The Tokyo Skytree, twice as tall as the Eiffel Tower, and its surrounding retail and office complex opened on Tuesday with thousands lining up in the rain for a first look at the 143 billion yen ($1.8 billion) development.
Tokyo Skytree with it's 634m tower took four years to build and surpassed the 600-metre Canton Tower in Guangzhou, China, as the world’s tallest, according to the Council on Tall Buildings and Urban Habitat. Dubai’s Burj Khalifa is the tallest building at 828 meters.
A tower is a structure where less than half the height is occupied by usable floor space, according to the council. The tower, which cost 65 billion yen on its own, has two observation decks, one at 350 metres and another at 450 metres. A trip to the lower deck will cost 2,000 yen.
