On Tuesday, the city of Nagoya experienced catastrophic flash flooding after a staggering 104.5 millimeters of rain fell within an hour, marking the highest hourly total since records began in 1890. The relentless downpour overwhelmed the city's drainage systems, submerging streets, vehicles, and homes, leaving at least four individuals with minor injuries.
The Japan Meteorological Agency (JMA) issued a Level 5 flood warning for the Shonai River, prompting the Nagoya city government to urgently advise residents in Chikusa, Meito, and Moriyama wards to take immediate safety measures. Approximately 2,700 people sought refuge in evacuation shelters as authorities urged all citizens to evacuate to safer locations.
The unprecedented rainfall disrupted transportation and daily life, with several roads and rail services affected by the flooding. The Tokaido and Sanyo Shinkansen lines saw partial suspensions due to heavy rain, while local train services and certain bus routes were also halted. Efforts to prepare for the upcoming Asian Games, set to commence in Nagoya on September 19, were hampered as athletes staying at the Garden Pier accommodation in Minato ward were temporarily evacuated, and multiple competition venues reported water leaks.
However, the athletes later returned following the evacuation order's lifting. Meteorologists forecast that heavy downpours will persist across vast areas of Japan, with up to 250 millimeters of rain anticipated in the Kanto and Shikoku regions within the next 24 hours, and up to 200 millimeters expected in the Tokai and Kinki regions.
