You’ve probably seen the photo. It’s that terrifying, vertical slab of gray concrete that looks less like a road and more like the first drop of a Six Flags roller coaster. Usually, the caption says something about it being the "most dangerous bridge in the world" or claims drivers need nerves of steel just to cross it. It’s a great clickbait image.
But honestly? The Eshima Ohashi Bridge is a bit of a scam. At least, the version you see on social media is.
I’ve spent years looking into weird infrastructure and civil engineering marvels, and the way this bridge is portrayed online is one of the best examples of how a camera lens can manipulate reality. If you actually drive across it, you won't feel your stomach drop. You won't scream. You’ll probably just wonder when you’re going to reach the top so you can see the view of Lake Nakaumi.

The Eshima Ohashi Bridge is a rigid-frame bridge in Japan that connects Matsue, Shimane Prefecture, and Sakaiminato, Tottori Prefecture. It’s the largest rigid-frame bridge in Japan and the third-largest in the world. It’s a massive feat of engineering, but it’s not a death trap.
The Telephoto Lens Trick
So, why does it look so steep in photos?
It’s all about compression. Photographers use telephoto lenses from a significant distance—often from the Shimane side—to "squish" the perspective. By zooming in from far away, the distance between the foreground and the bridge disappears. This makes the gradient look like a 45-degree wall of death.
In reality, the gradient on the Shimane side is about 6.1%, and on the Tottori side, it’s a measly 5.1%. To put that into perspective, most highway ramps are around 4% or 5%. Some residential streets in San Francisco or even the UK hit 20% or 30%. If you can drive up a standard parking garage ramp, you can handle the Eshima Ohashi Bridge without breaking a sweat.
The bridge had to be built this high for a very practical reason: ships. Lake Nakaumi is a busy body of water, and large vessels—some over 5,000 tons—need to pass underneath it to reach the open sea. Instead of building a drawbridge, which creates traffic nightmares, the engineers just went up.
Design and Engineering Reality
The bridge stretches about 1.7 kilometers (roughly a mile). It’s made of reinforced concrete, and while it looks slender from certain angles, it’s incredibly sturdy. The "rigid-frame" (or rahmen) design means the piers and the deck are cast together as one solid unit. This is why you don't see those massive suspension cables or steel trusses that define bridges like the Golden Gate.
It's sleek. It's modern. It's also surprisingly quiet.
Construction started in 1997 and wrapped up in 2004. Before this, there was a drawbridge in its place, but it was a total bottleneck for the region's economy. Ships had to wait for cars; cars had to wait for ships. It was a mess. The Japanese government invested roughly 22.8 billion yen into this project to ensure that the logistics between the two prefectures remained seamless.
Driving the "Roller Coaster"
If you’re planning to visit, don't expect a theme park thrill. Driving across the Eshima Ohashi Bridge feels like driving up a long, steady hill.
The speed limit is 40 km/h (about 25 mph). Most people stick to it because the bridge is narrow and the wind can get pretty whipped up coming off the lake. If you’re a cyclist, though, that 6.1% grade is going to make your calves scream.
There are sidewalks. You can actually walk across the bridge. This is probably the best way to experience it because you can stop and look out over the water. From the peak—which sits about 44 meters (144 feet) above the water—you get a panoramic view of the Daisen mountain range on a clear day.
Why the Internet Is Obsessed With It
The bridge went viral back in 2014 when Daihatsu used it in a commercial for their Tanto custom minivan. The ad was designed to show off the van’s hill-start assist and engine power. They leaned into the "steep" angle using the same camera tricks I mentioned earlier. Since then, it’s been a staple of "World's Scariest Bridges" lists.
It’s funny how a piece of functional infrastructure becomes a global landmark just because someone used a long lens.
Getting There and Taking "The Photo"
If you want to recreate that famous shot, you need to head to the Matsue side (Shimane Prefecture).
- Location: Look for the intersection near the convenience stores at the base of the bridge on the Matsue side.
- Gear: You need a long focal length. A smartphone isn't going to cut it unless you have a crazy optical zoom. You’ll need at least a 200mm to 300mm lens to get that "vertical wall" effect.
- Timing: Sunset is gorgeous here, but the traffic can get heavy. Mid-morning offers the best light for showing the texture of the concrete.
Sakaiminato, the city on the other side, is also famous for being the home of Shigeru Mizuki, the creator of GeGeGe no Kitaro. The whole town is covered in bronze statues of yokai (Japanese monsters). It’s a weirdly perfect pairing: a "scary" bridge leading to a town full of monsters.
What Most People Get Wrong
People often ask if the bridge is prone to accidents because of the slope. Actually, no. Because the speed limit is low and the road surface is high-friction concrete, it’s quite safe. The real danger isn't the height; it’s the tourists who stop their cars in the middle of the road to take selfies. Don't be that person. Use the designated parking areas at the base and walk up.
Another misconception is that the bridge sways. Unlike suspension bridges, which are designed to move with the wind, a rigid-frame bridge is exceptionally stiff. You won't feel that unsettling "bounce" that you get on the Brooklyn Bridge. It feels as solid as the ground itself.
Actionable Steps for Visiting Eshima Ohashi Bridge
If you’re genuinely interested in seeing this engineering feat, don't just drive over it and leave.
- Park at the base: There are small parking lots and convenience stores on both sides. Park there and walk at least to the midpoint. The sheer scale of the concrete piers is more impressive from a pedestrian's perspective.
- Visit Sakaiminato: After crossing, spend time on Mizuki Shigeru Road. It’s one of the most unique "theme" streets in Japan and much more interesting than the bridge itself.
- Bring a real camera: If you want that viral shot, you need an SLR or mirrorless camera with a telephoto lens. Stand about 500 meters back from the base of the bridge to compress the image.
- Check the wind: If there’s a typhoon or high wind warning, the bridge might be closed to high-profile vehicles. Check local weather reports if you’re driving a camper or a tall van.
- Explore Lake Nakaumi: The bridge is just a small part of the beautiful landscape. The lake is the fifth-largest in Japan and is famous for its brackish water wildlife.
The Eshima Ohashi Bridge is a testament to Japanese engineering and its ability to solve logistical problems with bold design. It’s not a roller coaster, but it is a masterclass in how perspective can change our perception of the world. Go for the view, stay for the monsters in Sakaiminato, and laugh at the "terrifying" photos once you realize how easy the drive actually is.
