45m above the whirlpool! Walk a spectacular view on the sea promenade in the bridge

"Uzunomichi" is a marine promenade built inside the bridge girder of Onaruto Bridge over the Naruto Strait (below the roadway). You can enjoy a walk on the sea while blowing 450m to the observation room in the sea while watching the magnificent Naruto Strait from left to right.

The tide of the Naruto Strait is said to be one of the "world's three major tides" along with the Messina Strait in Italy and the Seymour Strait in Canada. At the maximum tide, the speed of the tide is 20 km / h or more, and is said to be the fastest in Japan.

The observation room at the end of the promenade is a migratory type using the bridge girder space of Onaruto Bridge, and when you look into the Naruto Strait from the glass floor at your feet, you can experience the whirlpools and roaring tides. Please enjoy the excitement and thrill.

The whirlpool tide is caused by the difference in ebb and flow, so the best time to see varies depending on the day. We recommend that you check in advance on "Shiomi Omote" on the Uzunomichi official website.
