Let°«s view the dynamic whirlpools from 45M above the sea!

Observation gallery
The observation gallery provides a full 360-degree view, which is located at the end of the promenade, 450 meters from the abutment. Once you look directly down on the sea through the glass floor, you can feel the roaring whirlpools and strong tides. You must be impressed by the magnificent view of the Pacific Ocean and the Seto Inland Sea.

The mechanism of whirlpools

What causes tides?
Tidal currents cause the whirlpools at the Naruto Straits. The tide flows in and out due to the gravitational effect of the moon and the sun on the Ocean. As the earth rotates around its axis each day, the high tide alternates with the ebb tide twice a day, making each cycle about 6 hours long.
