The panoramas from the second floor are impressive, even offering glimpses of Mount Fuji! Most visitors head to the two-story Main Observatory, which is at a height of 410 ft (125 meters) above ground. Understandably, the observation decks are the main attraction of the Tokyo Tower. Here’s why people love to visit the Tokyo Tower. Must-see features of the Tokyo Tower Tokyo Tower at night The Tokyo Tower was able to withstand the 2011 Tōhoku earthquake, though its 90-meter antenna did become slightly bent. The dampers reduce the stresses and shear force responses in the tower by more than 30%.

To control the heightened risk, Japanese engineers developed and installed a series of vibration control dampers, capable of controlling an adverse seismic response. The increase in dead weight had significant implications for the safety of the tower during an earthquake, as it would have the effect of amplifying any seismic shift that occurred. The Tokyo Tower was reinforced when it underwent digitization back in 2003.Īt the time the new antenna and transmitting equipment increased the weight of the tower by more than 10%. This included the installation of a ground-wave digital antenna and a new transmitter room, which was fitted above the tower’s special observatory. In 2003 the Tokyo Tower was retrofitted with ground-wave digital broadcasting equipment.
Specifications of the Tokyo Tower Owner The Tokyo Tower Company (Toei) Architect Tachū Naitō Construction Company Takenaka Corporation Location 4-chōme-2-8 Shibakōen, Minato City, Tokyo 105-0011, Japan Date completed December 1958 Cost $8.4 million Total height 1,093 feet (333 meters) Weight 4,000 tons Height of the top floor (observatory) 819 feet (249.6 meters) Number of floors 16 Number of lifts and elevators 4 Digitization of the Tokyo Tower Until the Tokyo Skytree was built in 2010, it was Japan’s tallest artificial structure. When its 90-meter antenna was installed in December 1958, the Tokyo Tower became the world’s tallest freestanding tower, exceeding the Eiffel Tower by just nine meters! After just over a year and at a cost of over $8.4 million, the tower was completed. The Tokyo Tower was built using steel that included scrap metal from US tanks that has been used in the Korean War. Repainting requires more than 28,000 liters of paint and is completed every five years. The tower was painted in bold red and white paint to comply with aviation law. The construction company used hundreds of traditional construction workers called tobi who flocked to the site for work.Ĭrews of approximately 400 construction laborers worked daily on the tower. The main contractor for building the tower was Takenaka Corporation. Construction of the Tokyo Tower Visiting Tokyo TowerĬonstruction commenced in June 1957. Naitō used his engineering expertise to ensure the tower could withstand earthquake and typhoon forces that exceeded the Great Kantō earthquake that had devastated Tokyo in the 1920s. He took inspiration for its design from the iconic Eiffel Tower in Paris, France.Īnother priority for the tower design was its ability to withstand earthquakes.
The Tokyo Tower was designed by the famous Japanese architect and engineer Tachū Naitō. However, the financial resources simply were not there to build such a large tower, so the height was limited to 1,093 feet (333 meters) which could achieve a transmission distance of 150 kilometers (93 miles) across the Kantō region. He had great aspirations for the tower, intending it to exceed the Empire State Building in height. The owner and operator of the Tokyo Tower was Hisakichi Maeda. The tower was not only a piece of technical infrastructure but it was also built as a symbol of the renewed ascendancy of Japan. The Tokyo Tower would become a telecommunications hub capable of supporting the technology and financial boom in postwar Japan.
