The Yomomi Observation Deck is the tallest observation deck on the Naruto Skyline, and from it the dynamic surrounding nature can be both seen and felt. If you gaze out, you'll be able to see the Uchinoumi Inland Sea, the Naruto Strait, which is one of the three major currents of the world, and the Kii Channel. If the weather is good, you'll be able to see all the way to Shodoshima Island across the Seto Inland Sea. The Uchinoumi Inland Sea is surrounded by slightly elevated mountains, so at first glance it seems like a lake; because of these surrounding mountains, it isn't affected by high waves, creating ideal fishing grounds. This is an area full of nature, wild birds, and seasonal flowers, and it is an excellent destination for car or motorcycle travel.
