Stairway of Naiku
The Ise Grand Shrine located in the city of Ise, Mie Prefecture of Japan, is a Shinto shrine dedicated to the sun goddess Amaterasu. Officially known simply as Jingū, Ise Jingū is a shrine complex composed of over 125 shrines centered on two main shrines, Naiku and Geku.
Every 20 years, Amaterasu-Omikami and the other deities are relocated to newly constructed buildings at the same site by Jingu priests in a special ritual called Shikinen Sengu.
Every year especially on New Year Day, it is customary for people from all over Japan to make a pilgrimage to Jingu to offer their sincere prayers for a good year ahead.

History
Amaterasu-Omikami was originally worshipped in the Imperial Palace by successive Emperors of Japan. However, during the reign of the 10th Emperor Sujin, the Holy Mirror (the symbol of Amaterasu-Omikami) was moved from the Imperial Palace. Then, during the reign of the 11th Emperor Suinin, the Emperor ordered his princess, Yamatohime-no-mikoto, to seek the most appropriate place to permanently enshrine and worship Amaterasu-Omikami. After searching in many regions, finally the princess received a revelation that Amaterasu-Omikami should be enshrined and worshipped eternally in Ise. It is approximately 2,000 years ago.
In the era of the 21st Emperor Yuryaku, about 1,500 years ago, Toyo’uke-no-Omikami was, in accordance with another revelation from Amaterasu-Omikami, summoned from the north of Kyoto prefecture and enshrined in Ise.
