, Fukuoka, and Kagoshima Prefectures, including two people found in a state of cardiopulmonary arrest in Kumamoto and two bodies discovered offshore near Munakata City in Fukuoka, identified as missing persons from Fukutsu City. Several individuals remain unaccounted for, with four reported missing in Fukuoka and Kumamoto. Floodwaters inundated approximately 1,200 homes in Kumamoto City, and emergency services continue search and rescue operations. Concurrently, multiple earthquakes with magnitudes up to seismic intensity 4 were recorded in regions including Ibaraki, Hokkaido, Kagoshima, Miyagi, Fukushima, and Shizuoka Prefectures, though no tsunami warnings were issued. Additional heavy rain and landslide warnings were issued for Niigata, Toyama, Hyogo, and other prefectures. The ongoing severe weather has prompted authorities to urge residents in affected areas to take appropriate safety measures and evacuate as necessary.
