The story
On September 9, 2026, Nagoya City, hit by record-breaking heavy rain, announced that as of 4:00 a.m. the number of damaged vehicles had reached 200. Footage of cars plunging into flooded roads and underpasses spread across social media, and on 5ch’s News Flash+ board, users debated everything from why drivers kept entering flooded areas, to the future impact on car insurance premiums, to the completion timeline for the underground rainwater retention basin Nagoya City is building.

What people said
Guess premiums are going up next year.
Only real options are dropping collision coverage or locking in a long-term policy early.
Soon flooding will just be an optional add-on for your policy.
Premium hikes for next year are already a done deal.
My insurer jacked up my rate even before my policy renewed, and other big names — the "some Marine," "some Fire," "some Adult"-type insurers (nicknames poking fun at major companies like Tokio Marine and similar) — have reportedly announced hikes regardless of the flooding.
It's not just labor costs either — as cars get more advanced, repair parts get absurdly expensive, so premiums would keep climbing even without any heavy rain at all.
I'm in an area that's currently level 3 and can't decide whether to go to the library.
Sounds like if it hits level 4 they just close the place on the spot.
It can jump straight from 3 to 5, so I'd be careful.
From what I understand, level 4 basically means "give up on large-scale evacuation."
(Moving to the second floor of your house is still fine.)
Guess they all figured it wouldn't happen to them lol
More than cars that were out driving, it's the ones parked at homes along both banks of the river that got submerged.
Just in my neighborhood alone, about 20 cars.

That's submerged enough to be affecting buildings, apartments, and shops.
This is wild! Panic! This is what "extraordinary" looks like!
I wonder what happens to basement bars and live music venues at times like this?
Gotta make sure water doesn't get in through the exhaust pipe.

Something like this.
That's so cool!!!
Kids would go nuts for that lol
If water gets into the air intake, it's game over too.
In that situation you can barely hit 20 km/h anyway, so isn't that just forcing it way too hard?
Why don't you go put yourself in that exact situation and see.
With front-wheel drive, going uphill is the real problem — and buoyancy piles on top of that.
With Chiba, the final tally ended up several times higher than the first reports. Nagoya's probably headed the same way.
If even that can't handle the weather, it's the end of the world.

That's because the building never had flood barrier panels installed.
They probably never saw flooding on this scale coming.
What do you call this, Splash Mountain?
It's called the "Nagoya Central Rainwater Retention Basin" — a tunnel built 50 meters underground starting near Nagoya Castle, designed to nearly eliminate above-floor flooding even in rainfall equivalent to the Tokai Flood (97mm per hour).
They're currently working on the section that discharges into the Nakagawa Canal, aiming for completion by the end of fiscal year 2028.
What happens if the Nakagawa Canal itself is about to overflow?
Good thing Nagoya Station's underground mall got its own flood defenses finished in time ｡･ﾟ･(ﾉД`)･ﾟ･｡
I figured it'd be finished once the work at Oshigiri Park wrapped up, but guess it's still not done.
That's terrible lol
They should put it on display at the Toyota Museum lol
aren't there a lot of spots where you can't even tell it's an underpass?
This time there was footage of people noticing just in time and backing out.
Exactly.
Especially in the tangled-up parts of cities,
underpasses are literally everywhere.
The people doing all the mocking are definitely the ones who'll end up driving into one,
because they're too busy mocking lol
Hmm, I get that for a road you're seeing for the first time, but
if it's your own neighborhood, you'd think you'd know.
Background and key points of this discussion
Nagoya City’s “Nagoya Central Rainwater Retention Basin,” targeted for completion by the end of fiscal year 2028, is planned as a tunnel running 50 meters underground from near Nagoya Castle, designed to nearly eliminate above-floor flooding even in rainfall equivalent to the Tokai Flood (97mm per hour) — but the section that discharges into the Nakagawa Canal is still under construction and wasn’t ready in time for this event. On the thread, while some voices flatly dismiss driving into flooded underpasses as reckless, others point out that how easily you can spot the danger depends on whether it’s a road you know from daily life or one you’re seeing for the first time, making this harder to reduce to simple self-responsibility. It’s also easy to overlook that heavy rain warnings can leap straight from level 3 to a much higher level without passing through the steps in between, meaning visual judgment alone may not keep up. As for car insurance, some point out that premiums keep climbing regardless of flood damage levels, driven by rising parts costs, so it would be premature to pin future premium hikes solely on this incident’s vehicle count.
