Purportedly the home of the Sacred Mirror, the shrine is arguably one of Shinto’s holiest and most important sites. Access to both sites is strictly limited, with the common public allowed to see little more than the thatched roofs of the central structures, hidden behind four tall wooden fences. The High Priest or Priestess of Ise Shrine must come from the Japanese Imperial Family, and is responsible for watching over the Shrine.
The two main shrines of Ise are joined by a pilgrimage road that passes through the old entertainment district of Furuichi. The region around the shrines consists of the Ise-Shima National Park and numerous other holy and historic sites including the ‘wedded rocks’ Meoto Iwa, and the Saiku (the site of the Heian period imperial residence).
