Natural disasters in JapanIn recent years, heavy rain accounted for the highest costs of damaged facilities. Heavy rain and floods are often caused by typhoons, which regularly hit Japan. The tropical cyclones develop over the Pacific Ocean and are likely to approach the archipelago between July and October, during the peak of the typhoon season. Japan's southernmost prefecture Okinawa gets hit regularly by typhoons, while the northernmost prefecture Hokkaido is the least affected area. Since the number of typhoons increased in recent years, the amount of damage caused by floods grew as well.
There are over 100 active volcanoes situated on the archipelago, which account for around ten percent of active volcanoes worldwide. Mount Fuji, which last erupted in 1707, is the tallest and most famous volcano in Japan. The volcano Sakurajima erupts several hundred times a year, representing one of the most active volcanoes in the country. In addition to intense volcanic activity, major earthquakes occur regularly, making the country vulnerable to tsunamis due to its oceanic setting.
