Itsukushima Shrine (Japanese: Itsukushima-jinja) is a Shinto shrine on the island of Itsukushima (popularly known as Miyajima) in the city of Hatsukaichi in Hiroshima Prefecture in Japan. The shrine complex is listed as a UNESCO World Heritage Site and the Japanese government has designated several buildings and possessions as National Treasures.
The shrine is dedicated to the three daughters of Susano-o no Mikoto, Shinto deity of seas and storms and brother of the great sun deity, Amaterasu (tutelary deity of the Imperial Household). Because the island itself has been considered sacred, in order to maintain its purity commoners were not allowed to set foot on Miyajima through much of its history. In order to allow pilgrims to approach, the shrine was built like a pier over the water, so that it appeared to float, separate from the land, and therefore existed in a liminal state between the sacred and the profane. The shrine's signature red entrance gate, or torii, was built over the water for much the same reason. Commoners had to steer their boats through the torii before approaching the shrine.
The dramatic gate, or torii, of Itsukushima Shrine is one of Japan's most popular tourist attractions, and the most recognizable and celebrated feature of the Itsukushima shrine, and the view of the gate in front of the island's Mount Misen is classified as one of the Three Views of Japan (along with the sand bar Amanohashidate, and Matsushima Bay). Although a gate has been in place since 1168, the current gate dates back to 1875. The gate, built of decay-resistant camphor wood, is about 16 meters high and was built in a four-legged style to provide additional stability.
