Four-way observation deck and heart-shaped island "Kagamishima"

<Yomomitenboudai> Located on the Naruto Skyline, a driving course that takes in the breathtaking views of the sea and mountains, you can enjoy the magnificent view of Uchinoumi, where fishing huts float. A panoramic signboard has been installed that lists the scenery that can be seen from the observation deck and the names of the places. <Kagamishima> It has recently been discovered that the uninhabited island of Kagamishima, located in Uchinoumi, Naruto City, is heart-shaped when viewed from the sky. The viewing point is the Naruto Skyline Yomomitenboudai. However, while Kagamishima is clearly visible, unfortunately the heart shape cannot be seen from the observation deck. There are various theories about the heart-shaped island, but in ancient times, when the country was small, Emperor Jimmu, who looked out over the country from the top of a mountain, wrote that the country was "like dragonflies mating."
