When entering the grounds of a Shinto shrine in Japan, it’s customary to first stop by the water basin near the gate and rinse your hands, and sometimes your mouth, in order to cleanse them. Water isn’t the only classical element held to have purifying properties in Shintoism, though, since the same can be said about fire.
Obviously, worshippers aren’t called upon to put fire on their palms or inside their mouths. Instead, Shinto priests light pyres of charms and decorations during the Dondo Yaki ceremony, with the towering blazes regularly reaching 15 meters (49.2 feet) into the air.
