The Naruto Strait is a narrow body of water located between the islands of Shikoku and Awaji in Japan. It connects the Seto Inland Sea to the Pacific Ocean and is known for its strong tidal currents, which can reach speeds of up to 20 knots. The strait is approximately 1.5 kilometers wide at its narrowest point. This strait is famous for the Naruto Whirlpools, which are large whirlpools that form due to the tidal changes. These whirlpools attract tourists and are a popular sight, especially during certain times of the year. The area is also rich in marine life, making it significant for local fishing industries.
