Japan is one of those countries most often affected by powerful natural hazards: earthquakes, tsunamis, volcanic eruptions, typhoons, heavy rains, heavy snowfall, tornadoes, etc. The Archipelago is considered a very advanced country in terms of forecasting, prevention and management of natural disasters. A detailed analysis of the reality of recent years is however necessary. In the run-up to the 2020 Olympic Games in Tokyo, among others, a publication on the subject will inform a large number of people wanting to know more about the risks of natural disasters in Japan.
