This is the 63rd reconstruction cycle. The first was documented in 690, during the reign of Empress Jito, said Noboru Okada, professor emeritus at Kogakkan University and a specialist in Japanese history and archaeology. All 125 shrine buildings will be demolished, and identical structures, as well as more than 1,500 garments and other ritual objects used in the shrine, will be rebuilt using techniques that have been painstakingly passed down over generations. There are 33 accompanying festivals and ceremonies, culminating in a 2033 ritual that sees the presiding deity transferred to the new shrine.
