Japan experiences an average of three tsunamis per year due to its location on the Pacific Ring of Fire, which is prone to earthquakes and volcanic activity. The country has a long history of devastating tsunamis, including the Great East Japan Earthquake and Tsunami in 2011 that killed over 15,000 people. Japan has developed one of the most advanced tsunami warning systems in the world using seismographs and water level sensors to detect earthquakes and tsunamis. The government has also implemented measures such as building seawalls, zoning regulations, and evacuation plans to prevent or mitigate damage caused by tsunamis.
