Final answer:
Japan's location on the Pacific Ring of Fire, known for frequent earthquakes and tsunamis, explains why there is a strong emphasis on regular disaster preparedness drills in schools.
Step-by-step explanation:
Japan's location as part of the Pacific Ring of Fire explains the emphasis on regular school disaster preparedness drills. This is because the Ring of Fire is a zone of frequent earthquake and volcanic activity, which has historically caused devastating tsunamis and necessitates stringent safety measures.
Tsunamis originating from earthquakes near Japan have the potential to cause destruction to coastal regions in their path, and the 2011 earthquake off the east coast of Japan triggered a tsunami that resulted in significant damage, including to nuclear energy facilities. Thus, the focus on disaster preparedness in schools is a critical response to the inherent geological risks posed by Japan's location within this active tectonic zone.
