Kibitsu Shrine was once the seat of the tutelary deity of all the Kibi Provinces, spanning from Okayama to modern Hiroshima prefecture. It was highly revered by the Japanese people, as well as the Imperial Court. It is also famous as the location of one of the battles between Prince Kibitsuhiko-no-Mikoto and the demon, Ura, which the famous Momotaro story is believed to have originated from.
While the original shrine was built in ancient times, the main sanctuary you see today was built in 1425, and the Zuijin Gate also dates to this time period (Muromachi). The 360 meter corridor was rebuilt in 1578, so the entire shrine is quite old and retains much historical and spiritual value. It is also a designated National Treasure. The shrine is quite unique in shape and very impressive to behold!
It is free to visit. A walk around the entire area takes about 45 minutes. The mountain behind the shrine (Kibi no Nakayama) is also an important historical site, as it has been written about in many ancient poems.
