Daisho-in (大聖院, Daishōin) is one of the most important temples of Shingon Buddhism. It is located at the base of Mount Misen, on which the sect's founder, Kobo Daishi, first began the practice of Buddhism on the island of Miyajima.
Daisho-in features a variety of buildings, statues and other religious objects for visitors to admire. These include the Kannon-do Hall, the Maniden Hall, a sand mandala made by visiting monks from Tibet, a tea room and a cave filled with 88 icons representing the temples of the Shikoku Pilgrimage.
An interesting Buddhist ritual can be performed when walking up the temple's steps. Along the stairs is a row of spinning metal wheels that are inscribed with sutra (Buddhist scriptures). Turning the inscriptions as one walks up is believed to have the same effect as reading them. So, without any knowledge of Japanese, you can benefit from the blessings that the reading of sutra is believed to entail.
