Miyajima has been considered a holy place for most of Japanese history. In 806 AD, the monk Kōbō Daishi ascended Mt. Misen and established the mountain as an ascetic site for the Shingon sect of Buddhism. In the years since, the island’s Buddhist temples and Shinto shrines have maintained a close relationship.
In the past, women were not allowed on the island and old people were shipped elsewhere to die, so that the ritual purity of the site would not be spoiled; in fact, the island’s real name is Itsukushima 厳島, and Miyajima is just a popular nickname meaning “Shrine Island”.
Mt. Misen 弥山, 530 meters. If you have energy to spare, Mt. Misen offers gorgeous views of the island and sea. The hike takes about an hour, depending on rest stops along the way. Look for the signs for the ropeway, and when you reach it, just keep going.
