The infamous Sessho-seki, a protected boulder in the volcanic area of Mount Nesu in Japan, has split. The break occurred around March 5, 2022. A legend says the stone was the prison of the evil nine-tailed fox demoness Tamamo-no-Mae and that anyone who touched it died. Some people fear that evil has been released into the world. In reality, the stone had been cracked for a while and held by a rope. The rock likely split from natural weathering processes. The area is known for sulfur hot springs and potentially poisonous gases which may have contributed to the “killing stone” myth.
