This is an "Ishiganto" stone ornament, combined with a Shisa, used as a charm against evil in Okinawa. It's a stone monument that has been used in Okinawan homes since ancient times to ward off evil spirits. It is believed that evil spirits can only move in a straight line, and by placing these at the end of T-junctions or three-way intersections, they are thought to prevent the entry of evil spirits. The combination of the Shisa and Ishiganto is believed to provide double the power of protection against evil. Thank you for viewing.
