You’ve probably seen the photo. It’s a terrifying, near-vertical slab of concrete that looks less like a road and more like a logic-defying leap of faith into the clouds. People call it the Eshima Ohashi Bridge, and in those viral snapshots, it looks like a death trap for anything less powerful than a NASA rocket.
But honestly? It’s a lie.
Well, not a "lie" lie, but a massive optical illusion that has basically tricked the entire internet for over a decade. If you drove across it expecting the thrill of a lifetime, you’d probably be a little disappointed—or relieved, depending on how much you value your brake pads.
The Reality of the "Rollercoaster" Gradient
So, how steep is it actually?
The bridge connects Matsue in Shimane Prefecture to Sakaiminato in Tottori Prefecture. If you’re coming from the Shimane side, the gradient is 6.1%. From the Tottori side, it’s even shallower at 5.1%.
To put that in perspective, a 6% grade means for every 100 meters you travel horizontally, you rise about 6 meters. It’s steep, sure. If you’re riding a bicycle, you’re definitely going to be standing on the pedals and questioning your life choices. But for a modern car? It’s a breeze. You don’t need a "betabumi" (pedal to the metal) approach despite the local nickname Betabumizaka.
Most mountain passes in the US or Europe have sections much steeper than this. San Francisco’s Filbert Street, for instance, hits a 31% grade. Compared to that, Eshima Ohashi is practically a flat parking lot.
Why Does It Look So Scary in Photos?
The "scary" version of the Eshima Ohashi Bridge is a masterclass in telephoto lens compression.
Photographers who want that viral shot don't stand at the base of the bridge. They go way, way back—sometimes over a kilometer away—and use a massive zoom lens (think 400mm or more).
When you zoom in from a huge distance, the foreground and the background get squashed together. The horizontal distance of the bridge (about 1.7 kilometers) basically disappears, leaving only the vertical height. It’s the same trick used to make a giant moon look like it's sitting right behind a skyscraper.
If you want to see the "fake" steepness for yourself, the classic spot is near the convenience store intersection on the Shimane side. From there, looking straight down the barrel of the bridge, the road appears to climb at a 45-degree angle.
Move just a few hundred yards to the side, though, and the illusion shatters. You’ll see a long, graceful concrete arch that looks... well, like a normal bridge.
The Engineering Behind the Arch
Japan didn't build this thing to scare tourists. It was a matter of practical necessity.
Before the bridge opened in 2004, the two cities were connected by a drawbridge. That sounds fine in theory, but in practice, it was a nightmare. Every time a large ship needed to pass through Lake Nakaumi, traffic would grind to a halt for seven to eight minutes. In an industrial area where time is money, that wasn't going to cut it.
The solution was a rigid-frame bridge (or "Rahmen" bridge in German/Japanese engineering terms).
Quick Specs
- Total Length: 1.7 km (about 1.1 miles)
- Max Height: 44.7 meters (roughly 147 feet)
- Main Span: 250 meters of continuous concrete
- Material: Prestressed concrete
Building it that high allowed 500-ton ships to pass underneath without anyone having to wait for a drawbridge to lower. It’s actually the largest rigid-frame bridge in Japan and the third largest in the world. Engineers used a box-girder design to ensure it could handle the heavy truck traffic between the two industrial hubs while remaining flexible enough to survive earthquakes.
What It’s Actually Like to Drive
I’ve talked to people who visited expecting a white-knuckle experience. Most of them say the same thing: "That's it?"
Driving over the Eshima Ohashi Bridge is actually quite pleasant. The road is wide (about 11 meters) and the pavement is high-grip. Because it’s so high up, the views from the crest are actually the real highlight, not the incline. On a clear day, you can see Mount Daisen—often called the "Mt. Fuji of the West"—looming in the distance.
The water of Lake Nakaumi glitters below you, and the whole experience feels remarkably stable. There’s no swaying, no "stomach-drop" feeling.
If you’re walking or cycling (there is a pedestrian path), that’s where you’ll actually feel the burn. It’s a 1.5-kilometer trek to the top, and while it's safe, the wind can get pretty whipped up at 45 meters in the air.
How to Get the Shot Without the Crowds
If you’re heading there to see if the hype is real, here’s the actual "expert" way to do it.
Most tourists crowd the Shimane side intersection. Don't do that. Instead, head to the Sakaiminato side (Tottori) and find a spot along the coast of the lake. If you have a decent zoom lens, you can capture the bridge silhouetted against the sunset.
Also, Sakaiminato is the hometown of Shigeru Mizuki, the creator of GeGeGe no Kitaro. The whole town is covered in bronze statues of yokai (Japanese monsters). It’s a much better way to spend your afternoon than standing in a Lawson’s parking lot staring at a bridge that isn't as steep as the internet promised.
Actionable Takeaways for Your Visit
- Bring a telephoto lens: If you want that "vertical" photo, a phone camera won't cut it. You need a focal length of at least 200mm-300mm to get the compression effect.
- Rent a bike in Sakaiminato: It’s a flat, easy ride from the station to the bridge, and you can cross it on two wheels for a better view than you’d get through a car windshield.
- Check the weather: High winds sometimes close the bridge to tall vehicles or cyclists.
- Time your visit: Sunrise and sunset are the only times the bridge looks truly "epic." During the harsh midday sun, it just looks like a gray highway.
The Eshima Ohashi Bridge is a testament to Japanese engineering and the power of a good camera angle. It’s a vital piece of infrastructure that just happened to become a celebrity. Just don't expect a theme park ride when you get behind the wheel.

Key Travel Stats
- Closest Station: Sakaiminato Station (JR Sakai Line).
- Access: About a 10-minute drive or 20-minute bike ride from the station.
- Cost: Free (no toll).
- Best Viewpoint: Intersection near "Eshima" on the Shimane side.
If you’re planning a trip, combine this with a visit to the Adachi Museum of Art or Matsue Castle. Both are within a 40-minute drive and offer a much deeper look into the culture of the San’in region than a single bridge ever could.
