Japan+has+fluctuating+buildings.

Japan is a very unique place. Not to mention their buildings. Sense Japan is notorious for earthquakes they have made special buildings that move with the earthquakes. This is just one of the big things Japan did to prepare for earthquakes. They have designed this technology called Mass Dampers. A Mass Damper is almost a dome looking thing that sits within this room at the very top of the building. The point of one of them is to help the building move with the earthquake. When a earthquake accurs the Mass Damper will send a message to a computer telling it to help move along so there is less destruction to the building.
