Tokyo Skytree is one of the largest towers in Japan and the second largest tower in the world after Burj Khalifa. It is a broadcast and observation tower located in Sumida, Tokyo. It became the tallest structure in Japan in the year 2010 with its full height being 634 meters.
Tokyo sky tree is currently the primary television and radio broadcast site as the old Tokyo tower due to its surrounding high rise buildings is not capable of providing TV broadcast service. Skytree was completed on 29th February 2012 and open to the public on 22nd May 2012. Tokyo Skytree is owned by Tobu Railway and nearby train stations to visit Tokyo Skytree include Tokyo Skytree Station and nearby Oshiage Station.
Tokyo Skytree also resembles a 5-storey pagoda from historical Japan. The base of the tower has a structure similar to a tripod; from a height of about 350 m and above, the tower’s structure is cylindrical to offer panoramic views of the river, Mount Fuji and the city. There are observatories at 350 m with a capacity of up to 2000 people, and 450 m with a capacity of 900 people. The upper observatory features a spiral, glass-covered skywalk in which visitors ascend the last 5 meters to the highest point at the upper platform. A section of glass flooring gives visitors a direct downward view of the streets below.
As you know Japan lies in the region of Ring of Fire and is a constant place to experience Earthquakes, Tokyo Skytree is built with seismic proofing where the central shaft is made from reinforced concrete. For the first 125m above the ground, the main pillar is attached to the outer tower and from 125m to 375m, the pillar is attached to frames with oil dampers. An added mass control mechanism is provided to the structure which during the earthquake it moves out of the building structure which in turn maintains gravity. It is said that the dampers can absorb about 50% of energy from an earthquake.
The colour of Tokyo Skytree is painted bluish-white which is based on traditional Japanese colour called aijiro. In the year 2009, the illumination was selected where two illumination patterns called Iki and Miyabi was illuminated alternate days.
Tokyo Skytree currently has 9 TV broadcasters and 5 Radio Broadcasters serving here. Out of the 9 TV broadcasters, 8 has a broadcast area to Kanto Region and 1 in Tokyo and out of 5 Radio Broadcasters 3 broadcasts to South Kanto region and 2 for Tokyo region.
