Naruto Strait travel FAQs and useful info

What causes the Naruto Whirlpools?

The Naruto Whirlpools are caused by the massive tidal exchange between the Kii Channel and the Harima Sea. When the tide is high in the Kii Channel, water flows towards the Harima Sea, and vice versa. This powerful ebb and flow, occurring every six hours, creates the impressive whirlpools on either side of the strait.

Does 'Naruto' mean Whirlpool?

While the famous anime character 'Naruto' is named after the food topping naruto, which itself is named after the 'naruto whirlpools' that form under bridges, the term 'Naruto' in this context is intrinsically linked to the spiral or vortex motion seen in these natural phenomena. The Japanese word 'Uzumaki' also translates to spiral or whirlpool.

Is visiting the Naruto Strait worth it?

Absolutely. The Naruto Strait offers a very impressive natural phenomenon in a beautiful setting. The Uzu-Michi observation deck, spanning across the strait, provides an excellent vantage point to witness the powerful whirlpools and the scenic surroundings. It's a unique and memorable experience.

Where is the Naruto Strait located?

The Naruto Strait is situated between Naruto City in Tokushima Prefecture and Awaji Island. This strait is renowned for its spectacular tidal whirlpools, and the promenade above the ocean across the strait serves as a popular tourist attraction.

What is the best way to see the Naruto Whirlpools?

The most popular way to experience the Naruto Whirlpools is by taking a dedicated boat tour that navigates close to the whirlpools, offering thrilling views. Alternatively, you can visit the Uzu-Michi observation deck, which is a glass-floored walkway extending over the strait, providing a unique perspective from above.
