Earthquakes and tsunamis have been hitting Japan for thousands of years and it never made anyone move away before guess they just deal with them.Besides most every place in the world could get more or less wiped out but some natural disaster or another some places by more than one type.They are also easily the most well prepared country for such events.I say live where you want and enjoy your life why bother worrying about things you have no control over something is going to kill you sooner or later if you avoid Japan because you fear earthquakes you will just wind up getting hit by a bus or bitten by a tunnel spider or get attacked by a swarm of passively killing killer bees.
Take the Midwest for example few people know that some the strongest earthquakes in the US have occurred there not in California and a quake could occur anytime at least California has some preparation the Midwest has basically none.
One of the strongest quakes ever was in Alaska but most people don't know about that either.That is what I love about mother nature she likes to show us humans who is boss from time to time.
