There are numerous locations throughout Japan that may very well experience a large M-8-class earthquake in the near future. For instance, if earthquakes were to strike simultaneously in the Tokai, Tonankai, and Nankai regions, it is estimated there would be 27,000 casualties and economic losses of some 94 trillion yen. Japan, a highly precipitous nation, is prone to flooding and landslide disasters during heavy rain. Such disasters claim many lives each year. Needless to say, firefighting and disaster prevention efforts are crucial to protecting lives and property from such natural disasters. We are conducting R&D on effective firefighting and disaster prevention efforts to be carried out in case of large-scale natural disasters, such as earthquakes.
