Rising above the Tokyo skyline is a structure that looks like a conglomeration of the Eiffel Tower and the Seattle Space Needle. It is one of the tallest structures in the world, and it combines Tokyo’s futuristic character with traditional Japanese values. How?
The Tokyo Skytree was built using the same principles as the Japanese pagoda, a type of tower with many roofs stacked atop one another. Its stability springs from its central pole, called a shinbashira. In the case of the Skytree, this central pole is in the form of a massive concrete tube, fastened to the rest of the tower using fuel dampers invented by NASA. Even in an earthquake, the tower is designed to sway against this pole without sustaining harmful structural damage.
