Tokyo Skytree, at 634 meters the world's tallest broadcasting tower, is set to open to the public Tuesday.

Tobu Railway Co., the parent company of the operator Tobu Tower Skytree Co., expects about 200,000 visitors to flock to Tokyo Skytree Town on the first day alone to check out the newly completed 37,000-sq.-meter commercial complex in Sumida Ward.

The main attractions of the needlelike tower, topped by a communications mast, are two observation decks at 350 meters and 450 meters above ground level.
