Devastating Flood Hits Yokkaichi’s Underground Parking
In the midst of Japan’s unpredictable autumn weather, Yokkaichi City in Mie Prefecture faced a harrowing ordeal on September 12, 2025. What began as a heavy downpour quickly escalated into record-breaking rainfall, transforming bustling urban streets into raging torrents. At the heart of the chaos was the Kusunoki Parking lot, a large underground facility adjacent to Kintetsu Yokkaichi Station. This vital hub for commuters and shoppers became a submerged disaster zone, with floodwaters claiming 180 cars and leaving the second basement level completely underwater. As of September 14, recovery efforts are ongoing, highlighting the vulnerabilities of modern infrastructure in the face of extreme weather events.

Yokkaichi, known for its industrial prowess and stunning night views over Ise Bay, is no stranger to seasonal rains. However, this storm shattered local records with an astonishing 123.5 millimeters of rain falling in just one hour – the highest ever recorded in the area. Fueled by warm Pacific air masses, the deluge overwhelmed drainage systems, leading to flash floods across central districts like Chuo-dori and along National Route 1. Social media buzzed with dramatic footage: vehicles bobbing in floodwaters, pedestrians wading through knee-deep streams, and even a daring escape by a Suzuki Jimny slicing through the chaos like a scene from an action film. Eyewitnesses described the scene as surreal, with rainwater cascading into underground spaces unchecked.
The Kusunoki Parking lot, an L-shaped structure capable of accommodating up to 510 vehicles, sits beneath key roadways, making it particularly susceptible to runoff. Managed by a local company, it’s a daily lifeline for train users and downtown visitors. But on that fateful day, the absence of nearby rivers meant no natural outlet for the water – instead, it pooled rapidly due to urban impermeable surfaces. Reports indicate the entrance was designed to accommodate flood barriers, yet they were never installed, raising questions about preparedness and potential oversights. By the time the rain subsided, the first basement level showed water marks ranging from 50 centimeters to a full meter, with some cars displaced from their spots by the forceful currents.
Recovery kicked off swiftly. The Mie River and National Highway Office under the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) mobilized pumps starting around noon on September 13. Up to four pump trucks worked tirelessly, diverting water into the city’s sewer system after coordination with local authorities. By the morning of September 14, the first basement was fully drained, revealing 45 cars stranded under National Route 1 and 135 beneath Chuo-dori. Tragically, the second basement remains fully submerged, with no clear timeline for completion as officials note the complexity of the task. “At this point, we can’t predict when the work will finish,” a spokesperson from the office stated.
The human impact extends beyond damaged vehicles. Evacuation orders were issued for over 57,000 residents in Yokkaichi and nearby Inaba, underscoring the broader threat to public safety. While no injuries were reported directly from the parking lot incident, the event disrupted daily life, forcing businesses to close and commuters to seek alternatives. In a culturally resilient nation like Japan, where community and preparedness are valued, this flood serves as a wake-up call. It echoes similar incidents across the country, where aging infrastructure meets intensifying storms linked to climate change. Experts point to rising sea levels and erratic weather patterns as exacerbating factors, urging cities to invest in resilient designs like elevated barriers and advanced drainage.
For car owners, the aftermath is daunting – insurance claims, towing, and repairs loom large. Yet, stories of community solidarity emerge: locals sharing escape tips online and volunteers aiding cleanup. As Yokkaichi rebounds, this event reminds us of nature’s power and the need for proactive measures in urban planning.
