In Shinto, cult images are called shintai. The earliest historical examples of these were natural objects such as stones, waterfalls, trees or mountains, like Mount Fuji, while the vast majority are man-made objects such as swords, jewels or mirrors. Rather than being representative of or part of the kami, shintai are seen as repositories in which the essence of such spirits can temporarily reside to make themselves accessible for humans to worship. A ceremony called kanjō can be used to propagate the essence of a kami into another shintai, allowing the same deity to be enshrined in multiple shrines.
