[Whirlpools of the Naruto Strait in Japan] Very impressive! The world's largest whirlpool

I boarded the Uzushio cruise ship Kanrin Maru from Fukura Port on Awaji Island.
On this day, the best timing is when the spring tide and new moon coincide.
Furthermore, I tried to board the ship at a time when the probability of a large eddy occurring was high.
Check out this impressively beautiful natural phenomenon.
