Japan Floods: Ueda River Bursts Its Banks in Nagoya as Record‑Breaking Rain Drowns Streets

On Tuesday afternoon a cloudburst slammed Nagoya, dumping an astonishing 104.5 mm of rain in just 60 minutes – a record for the city, according to the Japan Meteorological Agency. The sheer volume of water overwhelmed drains, forcing the Ueda River to spill over its banks.

Water rushed onto streets in the Chikusa, Moriyama and Meito wards, turning ordinary roads into shallow rivers. Drivers found their cars bobbing up to the door frames, some even having to abandon them as the current grew stronger. Social‑media clips show water lapping at wheels, headlights blinking under a sheet of gray.

In response, Nagoya’s authorities raised the alarm to a level‑5 emergency warning – the highest tier. Residents were told, in plain language, to grab whatever they could and head for higher ground, whether that meant climbing to a higher floor of their home or seeking shelter in a sturdy building.

Officials also warned people to stay clear of underground spaces – underpasses, shopping arcades and subterranean parking lots can fill up like a bathtub in minutes when the drainage system is overloaded. Luckily, despite the chaos, no one was reported trapped inside a vehicle.

The flood has snarled traffic, halted public transport and left a few neighborhoods looking like a post‑storm set‑piece. Clean‑up crews are already on the way, and meteorologists say more rain isn’t out of the question, so the city remains on high alert.

If you’re in the affected wards, keep an eye on local updates, avoid low‑lying streets, and, above all, stay safe. The situation will evolve, but for now the priority is getting everyone out of the water and into dry, secure places.
