Naruto Whirlpools Japan ポストカード

The Naruto Whirlpools are a breathtaking natural phenomenon occurring in the narrow strait between Shikoku and Awaji Island. Created by the meeting of tides from the Seto Inland Sea and the Pacific Ocean, these massive vortices can reach diameters of up to 20 meters. Observers can view the swirling patterns from sightseeing boats or the glass-floored Uzu no Michi walkway built into the Onaruto Bridge. The dynamic movement of the water creates a powerful spectacle of nature’s raw energy and beauty.
