About Mirrors in Shinto
A Shinto mirror Shinkyou (神鏡) is a mirror sacred in Shinto. Some mirrors are enshrined in the main hall of a shrine as a sacred object of the divine spirit, or are placed in front of the deity in a hall of worship. Mirrors in ancient Japan represented truth because they merely reflected what was shown, and were a source of much mystique and reverence. Japanese folklore is rich in stories of life before mirrors were commonplace.
