It became the tallest construction in Japan in 2010 and reached its full height of 634.0 meters (2,080 ft) in March 2011, making it the tallest tower in the world, displacing the Canton Tower, and the second tallest structure on earth following the Burj Khalifa (829.8 m/2,722 ft).The tower is your primary television and radio broadcast website for the Kant? region; the elderly Tokyo Tower no longer provides complete digital terrestrial television broadcasting protection because it is surrounded by high-rise buildings.

Skytree was completed on Leap Day, 29 February 2012, with the tower opening to the public on 22 May 2012. The tower is the centrepiece of a large business development financed by Tobu Railway (which owns the complex) and a group of six terrestrial broadcasters led by NHK.

The Leaning Tower of Pisa (Italian: Torre pendente di Pisa) or simply the Tower of Pisa (Torre di Pisa [?torre di ?pi?za]) is the campanile, or freestanding bell tower, of the cathedral of this Italian city of Pisa, known globally for its almost four-degree lean, the result of an unstable foundation. The tower is situated behind the Pisa Cathedral and is the third-oldest structure in the city's Cathedral Square (Piazza del Duomo), following the palace and the Pisa Baptistry. The height of this tower is 55.86 metres (183.27 feet) from the ground on the low side and 56.67 metres (185.93 feet) on the high side. The width of the walls at the base is 2.44 m (8 feet 0.06 in). Its weight is estimated at 14,500 metric tons (16,000 short tons). The tower has 296 or 294 steps; the seventh floor has two fewer steps on the north-facing staircase. The tower began to lean during construction in the 12th century, due to soft ground which could not properly support the structure's weight, and it worsened through the completion of building in the 14th century. By 1990, the tilt had reached 5.5 degrees. The structure was stabilized by remedial work between 1993 and 2001, which decreased the tilt to 3.97 degrees.
