Ueda River Bursts Its Banks in Nagoya as Record Rain Drenches the City

On Tuesday afternoon a wall of water slammed into Nagoya when the Ueda River suddenly swelled beyond its banks. It wasn’t just a heavy shower – the Japan Meteorological Agency logged a staggering 104.5 mm of rain in a single hour, a record for the city.

That downpour overwhelmed the drainage system in a flash. Roads in the Chikusa, Moriyama and Meito wards turned into shallow rivers, and drivers found their cars bobbing up to the doors. Some people even had to abandon their vehicles, wading through waist‑deep water that rushed around them. Social‑media clips showed headlights flickering under rising floodwater, a stark reminder of how quickly conditions can change.

In response, Nagoya’s disaster office fired off a Level‑5 emergency warning – the highest alert the city uses. Residents were urged to move immediately to safer ground, preferably higher floors or sturdy buildings. Authorities also warned against staying in underground passages, shopping malls or parking garages, where water can surge in minutes.

Thankfully, no one was trapped inside a vehicle, and there have been no reports of serious injuries so far. Nevertheless, the city remains on high alert as more rain is possible, and officials continue to monitor river levels around the clock.

For anyone caught in the affected neighborhoods, the advice is simple: avoid low‑lying streets, steer clear of underpasses, and head to higher ground if the water keeps rising. The heavy rain has turned a busy weekday into a race against the rising tide, reminding everyone how powerful nature can be when it decides to pour.
