This is the tallest tower in the world!
Tokyo Skytree stands in Sumida-ku, Tokyo.
Construction of Tokyo Skytree was completed on February 29th, 2012, three and a half years after its beginning on July 14th, 2008.
It is hard to recognize from far but the base of the tower is triangular utilizing a very limited space. It gets round as it goes up.
The height of the tower is 634m (2080ft).
It is the tallest tower in the world.
It has two observation decks.
One is located at 350m(1148ft) high and the second one is 450m(1475ft)high with a 360 degree panoramic view. There are 4 elevators to the first observation deck that has the capacity of 40 passengers in each. It has the max speed of 600m/min which takes you up to the first observation deck in 50 seconds.
The best architectural techniques in Japan!
Tokyo Skytree is made by assembling 37 thousand iron frames.
Its gross weight is 36 thousand tons.
The biggest one among the iron frame columns which hold up Skytree is 2.3 m diameter, 10 cm thickness and 4 m length.
In order to supply such large amount of iron frames in a short period of about two years with concentrated power, Japanese major steel manufacturers and steel machine manufacturers worked together.
Steel poles manufactured across Japan were carried in the construction site after another.
Then, the iron poles hung with the special crane are lifted within some millimeters of error.
What we are astonished with is that the final welding is done by hand.
The architecture technique and the skill of the craftsmen in Japan support the world’s best tower.
The biggest part of Skytree is the huge panorama where we can overview the Kanto region from the uppermost floor.
The “Skywalk corridor” especially provides us with an enjoyable view while walking slowly by ourselves.
The view should surely be nothing but superb.
During the Sumida river fireworks festival, you can apparently see the fireworks down below. On rainy days, it feels as if you were floating above the clouds, so there are many ways of enjoying the views from here.
This is the last part of the sky corridor. Right under you can see the starting point. The difference is about 5 meters. Try to taste the satisfaction of reaching the peak on your own!
The fusion of tradition and high-tech! What are the newest anti-earthquake measures!?
With a tower as high as this one, it’s difficult not to worry about the earthquakes.
You may be worried about such a tall tower tipping over in earthquakes: “What would happen if an earthquake strikes when I’m on its observation deck?”
But, no worries.
Tokyo Skytree was constructed with state-of-the-art vibration control technology developed in Japan, an earthquake-prone country, by combining traditional Japanese architectural technology and highly advanced technology.
The new technology is, in fact, inspired by the traditional architectural technology used in five-story pagodas.
Indeed, there are few cases reported in which traditional five-story pagodas in Japan collapsed in earthquakes over the last 1500 years since their oldest construction.
The secret is the structure called Shinbashira (central pillar of a pagoda).
Five stories of the inside of the pagota are connected only by Shin-bashira(central pillar) that supports the top part of the tower which is called Sorin.
In other words, the ceter has a open hollow structure and Shin-bashira is structurally independent from the tower body.
According to a theory, the reason why five story-pagota does not collapse is that Shinbashira has a roll of a pendulum and has an effect to control the moving.
So, they decided to build the inside of Skytree in well-hole style and set up Shin-bashira.
The central pillar of Skytree vibrates at a different cycle than the rest of the building, effectively negating the power of the earthquake.
This is the demonstration of how high technology can control the earthquake tremors – you are entirely safe even at the top of the building.
Skytree is also the reason for why the city around it became so much more lively.
Skytree became the spiritual center of the Sumida Ward of Tokyo where it is currently standing. Since a long time ago, Sumida Ward was considered to be the city of manufacturers. Now, thanks to Skytree, the small factories and traditional art centers has been revitalized, and the city still makes an effort to pump more life into the district.
The look of Skytree beyond the narrow alleys of the old-fashioned wooden building. Try to visit at least once Sumida, the traditional city that coexists with advanced technology.
