In Shinto religion, a yorishiro is an object capable of attracting kami, spirits such as elements of the landscape, souls of dead people, and forces of nature. A yorishiro is usually decorated with a shimenawa, a rope decorated with paper, used as a symbol of purification and that is believed to act as a ward against evil spirits. As Shintoism is deeply related to nature, yorishiro are usually natural objects like trees or rocks.
