The Scale of the Whirlpools

Whirlpools occur around high and low tides, sometimes reaching over 20 m in diameter. Peak timing changes daily, so planning with a tide table helps you visit efficiently.

Uzunomichi is a roughly 450 m walkway, and looking straight down through the glass sections gives a thrilling view of the currents below. It can be windy, so keep belongings to a minimum.

At the viewing deck near the end, you can take in the strait and learn about how whirlpools form (driven by tidal changes) through exhibits. It adds understanding beyond photos alone.

What Are the Naruto Whirlpools? (Naruto Travel Guide)

The Naruto Whirlpools are a world-famous natural phenomenon that occurs in the Naruto Strait between Naruto City, Tokushima Prefecture, and Awaji Island in Hyōgo Prefecture.

During spring tides, larger whirlpools can appear, letting you witness powerful currents up close.

One of the best ways to see them is on the Ōnaruto Bridge Promenade “Uzu no Michi,” a walkway built inside the bridge structure.

Looking down through glass-floor panels from about 45 meters above sea level is breathtaking, and it’s an experience you won’t forget.


Highlights of the Ōnaruto Bridge Promenade “Uzu no Michi”

1. A 450 m Ocean Walkway

“Uzu no Michi” is an ocean walkway about 450 meters long, built using space within the Ōnaruto Bridge structure spanning the Naruto Strait.

There are eight glass-floor panels in total, located along the walkway and in the observation room at the end, allowing you to walk while looking straight down at whirlpools and tidal currents from about 45 meters above the sea.

If you’re afraid of heights, it may feel a bit thrilling, but the glass floor is made of reinforced glass with safety in mind.

2. Panoramic Views from the Observation Room

From the observation room at the far end, you can take in the Naruto Strait and watch the dynamic whirlpools up close.

On spring tide days, whirlpools tend to grow larger around high tide and low tide, and the spectacle is truly impressive.

The observation room also has free binoculars and benches, so you can relax and enjoy the scenery.

3. Learn How Whirlpools Form

The Naruto Whirlpools are caused by the tidal difference between the Seto Inland Sea and the Pacific Ocean.

Inside the walkway, display panels explain how the whirlpools form and introduce the natural environment of the Naruto Strait.

4. Whirlpools Change with the Season and Time of Day

Whirlpools are most likely to form for about 1 to 2 hours before and after high tide and low tide, and their size varies depending on the strength of the tides.

The official Uzu no Michi website and the websites of sightseeing boat operators publish daily “best viewing times,” so check before you visit.

5. Pair It with a Sightseeing Boat Cruise

If you want to feel the whirlpools even closer, combining your visit with a sightseeing boat cruise is recommended.

Several companies operate cruises, and from the boat you can experience the powerful whirlpools from just above the water’s surface.

By experiencing both the overhead view from the walkway and the water-level view from a boat, you can appreciate the whirlpools even more deeply.
