Japan and South Korea: Record Rains Trigger Deadly Floods

Record-breaking rainfall in Japan and South Korea has led to devastating floods, claiming at least 13 lives and displacing over 100,000 people. The extreme weather event, which began late last week, saw Chiba City near Tokyo record 115mm of rainfall in just one hour on August 13, breaking all previous records. Nearby Sakura City also reported an unprecedented 97mm in the same timeframe.

Local authorities issued a level five emergency warning—the highest alert level—marking the first time such a warning has been used since its implementation in May. The deluge left more than 20,000 households in Chiba Prefecture without power and stranded thousands at Tokyo’s Narita Airport. At least three victims were found trapped in their vehicles, with one person still missing as of the latest reports. Source: The Guardian, August 21, 2026.
