A Well-known Genpei Battlesite: Yashima

The peak of Yashima is flat and resembles a roof, which is the origin of the name "Yashima," which means "roof island." There are three viewpoints located along a walking path atop the mountain, named Dankorei, Shishi no Reigan, and Yu-kakutei. From there, the entire Seto Inland Sea National Park can be seen, as well as the island-dotted Seto Inland Sea, and the cityscape of Takamatsu City. A battlesite from the Genpei War can also be seen on the mountain. In addition, the 84th temple in the Shikoku 88 Temple Pilgrimage, Yashima-ji, is located atop the mountain, as well as the Shin-Yashima Aquarium, which is said to be located highest above sea level of all the aquariums in Japan.
