Torrential Rain in Chiba Prefecture Leaves 10 Dead and Hundreds Homeless

At least 10 people have died and one person remains missing following unprecedented torrential rains that battered Chiba Prefecture and eastern Japan starting Thursday evening. Local authorities reported that the deluge flooded approximately 1,300 to 1,500 homes, with some houses partially or fully destroyed. The rainfall was so severe that one weather station recorded 300 millimeters in 24 hours, making it the wettest August for the region in six decades. In Chiba City, the rainfall in 12 hours was triple the typical average for the entire month.

The disaster caused widespread infrastructure failure, including power outages and disruptions to road and rail services. At Narita Airport, 7,000 travelers were stranded on Friday. Emergency services dealt with a massive number of abandoned vehicles on flooded roads. While some reports initially estimated 1,200 abandoned cars, the Mayor of Chiba later clarified that the number reached 2,500 at its peak. Victims were found both on flooded streets and trapped inside submerged vehicles. One death was attributed to carbon monoxide poisoning, possibly from the use of a generator during a power outage.

Government officials and meteorologists described the event as unprecedented. The Japan Meteorological Agency attributed the weather to warm, moist air mixing with cold air in the upper atmosphere. Some reports linked the event to a broader pattern of regional storms, including Typhoon Dolphin. While most reports focused on the immediate humanitarian and logistical crisis, some coverage highlighted a broader scientific context, attributing the increase in such extreme weather events to human driven climate change.
