Design is a beautiful thing. Functional design is beauty with purpose. Due to its location right on the Ring of Fire, at the intersection of several very active tectonic plates Japanese architects, engineers and construction professionals are very well versed in creating beautifully functional design.
Just take a look at the Skyscrapers of one of the cities, sorry i can’t read Japanese so I don’t know which, swaying during the massive 8.9 quake. Rigid objects break much easier than those that literally go with the flow. Imagine the horror if the design hadn’t been beautiful and functional?
