What are the Naruto Whirlpools?
The Naruto Whirlpools (Naruto no Uzushio) are one of the world’s largest tidal current phenomena, visible in the Naruto Strait that connects Naruto City in Tokushima Prefecture with Awaji Island in Hyogo Prefecture.
The whirlpools that form at high and low tide can exceed 20 meters in diameter, and their magnificent scale attracts visitors from both Japan and abroad.
You can enjoy these whirlpools up close on the Ōnaruto Bridge Walkway, "Uzu no Michi".
The view of the whirlpools from the bridge is dramatic and makes for an unforgettable experience.
Attractions of the Ōnaruto Bridge Walkway
1. A sky-walk experience
The Ōnaruto Bridge Walkway is an approximately 450-meter-long promenade installed directly above the Naruto Strait.
Parts of the floor are made of glass, allowing you to walk while looking straight down at the whirlpools.
Those with a fear of heights may find it a little thrilling, but that makes it a uniquely special experience.
2. Spectacular views from the observation deck
From the observation deck at the end of the walkway you can take in the full view of the Naruto Strait and watch the dynamic movement of the whirlpools.
On especially large tides the whirlpools grow even more powerful and impressive.
3. Learn the mechanism of tides and whirlpools
The Naruto whirlpools are caused by the difference in tidal levels between the Seto Inland Sea and the Pacific Ocean.
There is an exhibition area within the walkway where you can learn about how the whirlpools form and about the natural phenomena of the strait.
This lets you deepen your understanding of the whirlpools, not just view them.
4. Different appearances by season and time of day
Whirlpools are most likely to form around high and low tide, and their size and beauty change with the season and time of day.
Whirlpools sparkling in the morning sun or the strait dyed by the evening sun each offer a different emotional experience.
5. Combined tours with the Naruto whirlpool boats
If you want an even closer look at the whirlpools, consider a combined tour with a whirlpool sightseeing boat.
You can experience both the panoramic view from the walkway and the thrilling perspective from onboard a boat.
