Japan is an island nation in the Pacific Ocean formed by tectonic plate movement. It is prone to natural hazards like earthquakes, tsunamis, typhoons, and volcanic eruptions due to its geography. Some of Japan's most destructive disasters include the 2011 Great East Japan Earthquake and tsunami, and the 1995 Great Hanshin-Awaji Earthquake. Japan has established a legal framework and plans at the national, prefectural, and municipal levels for disaster management.
