Akadama is one of the three most famous Japan stones. It is a mineral formed when large amounts of iron oxide are combined with quartz under high temperature and pressure. Since ancient times, it has been said that the red color of Akadama can wards off evil spirits, and it has been considered an auspicious stone. It was originally mined around Sugiike Pond, where the dragon god is enshrined, but since 1980, Akadama has been protected and the amount in circulation has drastically decreased, making it rare now. It is a famous stone that it has a history of being presented to Toyotomi Hideyoshi.
