The whirlpools in the Naruto Strait can reach speeds of up to 20 kilometers per hour, making them among the fastest in the world.
The Naruto Whirlpools occur four times a day, roughly every six hours, dictated by the lunar cycle.
The Onaruto Bridge was completed in 1985 and was designed to accommodate a future Shinkansen rail line that was never constructed.
The depth of the Naruto Strait reaches up to 90 meters at its deepest point, contributing to the intensity of the water currents.
The park offers views of the 'shio-meguri' or whirlpool-viewing boats that navigate the narrow channel.
Naruto Park is situated at the northern end of Naruto City, overlooking the Naruto Strait where the Kii Channel meets the Harima Sea. The park is most famous for its proximity to the Naruto Whirlpools, which are caused by extreme tidal current differences between the two bodies of water. The Uzunomichi walkway, located beneath the Onaruto Bridge, allows visitors to view these whirlpools from 45 meters above the water through glass floor panels. The park grounds feature several observation decks and walking trails along the cliffside. On-site dining options include restaurants serving local specialties such as Naruto sea bream and wakame seaweed. The area provides direct views of the Onaruto Bridge, a 1,629-meter long suspension bridge connecting Shikoku to Awaji Island. Extensive parking and visitor facilities are integrated into the park infrastructure. The park serves as the primary gateway for viewing the tidal phenomena in the Naruto Strait.

Check the official tide table online before traveling, as the whirlpools are only visible during specific shift periods.
Bring a windbreaker or light jacket, as the park’s cliffside location is frequently exposed to strong coastal winds.
Utilize the binoculars available at the various observation decks for clearer views of the bridge supports.
Do not rely on arriving at a random time to see the whirlpools; without checking the tide schedule, you are likely to see only calm water.
The Uzunomichi walkway undergoes periodic maintenance closures, typically once every few months for one day; check the official website before departure.
