This was my second visit to the Naruto Great Whirlpools. When I visited the first time, as I didn't have any knowledge about the whirlpools here, I couldn't witness the dynamic whirlpool. But this time...I DID!!
These whirlpools are created by the tide moving and removing the large amount of water in and out to and from the Pacific Ocean and the Seto Inland Sea. This time I learned what the best time to see the biggest whirlpool here is. That's when the speed of the current is at its fastest at spring tide. Naturally, if you'd like to know the exact best time, you'll need to check a tidal level chart, which can be referred to easily at this Web site!
