Japan is the most earthquake prone country on the planet. Across the country there are earthquakes every day. Due to this, the building structures in Japan have to be built to be earthquake resistant. This prevents tall buildings from breaking during an earthquake. Small earthquakes go unnoticed and are not talking about. Japanese people are so used to earthquakes that there is no panic when a small one occurs, people continue doing what they were doing, and some people don't even notice the earthquake. Larger earthquakes can cause tsunamis, building damage and people can die from falling objects.
A typhoon is a tropical storm that occurs in the North western part of the Pacific Ocean. Hurricanes, Typhoons and Cyclones are all the same thing; they just have a different name depending on where they occur. Japan is prone to Typhoons, especially Okinawa region which usually gets hit first by a typhoon that occurs.
