Highlights

Naruto Whirlpools and Uzunomichi Quick Guide

The Naruto whirlpools are a major tidal-current phenomenon in the Naruto Strait, considered among the world’s largest. The Uzunomichi walkway under the Onaruto Bridge lets you observe them from a glass floor about 45 m above the sea.

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 Walkway Experience

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.

Viewing Deck and Educational Displays

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.

Access (From IC and Station)

By car, it’s a few minutes from Naruto-kita IC to the Naruto Park paid parking area. From JR Naruto Station, take a bus about 15 minutes to “Onaruto Bridge Memorial Museum-mae,” then walk about 5 minutes.

Opening Hours and Fees

Hours vary by season (with last entry times). Rough guide: Mar–Sep 9:00–18:00 (last entry 17:30), Golden Week and summer vacation 8:00–19:00 (last entry 18:30), Oct–Feb 9:00–17:00 (last entry 16:30). Regular closures include the 2nd Monday in March, June, September, and December, among other dates, so check the latest details before visiting. Admission is ¥510 for adults, ¥410 for middle/high school students, and ¥260 for elementary school students.

Best Timing and Combo Ideas

The best views are around high and low tide times. In addition to the overhead view from Uzunomichi, combining it with a whirlpool sightseeing boat offers a more three-dimensional sense of the scale.

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.

Frequently Asked Questions

A. The Naruto Whirlpools are famous as one of the largest natural tidal phenomena in the world, created by the difference in sea level between the Seto Inland Sea and the Kii Channel. During spring tides in spring and autumn, some whirlpools can reach around 20 to 30 meters in diameter. It is best enjoyed not simply as a sea-view spot, but as a place to watch the movement of the tides themselves.
A. Uzu no Michi costs 510 yen for adults, 410 yen for junior high and high school students, and 260 yen for elementary school students. Opening hours are 9:00 to 18:00 from March to September and 9:00 to 17:00 from October to February, with extended hours of 8:00 to 19:00 during Golden Week and the summer holiday period. Windy days are common, so traveling light is often more comfortable than worrying about a hat.
A. From JR Naruto Station, take a Tokushima Bus bound for Naruto Park for about 25 minutes, get off at “Naruto Koen,” and walk about 5 minutes. Since there are slopes and stairs in the park area, it is better to arrive a little early rather than right at the best viewing time, then start walking so you reach the whirlpools at their peak.
A. The whirlpools are most dramatic for about 1.5 hours before and after the fastest tidal current, and they become especially large during spring tides in spring and autumn. The best time changes every day, so checking the tide table first and then planning your transport and meals makes it easier to avoid arriving when the whirlpools are weak.
A. If you want to see the overall flow of the whirlpools from above, Uzu no Michi is the better choice. If you want a closer, more powerful view near the sea surface, a sightseeing boat is better. There are two main boat options: the large Wonder Naruto, which does not require a reservation, and the smaller Aqua Eddy, which is reservation-only, so choosing based on how comfortable you are with motion tends to work well.
A. No reservation is needed for Uzu no Michi. For the Uzushio sightseeing boats, the large Wonder Naruto does not require a reservation, but the smaller underwater sightseeing boat Aqua Eddy is reservation-only. Since departures around the best viewing times get busy, it is easier to move around if you arrive a little early on days when you are not booking ahead.
A. If you want to capture the whirlpools themselves, timing your visit for the best viewing period is the top priority. Rather than shooting directly above the glass floor, including the flow of the sea from a slight angle often creates a stronger image. Since wind can easily blow away smartphones or hats, a wrist strap and pockets with zippers are very useful.
A. Eddy, the Ohnaruto Bridge Crossing Memorial Hall, is very close to Uzu no Michi and easy to combine, about a 3-minute walk away. If you have more time, extending your visit to Esca Hill Naruto or the Otsuka Museum of Art makes it easy to plan a half-day route that includes more than just natural scenery.
