Shutdowns due to poor weather were to blame for missing the targeted number of visitors to the observation deck of Tokyo Skytree in fiscal 2013, the operator's officials said.

Almost 6.2 million people visited the observation deck of the world's tallest broadcasting tower in the year ended March, short of the 6.44 million expected by Tobu Tower Skytree Co.

While the number still exceeded the 5.54 million in fiscal 2012, the deck was closed on more days due to sudden weather changes, the officials said.

Including Tokyo Solamachi, the adjacent commercial facilities, there were 39.27 million visitors in the year through last March, about 730,000 short of the projection made at the start of the year.

In fiscal 2014, the operator expects 35 million visitors, including 5.97 million to the observation deck. The 634-meter tower and the adjacent facilities opened to the public in May 2012.
