In August, in a long-standing tradition, the people who live in Ise are allowed to enter the area around the Inner Sanctum of the Naiku as well as the Geku. Some villages drag a wooden carriage laden with white stones up the Isuzu River onto the grounds of the Naiku. Each participant gets two white stones in a white handkerchief and these allow them to place the stones in the area around the Inner Sanctum. Other villages drag a huge wooden car or Noburi Kuruma laden with white stones to the Uji bridge at the entrance of the grounds of the Naiku. Participants receive two white stones which are also placed in the sacred space around the Inner Sanctum. The entire tradition is called Shiraisshiki and it is very colourful with every participant wearing a 'happi' coat representing a particular village. The rebuilding of the main shrine takes place on a site adjacent to the old, and each rebuilding alternates between the two sites. The next scheduled rebuilding of Naikū is due in 2033 on the lower, northern site. Various other religious ceremonies are held with the completion of the shrine, each serving different purposes.
