The world's tallest communications tower has been completed in central Tokyo following nearly four years of construction, reported The Telegraph. Tokyo Sky Tree, which measures 634 meters in height, was finished two months behind schedule following delays caused by last year's earthquake, tsunami and nuclear crisis. However, operators of Tokyo Sky Tree, which will operate as a communications tower for the nation's broadcasting networks, hope the timely completion of the tower just before the first anniversary of the disaster will help boost the nation's tourism industry, which was been hit hard over the past year.

The tower, located in Sumida block in the Asakusa district, is not only the loftiest communications tower ever built, it is also the world's second tallest building, eclipsed only by the 828 meters Burj Khalifa in Dubai.

More than 580 thousand workers were involved in the construction of the US$ 800 million structure, which was inspired by traditional Japanese architect and painted a shade of blue-tinged white called "aojiro".

Tokyo Sky Tree is set to become an iconic addition to the city's urban skyline, overshadowing other landmarks such as the 1958 red and white Tokyo Tower, which was previously used as the main broadcasting tower and long regarded a symbol of country's rapid post-war development.

Now the tower has been completed, and the operator plans to finish the interior for stores and other facilities with an eye to opening them to the public on May 22.
