Onaruto Bridge

Utsunomichi Road is a sea promenade built within the bridge (under the lane) of the Onaruto Bridge over the Naruto Strait. Watching whirlpools on a glass floor as high as 45 meters is exciting. You can take a walk on the sea while enjoying the spectacular scenery on the bridge. There are 4 glass floors on the way of the passage, and it is creepy to see the whirlpool through the glass windows. In the design, in order to reduce the influence of wind on the bridge itself, iron mesh is used on both sides of the passage. The observation room structure at the front end of the promenade is a circular structure that makes full use of the beam space. This place is located 45 meters above the sea above the land. From here, you can see the Naruto Maelstrom and the roaring rapids with your own eyes through the glass floor. Usually, you can see the view of the Pacific Ocean, but also the ever-changing scenery of the Seto Inland Sea.
