Three Unique Experiences Only at Uzu no Michi Above the Whirlpools
The Naruto Strait is home to some of the largest whirlpools in the world. Suspended directly above this powerful natural phenomenon is Uzu no Michi, a glass-floored walkway offering a one-of-a-kind viewing experience.
From thrilling views of the whirlpools from above, to the rare experience of walking inside a bridge structure, and the sweeping vistas over the Seto Inland Sea—this walkway offers more than just sightseeing.
This article highlights the top three must-see features at Uzu no Michi, along with tips on the best viewing times and how much time to plan for your visit.
Uzu no Michi Walkway on the Onaruto Bridge
Uzu no Michi is a 450-meter-long observation walkway built beneath the Onaruto Bridge in Naruto City, Tokushima Prefecture, suspended approximately 45 meters above sea level. It’s a popular attraction that lets you observe the Naruto Whirlpools—considered among the world’s three largest tidal currents—from directly above.

Feel the Power of the Whirlpools Directly Below You
The whirlpools of the Naruto Strait can reach diameters of 20 to 30 meters, with tidal currents exceeding 20 km/h, making them among the largest in the world. During the spring tide, you can witness massive whirlpools forming right beneath your feet.
These whirlpools occur due to a combination of gravitational forces from the moon and sun, the unique V-shaped geography of the strait, and a deep underwater depression called a “kaifu” reaching over 90 meters in depth. These conditions create intense tidal currents that form whirlpools.
Several observation points with transparent floors along the walkway and viewing rooms allow you to look directly down at the sea. With good timing, you might catch a massive whirlpool swirling beneath your feet.
Stunning Coastal Views from the Walkway Above the Inland Sea
As you walk along Uzu no Michi, panoramic views of the Naruto Strait and Seto Inland Sea unfold before you. Unlike observation decks or sightseeing boats, this bridge-level perspective offers a unique angle only possible here. On clear days, you can see as far as Awaji Island and other nearby islets while enjoying the ever-changing sea patterns created by the tide.
Rest areas are located every 100 meters along the walkway, where you can take a break and admire the ocean expanse from benches. Pause along the way to fully take in the beauty of this seascape—it’s like stepping into a painting.
The walkway’s mesh flooring allows sea breezes to flow through. It feels cool in summer, but be sure to dress warmly during winter.
Surrounded by Engineering Marvels: Walk Inside a Giant Bridge
The Uzu no Michi walkway runs inside the massive steel framework of the Onaruto Bridge. Near the end of the walkway, you’ll see thick beams arranged in complex lattice patterns, creating an overwhelming sense of scale.
Normally only visible from afar, the bridge’s internal structure can be explored up close here. These geometric frameworks extend into the distance, evoking the atmosphere of a movie set or a sci-fi world.
The sound of wind passing through and the rushing tide below create an immersive atmosphere where nature and massive man-made structures coexist. This experience of walking inside structural beauty is one of the highlights unique to this spot.
When Is the Best Time to See the Whirlpools Up Close?
Timing is everything when visiting Uzu no Michi. Whether or not whirlpools form in the Naruto Strait depends on two main factors:
- Whether it’s around high tide or low tide
- The size of the tide (spring, medium, or neap tides)
Whirlpools tend to form before and after both high and low tides due to tidal currents created by the gravitational pull of the moon and sun.
In particular, during low tide, whirlpools are more likely to form on the Naruto (Tokushima) side of the strait, offering a better chance to view them directly from Uzu no Michi.
The size of the tide is also crucial.
Tide strength ranks from largest to smallest as: Spring tide > Medium tide > Neap tide. Spring tides are your best bet for seeing large and long-lasting whirlpools.
Here’s a general guide for best viewing times by tide type:
- Spring tide: Around 2 hours before and after high or low tide
- Medium tide: About 1.5 hours before and after
- Neap tide: About 1 hour before and after
Because the best time varies daily, be sure to check the official Uzu no Michi tide chart before your visit.
Time Required and Access Information
Plan for about 30 minutes to 1 hour for your visit. If you walk through quickly, 30 minutes may suffice. But if you stop for breaks, take photos, and read the informational panels, expect closer to an hour.
The walkway is 450 meters long. It includes a round trip walk, an observation room at the far end, and several rest areas every 100 meters with educational displays. When I visited and explored at a leisurely pace, it took me about 45 minutes.
If you’re coming by car, the nearest parking lot is Naruto Daiichi Parking, about a 5–7 minute drive from the Naruto-kita IC. From the parking lot, it’s approximately a 5-minute walk to the entrance of Uzu no Michi.

Three Unforgettable Experiences Only at Uzu no Michi
Uzu no Michi is more than a place to observe whirlpools—it offers breathtaking sea views, awe-inspiring bridge engineering, and the rare chance to walk inside a massive bridge. This walkway engages all your senses with shifting sea colors, open skies, and the scale of the man-made structure around you.
Unlike sightseeing boats that view whirlpools from the water’s surface, Uzu no Michi offers a top-down perspective that blends the movement of nature with human engineering. As you walk among the steel beams supporting the bridge, the salty breeze and dramatic scenery immerse you in a powerful, one-of-a-kind experience.
If you’re visiting Tokushima or the Naruto Strait, don’t miss the chance to walk above the whirlpools at Uzu no Michi.
