From the lava plateau that looks like a roof, you can look out over the Seto Inland Sea, as it blends together with the islands and cityscape of Takamatsu. The drive to the summit is very popular, as you look out over the location where the famous Kagawa product aji stone is produced. At the summit, the 84th of the Shikoku 88 Holy Places (88 temples where pilgrims visit to rid themselves of bad luck and make wishes) is located at the Yashima Temple.  Although it is now connected, Yashima was a separate island in ancient times. It is said that a castle was built on top of the bluff, a natural protection against invaders from other lands.
